123-518: Water is relatively abundant in New Zealand due to the temperate climate and maritime weather patterns. In recent years, water pollution and draw-down of aquifers have become important environmental issues in New Zealand . In New Zealand, there are more than 425,000 km (264,000 mi) of rivers and streams and about 4,000 lakes and over 200 underground aquifers. Annual water flow

246-557: A minority government can be formed if support from other parties during confidence and supply votes is assured. The governor-general appoints ministers under advice from the prime minister, who is by convention the parliamentary leader of the governing party or coalition. Cabinet , formed by ministers and led by the prime minister, is the highest policy-making body in government and responsible for deciding significant government actions. Members of Cabinet make major decisions collectively and are therefore collectively responsible for

369-471: A protectionist and highly regulated economy to a liberalised free-trade economy. Unemployment peaked just above 10% in 1991 and 1992, following the 1987 share market crash , but eventually fell to 3.7% in 2007 (ranking third from twenty-seven comparable OECD nations). However, the global financial crisis that followed had a major effect on New Zealand, with the GDP shrinking for five consecutive quarters,

492-589: A copy was sent to King William IV who had already acknowledged the flag of the United Tribes of New Zealand, and who recognised the declaration in a letter from Lord Glenelg . Aotearoa (pronounced [aɔˈtɛaɾɔa] in Māori and / ˌ aʊ t ɛəˈr oʊ . ə / in English; often translated as 'land of the long white cloud') is the current Māori name for New Zealand. It is unknown whether Māori had

615-446: A high level of innovation . Poverty in New Zealand is characterised by growing income inequality; wealth in New Zealand is highly concentrated , with the top 1% of the population owning 16% of the country's wealth, and the richest 5% owning 38%, leaving a stark contrast where half the population, including state beneficiaries and pensioners, receive less than $ 24,000. Moreover, child poverty in New Zealand has been identified by

738-529: A high rainfall so any potential pollution will be diluted to some degree. Until recently untreated sewage was being discharged into the Grey River but government funding was made available to build a sewage treatment plant. New Zealand New Zealand is an island country in the southwestern Pacific Ocean . It consists of two main landmasses—the North Island ( Te Ika-a-Māui ) and

861-563: A name for the whole country before the arrival of Europeans; Aotearoa originally referred to just the North Island . Māori had several traditional names for the two main islands, including Te Ika-a-Māui ( ' the fish of Māui ' ) for the North Island and Te Waipounamu ( ' the waters of greenstone ' ) or Te Waka o Aoraki ( ' the canoe of Aoraki ' ) for the South Island . Early European maps labelled

984-489: A number of purposes, including hydroelectricity generation, irrigation, and municipal water supply. Approximately 2% of New Zealand's freshwater resource is allocated for consumptive use. The supply of water to consumers is provided by local government territorial authorities , which include city councils in urban areas and district councils in rural areas. The legal framework includes the Health Act 1956, amended in 2007,

1107-455: A number of recent pollution incidents. Environment Canterbury recently introduced strict new environmental requirements for the region's farmers, requiring most farms to develop Farm Environment Plans showing how farms will take action to mitigate risks like nutrient leaching, soil erosion, effluent risks and protect waterways through actions such as fencing off waterways and undertaking riparian planting. The plans are independently audited. Since

1230-785: A party must win at least one electorate or 5% of the total party vote before it is eligible for a seat. Elections since the 1930s have been dominated by two political parties , National and Labour . More parties have been represented in Parliament since the introduction of MMP. New Zealand's judiciary , headed by the chief justice , includes the Supreme Court , Court of Appeal , the High Court , and subordinate courts. Judges and judicial officers are appointed non-politically and under strict rules regarding tenure to help maintain judicial independence . This theoretically allows

1353-503: A shared Trans-Tasman identity between the two countries stemming from centuries of British colonisation. Nationally, legislative authority is vested in an elected, unicameral Parliament , while executive political power is exercised by the Government , led by the prime minister , currently Christopher Luxon . Charles III is the country's king and is represented by the governor-general , Cindy Kiro . In addition, New Zealand

1476-558: A significant Act of Parliament that regulates natural and physical resources such as land, air and water. Differing land use and climate means that water pollution varies across the regions. In 2020, the National Policy Statement for Freshwater Management set safe "bottom line" levels for nitrogen, phosphorus, sediment and E. coli in New Zealand's rivers, lakes, and estuaries. A study by Our Land and Water National Science Challenge measured these levels throughout

1599-639: A trade which provided the basis for strong economic growth in New Zealand. High demand for agricultural products from the United Kingdom and the United States helped New Zealanders achieve higher living standards than both Australia and Western Europe in the 1950s and 1960s. In 1973, New Zealand's export market was reduced when the United Kingdom joined the European Economic Community and other compounding factors, such as

1722-904: A waterway on a deer farm reduced contaminants, including the indicator bacterium E. coli , by 55–84%, but nitrate concentrations doubled, and suspended sediment was increased from animals creating tracks along the fences. Over the past decade, regional councils have increasing imposed more regulatory requirements on farmers to reduce their environmental impacts. A number of councils - including Environment Canterbury, Horizons Regional Council and Hawke's Bay Regional Council require most farms to have Farm Environment Plans in place, with some farms in Otago and Waikato also required to have Farm Environment Plans in place. The plans require farmers to manage environmental risks around activities such as farm dairy effluent, erosion, discharges into waterways (through planting and fencing intensively stocked areas), irrigation and

1845-701: A whole is 2.1 m (6 ft 11 in). In mountain portions of the West Coast, it exceeds 10 m per year. The distribution of precipitation across the country is determined by its location with the mid-southern latitudes and its topography. Seasonal differences in precipitation are substantial, regularly leading to summer water deficits in many parts of the country, though the season of greatest and least precipitation differ from region to region. The amount of precipitation also varies interannually in response to both El Niño–Southern Oscillation and Interdecadal Pacific Oscillation cycles. Water resources are used for

1968-490: A yearly average of more than 2,000 hours of sunshine. The southern and southwestern parts of the South Island have a cooler and cloudier climate, with around 1,400–1,600 hours; the northern and northeastern parts of the South Island are the sunniest areas of the country and receive about 2,400–2,500 hours. The general snow season is early June until early October, though cold snaps can occur outside this season. Snowfall

2091-603: Is Wellington , and its most populous city is Auckland . The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and subsequently developed a distinctive Māori culture . In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1769 the British explorer Captain James Cook became

2214-400: Is 145 million litres per person. The reliable supply of good water is an important economic advantage for New Zealand, but its quality and availability is declining. There are 3,820 lakes in New Zealand with a surface area larger than 1 hectare (2.5 acres), and are of varying types and origins. Many of the lakes in the central North Island area are volcanic crater lakes, while the majority of

2337-617: Is a constitutional monarchy with a parliamentary democracy , although its constitution is not codified . Charles III is the King of New Zealand and thus the head of state . The king is represented by the governor-general , whom he appoints on the advice of the prime minister . The governor-general can exercise the Crown 's prerogative powers , such as reviewing cases of injustice and making appointments of ministers , ambassadors, and other key public officials, and in rare situations,

2460-743: Is a member of the United Nations , the Commonwealth of Nations and the Organisation for Economic Co-operation and Development (OECD), and participates in the Five Power Defence Arrangements . Today, New Zealand enjoys particularly close relations with the United States and is one of its major non-NATO allies , as well as with Australia , with a " Trans-Tasman " identity between citizens of

2583-593: Is also a significant source of revenue. New Zealand is a member of the United Nations , Commonwealth of Nations , ANZUS , UKUSA , Five Eyes , OECD , ASEAN Plus Six , Asia-Pacific Economic Cooperation , the Pacific Community and the Pacific Islands Forum . It enjoys particularly close relations with the United States and is one of its major non-NATO allies ; the United Kingdom; Samoa , Fiji , and Tonga ; and with Australia , with

2706-480: Is also consistent with a much debated questionable third line of oral evidence, traditional genealogies ( whakapapa ) which point to around 1350 as a probable arrival date for many of the founding canoes ( waka ) from which many Māori trace their descent. Some Māori later migrated to the Chatham Islands where they developed their distinct Moriori culture. A later 1835 invasion by Māori resulted in

2829-495: Is an aggregate of water trends in the regions and it shows no trends in water quality improvement or the related issue of water abstraction. However, there are observed improvements in water quality for some water bodies in some cases. The Tarawera River , nicknamed "the black drain", has had a history of water pollution, predominantly due to industrial activity. In 2009, the Tasman Mill gained permission to continue polluting

2952-441: Is becoming an increasing concern for environmentalists and for regulatory bodies. An increase in dairy farming is linked to an increase in water pollution, and siltation due to land clearance has affected lakes, rivers, caves and bays. There are more than 800 water quality monitoring sites around New Zealand that are regularly sampled. Various organisations in New Zealand are involved with water and its use. Regional Councils have

3075-599: Is changing sedimentation patterns and increasing organic bed loads and deposition in NZ lakes and shallow coastal waters. Since 2005 increased dairy farming rates of grazing animals have outstripped riparian planting and the ability of some Regional Councils to manage and mitigate impacts on the quality of water, and there is some evidence of urea use leading to nitrogen levels in waterways. Horticulture , arable farming and plantation forestry generally have less effect than dairy farming . In 2001 Fish and Game New Zealand started

3198-582: Is classified as a non-self-governing territory , but is administered by a council of three elders (one from each Tokelauan atoll ). The Ross Dependency is New Zealand's territorial claim in Antarctica , where it operates the Scott Base research facility. New Zealand nationality law treats all parts of the realm equally, so most people born in New Zealand, the Cook Islands, Niue, Tokelau, and

3321-869: Is common in the eastern and southern parts of the South Island and mountain areas across the country. New Zealand's geographic isolation for 80 million years and island biogeography has influenced evolution of the country's species of animals , fungi and plants . Physical isolation has caused biological isolation, resulting in a dynamic evolutionary ecology with examples of distinctive plants and animals as well as populations of widespread species. The flora and fauna of New Zealand were originally thought to have originated from New Zealand's fragmentation off from Gondwana, however more recent evidence postulates species resulted from dispersal. About 82% of New Zealand's indigenous vascular plants are endemic , covering 1,944 species across 65 genera . The number of fungi recorded from New Zealand, including lichen-forming species,

3444-466: Is equivalent to 15% of the population of New Zealand. New Zealand has a strong presence among the Pacific Island countries, and enjoys strong diplomatic relations with Samoa , Fiji , and Tonga , and among smaller nations. A large proportion of New Zealand's aid goes to these countries, and many Pacific people migrate to New Zealand for employment. The increase of this since the 1960s led to

3567-440: Is heavily dependent on international trade, particularly in agricultural products. Exports account for 24% of its output, making New Zealand vulnerable to international commodity prices and global economic slowdowns . Food products made up 55% of the value of all the country's exports in 2014; wood was the second largest earner (7%). New Zealand's main trading partners, as at June 2018 , are China ( NZ$ 27.8b), Australia ($ 26.2b),

3690-553: Is made up of two main islands and more than 700 smaller islands . The two main islands (the North Island , or Te Ika-a-Māui , and the South Island , or Te Waipounamu ) are separated by Cook Strait , 22 kilometres (14 mi) wide at its narrowest point. Besides the North and South Islands, the five largest inhabited islands are Stewart Island (across the Foveaux Strait ), Chatham Island , Great Barrier Island (in

3813-502: Is mainly derived from Māori and early British settlers, with recent broadening of culture arising from increased immigration to the country . The official languages are English, Māori , and New Zealand Sign Language , with the local dialect of English being dominant. A developed country , it was the first to introduce a minimum wage , and the first to give women the right to vote . It ranks very highly in international measures of quality of life , human rights , and it has one of

3936-436: Is not known, nor is the proportion of those fungi which are endemic, but one estimate suggests there are about 2,300 species of lichen-forming fungi in New Zealand and 40% of these are endemic. The two main types of forest are those dominated by broadleaf trees with emergent podocarps , or by southern beech in cooler climates. The remaining vegetation types consist of grasslands, the majority of which are tussock . Before

4059-568: Is organised into 11 regional councils and 67 territorial authorities for local government purposes. The Realm of New Zealand also includes Tokelau (a dependent territory ); the Cook Islands and Niue (self-governing states in free association with New Zealand); and the Ross Dependency , which is New Zealand's territorial claim in Antarctica . The first European visitor to New Zealand, Dutch explorer Abel Tasman , named

4182-603: Is slow, the Department of Conservation have sewerage holding tanks on the toilets at backcountry huts . The sewerage is flown out by helicopter for treatment elsewhere. Freedom camping , a popular activity in some areas, is suspected of causing water pollution due to the incorrect disposal of human waste. The most significant source of water pollution in urban areas is due to sewerage . Broken sewers and faulty connections allow sewerage to enter stormwater systems. Also, during flooding sewerage pumping stations are inundated with

4305-458: Is that, whether or not some settlers arrived before 1314, the main settlement period was in the subsequent decades, possibly involving a coordinated mass migration. It is also the broad consensus of historians that the Polynesian settlement of New Zealand was planned and deliberate. Over the centuries that followed, the settlers developed a distinct culture now known as Māori. This scenario

4428-515: Is the region with New Zealand's most polluted waterways, with 62% of rivers and lakes graded poor by the Ministry for the Environment for swimming, and 0% of rivers and lakes graded as good. In 2018, waterways across New Zealand have been showing improvements across a number of water quality measures, as monitored by LAWA data. Water pollution in New Zealand has several negative impacts on

4551-519: Is to regulate "the natural environment with particular emphasis on resource management ", while territorial authorities are responsible for sewage, water, local roads, building consents, and other local matters. Five of the territorial councils are unitary authorities and also act as regional councils. The territorial authorities consist of 13 city councils, 53 district councils, and the Chatham Islands Council. While officially

4674-416: Is under pressure from agriculture, hydropower, urban development, pest invasions and climate change . While pollution from point sources has been reduced, diffuse pollution such as nutrients, pathogens and sediments development and from stormwater in towns is not under control. There are more than 800 water quality monitoring sites around New Zealand that are regularly sampled. As of January 2019 , Auckland

4797-635: The 1973 oil and 1979 energy crises, led to a severe economic depression . Living standards in New Zealand fell behind those of Australia and Western Europe, and by 1982 New Zealand had the lowest per-capita income of all the developed nations surveyed by the World Bank . In the mid-1980s New Zealand deregulated its agricultural sector by phasing out subsidies over a three-year period. Since 1984, successive governments engaged in major macroeconomic restructuring (known first as Rogernomics and then Ruthanasia ), rapidly transforming New Zealand from

4920-872: The ANZAC tradition it shares with Australia. In addition to Vietnam and the two world wars, New Zealand fought in the Second Boer War , the Korean War , the Malayan Emergency , the Gulf War , and the Afghanistan War . It has contributed forces to several regional and global peacekeeping missions, such as those in Cyprus , Somalia , Bosnia and Herzegovina , the Sinai , Angola , Cambodia ,

5043-685: The European Union ($ 22.9b), the United States ($ 17.6b), and Japan ($ 8.4b). On 7 April 2008, New Zealand and China signed the New Zealand–China Free Trade Agreement , the first such agreement China has signed with a developed country. In July 2023, New Zealand and the European Union entered into the EU–New Zealand Free Trade Agreement , which eliminated tariffs on several goods traded between

5166-725: The Gondwanan supercontinent. About 25 million years ago, a shift in plate tectonic movements began to contort and crumple the region. This is now most evident in the Southern Alps, formed by compression of the crust beside the Alpine Fault . Elsewhere, the plate boundary involves the subduction of one plate under the other, producing the Puysegur Trench to the south, the Hikurangi Trough east of

5289-621: The Great Depression . The depression led to the election of the first Labour Government and the establishment of a comprehensive welfare state and a protectionist economy. New Zealand experienced increasing prosperity following the Second World War, and Māori began to leave their traditional rural life and move to the cities in search of work. A Māori protest movement developed, which criticised Eurocentrism and worked for greater recognition of Māori culture and of

New Zealand is long and narrow—over 1,600 kilometres (990 mi) along its north-north-east axis with a maximum width of 400 kilometres (250 mi) —with about 15,000 km (9,300 mi) of coastline and a total land area of 268,000 square kilometres (103,500 sq mi). Because of its far-flung outlying islands and long coastline,

5535-522: The Iran–Iraq border, Bougainville , East Timor , and the Solomon Islands . New Zealand has an advanced market economy , ranked 13th in the 2021 Human Development Index , and fourth in the 2022 Index of Economic Freedom . It is a high-income economy with a nominal gross domestic product (GDP) per capita of US$ 36,254. The currency is the New Zealand dollar , informally known as

5658-584: The Legislative Council , until this was abolished in 1950. The supremacy of parliament over the Crown and other government institutions was established in England by the Bill of Rights 1689 and has been ratified as law in New Zealand. The House of Representatives is democratically elected, and a government is formed from the party or coalition with the majority of seats. If no majority is formed,

5781-720: The Local Government Act 2002 and the Resource Management Act 1991 . The Resource Management Act 1991 governs the use of water (and other natural resources). A resource consent is required for taking, damming, discharging and diverting water. There is a National Policy Statement for Freshwater Management. In modern times, the quantity, quality and timing of water within New Zealand has been changing. Principal causes have been abstraction, impoundment, land use and land cover change, and agricultural and industrial runoff. Water pollution in New Zealand

5904-532: The South Island ( Te Waipounamu )—and over 700 smaller islands . It is the sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia , Fiji , and Tonga . The country's varied topography and sharp mountain peaks, including the Southern Alps , owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city

6027-691: The Statute of Westminster , confirming that the British Parliament could no longer legislate for the country without its consent. The British government's residual legislative powers were later removed by the Constitution Act 1986 , and final rights of appeal to British courts were abolished in 2003. Early in the 20th century , New Zealand was involved in world affairs, fighting in the First and Second World Wars and suffering through

6150-632: The Tui River , a tributary of the Mangatainoka River , and is applying for resource consents to continue doing so. The Tasman Pulp and Paper Mill , now owned by Norske Skog , has been discharging waste into the Tarawera River since 1955. High numbers of visitors to parks and other areas where there are no toilets is increasing the chance of pollution from human waste . In alpine areas, where anaerobic digestion of fecal matter

6273-675: The United Kingdom and negotiate a treaty with the Māori. The Treaty of Waitangi was first signed in the Bay of Islands on 6 February 1840. In response to the New Zealand Company's attempts to establish an independent settlement in Wellington , Hobson declared British sovereignty over all of New Zealand on 21 May 1840, even though copies of the treaty were still circulating throughout the country for Māori to sign. With

6396-624: The United States Department of State noted that the New Zealand government generally respected the rights of individuals, but voiced concerns regarding the social status of the Māori population. In terms of structural discrimination , the New Zealand Human Rights Commission has asserted that there is strong, consistent evidence that it is a real and ongoing socioeconomic issue. One example of structural inequality in New Zealand can be seen in

6519-534: The Waikato River is one such waterfall. Sutherland Falls is usually regarded as the highest waterfall in New Zealand at 580 metres high but Browne Falls cascades 619 m or 836 m depending on what is considered to be the source. The Maruia Falls on the Maruia River are a relatively new waterfall formed as a result of the 1929 Murchison earthquake . The average annual precipitation for New Zealand as

6642-641: The West Coast of the South Island to semi-arid in Central Otago and the Mackenzie Basin of inland Canterbury and subtropical in Northland . Of the seven largest cities, Christchurch is the driest, receiving on average only 618 millimetres (24.3 in) of rain per year and Wellington the wettest, receiving almost twice that amount. Auckland, Wellington and Christchurch all receive

6765-413: The alienation and confiscation of large amounts of Māori land. New Zealand became a dominion in 1907; it gained full statutory independence in 1947, retaining the monarch as head of state . Today, the majority of New Zealand's population of 5.25 million is of European descent ; the indigenous Māori are the largest minority, followed by Asians and Pasifika . Reflecting this, New Zealand's culture

6888-424: The caldera of one of the world's most active supervolcanoes . New Zealand is prone to earthquakes . The country owes its varied topography, and perhaps even its emergence above the waves, to the dynamic boundary it straddles between the Pacific and Indo-Australian Plates . New Zealand is part of Zealandia , a microcontinent nearly half the size of Australia that gradually submerged after breaking away from

7011-430: The reserve powers (e.g. the power to dissolve Parliament or refuse the royal assent of a bill into law). The powers of the monarch and the governor-general are limited by constitutional constraints, and they cannot normally be exercised without the advice of ministers. The New Zealand Parliament holds legislative power and consists of the king and the House of Representatives . It also included an upper house,

7134-420: The resource consent prosecution may result. To limit sediment run-off during earthworks straw bales and stormwater settling ponds are used. These are completely inadequate in high rainfall events where the interceptors are overwhelmed and silt laden waters flow into streams and rivers. Regional councils have the responsibility to address water use and misuse issues as set out in the Resource Management Act ,

7257-444: The seven-continent model. New Zealand's climate is predominantly temperate maritime ( Köppen : Cfb), with mean annual temperatures ranging from 10 °C (50 °F) in the south to 16 °C (61 °F) in the north. Historical maxima and minima are 42.4 °C (108.32 °F) in Rangiora , Canterbury and −25.6 °C (−14.08 °F) in Ranfurly , Otago . Conditions vary sharply across regions from extremely wet on

7380-446: The "Kiwi dollar"; it also circulates in the Cook Islands (see Cook Islands dollar ), Niue, Tokelau, and the Pitcairn Islands . Historically, extractive industries have contributed strongly to New Zealand's economy, focusing at different times on sealing, whaling, flax , gold, kauri gum , and native timber. The first shipment of refrigerated meat on the Dunedin in 1882 led to the establishment of meat and dairy exports to Britain,

7503-629: The 2024 Global Peace Index , New Zealand is the 4th most peaceful country in the world. New Zealand's military services—the New Zealand Defence Force —comprise the New Zealand Army , the Royal New Zealand Air Force , and the Royal New Zealand Navy . New Zealand's national defence needs are modest since a direct attack is unlikely. However, its military has had a global presence . The country fought in both world wars, with notable campaigns in Gallipoli , Crete , El Alamein , and Cassino . The Gallipoli campaign played an important part in fostering New Zealand's national identity and strengthened

Fonterra exports the majority of its produce, and encourages farmers to limit environmental impacts as a method of getting environmentally aware consumers to purchase their products. The increase in research into sustainable farming and reducing fertilizer use, increasing the planting of native shrubs, grasses, flaxes and trees along the margins of streams. These techniques help intercept run off of manure, sediments and fertilizer and use them to enhance growth of

7749-492: The Cawthorne Institute showing waterway quality is now improving for many water quality measures based on an analysis of LAWA sites. Urban runoff is polluted with detergents, waste oil, litter and fecal matter. Some stormwater drains have a fish logo painted on the curb to highlight stormwater pollution. Industrial processing frequently involves the discharge of process waste-water to waterways. For example, Fonterra has been discharging wastewater containing milk condensate into

7872-597: The Chatham Islands Council is not a unitary authority, it undertakes many functions of a regional council. The Realm of New Zealand, one of 15 Commonwealth realms , is the entire area over which the king or queen of New Zealand is sovereign and comprises New Zealand, Tokelau , the Ross Dependency , the Cook Islands , and Niue . The Cook Islands and Niue are self-governing states in free association with New Zealand. The New Zealand Parliament cannot pass legislation for these countries, but with their consent can act on behalf of them in foreign affairs and defence. Tokelau

7995-424: The Government as a major societal issue; the country has 12.0% of children living in low-income households that had less than 50% of the median equivalised disposable household income as of June 2022 . Poverty has a disproportionately high effect in ethnic-minority households, with a quarter (23.3%) of Māori children and almost a third (28.6%) of Pacific Islander children living in poverty as of 2020 . New Zealand

8118-410: The MMP system, each person has two votes; one is for a candidate standing in the voter's electorate , and the other is for a party. Based on the 2018 census data, there are 72 electorates (which include seven Māori electorates in which only Māori can optionally vote), and the remaining 48 of the 120 seats are assigned so that representation in Parliament reflects the party vote, with the threshold that

8241-553: The Māori of later years. According to an early European synthesized interpretation of various Māori traditional accounts, around 750 CE the heroic explorer, Kupe , had discovered New Zealand and later, around 1350, one great fleet of settlers set out from Hawaiki in eastern Polynesia. However, from the late 20th century, this story has been increasingly relegated to the realm of legend and myth. An alternative view has emerged from fresh archaeological and scientific evidence, which correlates with doubts raised by historians everywhere as to

8364-426: The North Island, and the Kermadec and Tonga Trenches further north. New Zealand, together with Australia, is part of a wider region known as Australasia . It also forms the southwestern extremity of the geographic and ethnographic region called Polynesia . Oceania is a wider region encompassing the Australian continent , New Zealand, and various island countries in the Pacific Ocean that are not included in

8487-489: The North Island, saw thousands of imperial troops and the Royal Navy come to New Zealand and became known as the New Zealand Wars . Following these armed conflicts, large areas of Māori land were confiscated by the government to meet settler demands. The colony gained a representative government in 1852 , and the first Parliament met in 1854. In 1856 the colony effectively became self-governing, gaining responsibility over all domestic matters (except native policy, which

8610-565: The Ross Dependency are New Zealand citizens. During the period of the New Zealand colony, Britain was responsible for external trade and foreign relations. The 1923 and 1926 Imperial Conferences decided that New Zealand should be allowed to negotiate its own political treaties , and the first commercial treaty was ratified in 1928 with Japan. On 3 September 1939, New Zealand allied itself with Britain and declared war on Germany with Prime Minister Michael Joseph Savage proclaiming, "Where she goes, we go; where she stands, we stand". In 1951,

8733-420: The Tarawera eruption except for three of a decade or so earlier. Radiocarbon dating and pollen evidence of widespread forest fires shortly before the eruption might also indicate a pre-eruption human presence. Additionally, mitochondrial DNA variability within the Māori populations suggest that Eastern Polynesians first settled the New Zealand archipelago between 1250 and 1300, Therefore, current opinion

8856-470: The Treaty of Waitangi. In 1975, a Waitangi Tribunal was set up to investigate alleged breaches of the Treaty, and it was enabled to investigate historic grievances in 1985. The government has negotiated settlements of these grievances with many iwi, although Māori claims to the foreshore and seabed proved controversial in the 2000s. New Zealand is located near the centre of the water hemisphere and

8979-659: The United Kingdom became increasingly focused on its European interests, while New Zealand joined Australia and the United States in the ANZUS security treaty. The influence of the United States on New Zealand weakened following protests over the Vietnam War , the refusal of the United States to admonish France after the sinking of the Rainbow Warrior , disagreements over environmental and agricultural trade issues, and New Zealand's nuclear-free policy . Despite

9102-524: The United States's suspension of ANZUS obligations, the treaty remained in effect between New Zealand and Australia, whose foreign policy has followed a similar historical trend. Close political contact is maintained between the two countries, with free trade agreements and travel arrangements that allow citizens to visit, live and work in both countries without restrictions. In 2013 there were about 650,000 New Zealand citizens living in Australia, which

9225-476: The Waikato and Canterbury were identified as being in relatively poor condition. Sediment from erosion of hills and river banks is also a source of pollution of waters. The sediments loading from high intensity, increasing frequency storm and high rainfall events has led to millions of tonnes of sediment changing fluvial systems in NZ waterways. This sediment contains high organic contents from forest litter which

9348-762: The application of nutrients. Some councils have also imposed nutrient limits on farmers. In 2016, a controversial video by Greenpeace highlighted the contribution of dairy farming to river pollution, stating that over 60 percent of monitored rivers are unsafe to swim in. This video advertisement was appealed by DairyNZ, but the Advertising Standards Authority found in favour of Greenpeace. The changes to introduce stricter environmental controls on farmers have been cited as contributing to recent trends showing waterway improvements by Horizons Regional Council and Environment Canterbury. They have also been cited as contributing to analysis completed by

9471-438: The arrival of humans, an estimated 80% of the land was covered in forest, with only high alpine , wet, infertile and volcanic areas without trees. Massive deforestation occurred after humans arrived, with around half the forest cover lost to fire after Polynesian settlement. Much of the remaining forest fell after European settlement, being logged or cleared to make room for pastoral farming, leaving forest occupying only 23% of

9594-509: The canal (sparked initially by Ngāti Awa campaigner Joe Harawira ) received international recognition in 2019. Historically much of Canterbury has been dry land and arable farming but there has been a huge increase in dairy farming in the region. Dairy farming in Canterbury requires large amounts of irrigation since the average rainfall is too low to support dairy cow pastures. The Ōpāwaho / Heathcote River has been subjected to

9717-474: The consequences of these decisions. The 42nd and current prime minister, since 27 November 2023, is Christopher Luxon . A parliamentary general election must be called no later than three years after the previous election. Almost all general elections between 1853 and 1993 were held under the first-past-the-post voting system. Since the 1996 election , a form of proportional representation called mixed-member proportional (MMP) has been used. Under

9840-493: The country at 850 long-term water monitoring sites across 650,000 river segments, 961 lakes and 419 estuaries. It found that almost every region in New Zealand exceeded bottom line levels in one or more contaminants. More than three quarters of land in the country was contributing too much E. coli to fresh water, and agricultural land had excessive nitrogen loads, with Southland needing to reduce its nitrate pollution by 41 percent and Canterbury by 44 percent. The above table

9963-461: The country has extensive marine resources. Its exclusive economic zone is one of the largest in the world, covering more than 15 times its land area. The South Island is the largest landmass of New Zealand. It is divided along its length by the Southern Alps . There are 18 peaks over 3,000 metres (9,800 ft), the highest of which is Aoraki / Mount Cook at 3,724 metres (12,218 ft). Fiordland 's steep mountains and deep fiords record

10086-502: The criminal justice system. According to the Ministry of Justice , Māori are overrepresented, comprising 45% of New Zealanders convicted of crimes and 53% of those imprisoned, while only being 16.5% of the population. The early European settlers divided New Zealand into provinces , which had a degree of autonomy. Because of financial pressures and the desire to consolidate railways, education, land sales, and other policies, government

10209-690: The early 19th century, Christian missionaries began to settle New Zealand, eventually converting most of the Māori population. The Māori population declined to around 40% of its pre-contact level during the 19th century; introduced diseases were the major factor. The British Government appointed James Busby as British Resident to New Zealand in 1832. His duties, given to him by Governor Bourke in Sydney, were to protect settlers and traders "of good standing", prevent "outrages" against Māori, and apprehend escaped convicts. In 1835, following an announcement of impending French settlement by Charles de Thierry ,

10332-520: The environment, economy, and public health. Some of these impacts include: Guideline standards for water quality are published by MfE. Agriculture is a major use of lowland areas of New Zealand and has affected water quality. The expansion of intensive dairy production has resulted in greater levels of nitrogen in soil, surface and groundwater. In 1993, the National Institute of Water and Atmospheric Research summarised available data on

10455-405: The extensive ice age glaciation of this southwestern corner of the South Island. The North Island is less mountainous but is marked by volcanism . The highly active Taupō Volcanic Zone has formed a large volcanic plateau , punctuated by the North Island's highest mountain, Mount Ruapehu (2,797 metres (9,177 ft)). The plateau also hosts the country's largest lake, Lake Taupō , nestled in

10578-483: The fifteen sites tested meeting the standards for swimmability. The Waikato has had a long history of dairy farming and has some of the most productive soils in the country. Water quality, especially as shown by the indicators of conductivity and pH , in the Waikato region is deteriorating. The Waikato River has a high level of pollution due to various point and non-point sources . The West Coast receives

10701-513: The first European to set foot on and map New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs signed the Treaty of Waitangi which paved the way for Britain's declaration of sovereignty later that year and the establishment of the Crown Colony of New Zealand in 1841. Subsequently, a series of conflicts between the colonial government and Māori tribes resulted in

10824-476: The floodwaters and sewerage is released. Water run-off from roads contains pollutants such as zinc, copper, lead and hydrocarbons from vehicle wear, vehicle emissions and from the road surface itself. Urban areas have large amounts of paved surface therefore there is a higher likelihood that water contaminated with organic matter will not be filtered through soils. Sediment run-off from exposed soils in new subdivisions does occur and if it occurs due to breaches of

10947-491: The formation of the Pasifika New Zealander pan-ethnic group, the fourth-largest ethnic grouping in the country. Permanent migration is regulated under the 1970 Samoan Quota Scheme and the 2002 Pacific Access Category, which allow up to 1,100 Samoan nationals and up to 750 other Pacific Islanders respectively to become permanent New Zealand residents each year. A seasonal workers scheme for temporary migration

11070-457: The high-profile dirty dairying campaign to highlight the effect of pollution from farming intensification on the ecological health of freshwater environments. As a reaction to this campaign Fonterra , the largest dairy company in New Zealand, along with a number of government agencies instigated the Dairying and Clean Streams Accord to address water pollution due to dairy farming. The aim of

11193-468: The introduction of these new rules, waterways are now showing improvement s across a number of measures. In Southland effluent from dairy sheds used for more than 50 cows needs a resource consent . Environment Southland recommends effluent is spread at a rate of eight hectares per 100 cows and should not applied to wet soils. In 2012, Otago Regional Council carried out 19 prosecutions for incidents of pollution, twice as many as in 2011. The majority of

11316-610: The islands Staten Land , believing they were part of the Staten Landt that Jacob Le Maire had sighted off the southern end of South America. Hendrik Brouwer proved that the South American land was a small island in 1643, and Dutch cartographers subsequently renamed Tasman's discovery Nova Zeelandia from Latin , after the Dutch province of Zeeland . This name was later anglicised to New Zealand . This

11439-447: The islands North (North Island), Middle (South Island), and South ( Stewart Island / Rakiura ). In 1830, mapmakers began to use "North" and "South" on their maps to distinguish the two largest islands, and by 1907, this was the accepted norm. The New Zealand Geographic Board discovered in 2009 that the names of the North Island and South Island had never been formalised, and names and alternative names were formalised in 2013. This set

11562-580: The islands are uninhabited except for about six people at Raoul Island station. These islands put the northern border of New Zealand at 29 degrees South latitude. After the 1982 UNCLOS , the islands contributed significantly to New Zealand's exclusive economic zone . In 1891, the Liberal Party came to power as the first organised political party. The Liberal Government , led by Richard Seddon for most of its period in office, passed many important social and economic measures. In 1893, New Zealand

11685-436: The judiciary to interpret the law based solely on the legislation enacted by Parliament without other influences on their decisions. New Zealand is identified as one of the world's most stable and well-governed states. As of 2017, the country was ranked fourth in the strength of its democratic institutions, and first in government transparency and lack of corruption . LGBT rights in the nation are also recognised as among

11808-718: The lakes near the Southern Alps were carved by glaciers. Hydroelectric reservoirs are common in South Canterbury, Central Otago and along the Waikato River. Over 180,000 km (110,000 mi) of rivers has been mapped in New Zealand, the longest being the Waikato River with a length of 425 kilometres and the largest river by volume is the Clutha River with a mean discharge of 614 cubic metres per second. New Zealand has many notable waterfalls , some of which are regularly visited by tourists. Huka Falls on

11931-511: The land in 1997. The forests were dominated by birds , and the lack of mammalian predators led to some like the kiwi , kākāpō , weka and takahē evolving flightlessness . The arrival of humans, associated changes to habitat, and the introduction of rats , ferrets and other mammals led to the extinction of many bird species, including large birds like the moa and Haast's eagle . Other indigenous animals are represented by reptiles ( tuatara , skinks and geckos ), frogs , such as

12054-641: The latter being common. New Zealand is a member of the Five Eyes intelligence sharing agreement, known formally as the UKUSA Agreement . The five members of this agreement compromise the core Anglosphere : Australia, Canada, New Zealand, the United Kingdom, and the United States. Since 2012, New Zealand has had a partnership arrangement with NATO under the Partnership Interoperability Initiative. According to

12177-589: The longest recession in over thirty years, and unemployment rising back to 7% in late 2009. The lowest unemployment rate recorded using the current methodology was in December 2021 during the COVID-19 pandemic , at 3.2%. Unemployment rates for different age groups follow similar trends but are consistently higher among youth. During the September 2021 quarter, the general unemployment rate was around 3.2%, while

12300-456: The lowest levels of perceived corruption in the world. It retains visible levels of inequality , having structural disparities between its Māori and European populations. New Zealand underwent major economic changes during the 1980s, which transformed it from a protectionist to a liberalised free-trade economy. The service sector dominates the national economy , followed by the industrial sector, and agriculture ; international tourism

12423-455: The massacre and virtual extinction of the Moriori. In a hostile 1642 encounter between Ngāti Tūmatakōkiri and Dutch explorer Abel Tasman 's crew, four of Tasman's crew members were killed, and at least one Māori was hit by canister shot . Europeans did not revisit New Zealand until 1769, when British explorer James Cook mapped almost the entire coastline. Following Cook, New Zealand

12546-485: The most tolerant in Oceania . New Zealand ranks highly for civic participation in the political process, with 82% voter turnout during recent general elections, compared to an OECD average of 69%. However, this is untrue for local council elections; a historically low 36% of eligible New Zealanders voted in the 2022 local elections , compared with an already low 42% turnout in 2019 . A 2017 human rights report by

12669-583: The names as North Island or Te Ika-a-Māui , and South Island or Te Waipounamu . For each island, either its English or Māori name can be used, or both can be used together. Similarly the Māori and English names for the whole country are sometimes used together ( Aotearoa New Zealand ); however, this has no official recognition. The first people to reach New Zealand were Polynesians in ocean going waka (canoes). Their arrival likely occurred in several waves, approximately between 1280 and 1350 CE. Those Polynesian settlers, isolated in New Zealand, became

12792-719: The nebulous United Tribes of New Zealand sent a Declaration of Independence to King William IV of the United Kingdom asking for protection. Ongoing unrest, the proposed settlement of New Zealand by the New Zealand Company (which had already sent its first ship of surveyors to buy land from Māori) and the dubious legal standing of the Declaration of Independence prompted the Colonial Office to send Captain William Hobson to claim sovereignty for

12915-475: The number of dairy cows doubling between 1990 and 2007, to become New Zealand's largest export earner. In the year to June 2018, dairy products accounted for 17.7% ($ 14.1 billion) of total exports, and the country's largest company, Fonterra , controls almost one-third of the international dairy trade. Other exports in 2017–18 were meat (8.8%), wood and wood products (6.2%), fruit (3.6%), machinery (2.2%) and wine (2.1%). New Zealand's wine industry has followed

13038-448: The planted zones. Fencing off streams and riparian planting has been shown to improve water quality, though this is more effective at reducing pollution from surface runoff (such as from phosphorus) rather than contaminants such as nitrogen which reach the waterway by seeping through the soil. Fencing prevent stock from depositing feces directly into waterways and trampling the banks; planting reduces surface runoff. One study of fencing

13161-711: The pollution incidents were of dairy effluent. In Taranaki , there are 1400 dairy sheds where the dairy effluent drains into streams instead of being sprayed to land, according to data from Taranaki Regional Council's 2012 State of the Environment report. In 2012, the president of the New Zealand Freshwater Sciences Society expressed surprise at the number of consented dairy discharges to streams, given most other regional councils prosecute dairy farmers who allow dairy effluent to enter waterways. In 2019, Taranaki Regional Council reported that freshwater quality had deteriorated, with only two of

13284-442: The protected endangered Hamilton's Frog , spiders , insects ( wētā ), and snails. Some, such as the tuatara, are so unique that they have been called living fossils . Three species of bats ( one since extinct) were the only sign of native land mammals in New Zealand until the 2006 discovery of bones from a unique, mouse-sized land mammal at least 16 million years old. Marine mammals, however, are abundant, with almost half

13407-474: The quality of water in rivers. They concluded that "Some lowland river reaches in agriculturally developed catchments are in poor condition" reflecting "agriculturally derived diffuse and point source waste inputs in isolation or in addition to urban or industrial waste inputs" . The key contaminants identified in lowland rivers were dissolved inorganic nitrogen, dissolved reactive phosphorus, sediment and coliforms. Small streams in some dairy farming areas such as

13530-575: The reliability of interpretations drawn from the oral evidence of indigenous peoples, including from Māori. Regarding the arrival of these Polynesian settlers, there are no human remains, artefacts or structures which are confidently dated to earlier than the Kaharoa Tephra, a layer of volcanic debris deposited by the Mount Tarawera eruption around 1314 CE. Samples of rat bone, rat-gnawed shells and seed cases have given dates later than

13653-714: The river for the next 25 years. Between 1950 and 1989, the Whakatane Sawmill dumped contaminated sawdust, bark, scrap timber, and chemicals in and around Whakatane and the Rangitaiki Plains , including the Kopeopeo Canal , which has been called New Zealand's most polluted waterway. These wastes came from the timber treatment mill, where PCP had been used as a wood preservative. The PCP was contaminated with dioxin and furan (PCDD/PCDFs), resulting in dioxin-contaminated sediment. Remediation efforts on

13776-594: The signing of the treaty and declaration of sovereignty, the number of immigrants, particularly from the United Kingdom, began to increase. New Zealand was administered as a dependency of the Colony of New South Wales until becoming a separate Crown colony , the Colony of New Zealand , on 3 May 1841. Armed conflict began between the colonial government and Māori in 1843 with the Wairau Affray over land and disagreements over sovereignty. These conflicts, mainly in

13899-472: The statutory responsibility for water. Water pollution in New Zealand Water pollution in New Zealand is an increasing concern for those who use and care for waterways and for New Zealand regulatory bodies. An increase in population is linked to an increase in water pollution , due to a range of causes such as rural land use, industrial use and urban development. Fresh water quality

14022-467: The total workforce in 2016. In 2017, international visitor arrivals were expected to increase at a rate of 5.4% annually up to 2022. Wool was New Zealand's major agricultural export during the late 19th century. Even as late as the 1960s it made up over a third of all export revenues, but since then its price has steadily dropped relative to other commodities, and wool is no longer profitable for many farmers. In contrast, dairy farming increased, with

14145-486: The two regions. This free trade agreement expanded on the pre-existing free trade agreement and saw a reduction in tariffs on meat and dairy in response to feedback from the affected industries. The service sector is the largest sector in the economy, followed by manufacturing and construction and then farming and raw material extraction. Tourism plays a significant role in the economy, contributing $ 12.9 billion (or 5.6%) to New Zealand's total GDP and supporting 7.5% of

14268-481: The unemployment rate for youth aged 15 to 24 was 9.2%. New Zealand has experienced a series of " brain drains " since the 1970s that still continue today. Nearly one-quarter of highly skilled workers live overseas, mostly in Australia and Britain, which is the largest proportion from any developed nation. In recent decades, however, a " brain gain " has brought in educated professionals from Europe and less developed countries. Today New Zealand's economy benefits from

14391-847: The world's cetaceans (whales, dolphins, and porpoises ) and large numbers of fur seals reported in New Zealand waters. Many seabirds breed in New Zealand, a third of them unique to the country. More penguin species are found in New Zealand than in any other country, with 13 of the world's 18 penguin species. Since human arrival, almost half of the country's vertebrate species have become extinct, including at least fifty-one birds, three frogs, three lizards, one freshwater fish, and one bat. Others are endangered or have had their range severely reduced. However, New Zealand conservationists have pioneered several methods to help threatened wildlife recover, including island sanctuaries, pest control, wildlife translocation, fostering, and ecological restoration of islands and other protected areas . New Zealand

14514-569: Was centralised and the provinces were abolished in 1876. The provinces are remembered in regional public holidays and sporting rivalries. Since 1876, various councils have administered local areas under legislation determined by the central government. In 1989, the government reorganised local government into the current two-tier structure of regional councils and territorial authorities . The 249 municipalities that existed in 1975 have now been consolidated into 67 territorial authorities and 11 regional councils. The regional councils' role

14637-472: Was granted in the mid-1860s). Following concerns that the South Island might form a separate colony, premier Alfred Domett moved a resolution to transfer the capital from Auckland to a locality near Cook Strait . Wellington was chosen for its central location, with Parliament officially sitting there for the first time in 1865. In 1886, New Zealand annexed the volcanic Kermadec Islands , about 1,000 km (620 mi) northeast of Auckland. Since 1937,

14760-615: Was introduced in 2007, and in 2009 about 8,000 Pacific Islanders were employed under it. New Zealand is involved in the Pacific Islands Forum , the Pacific Community , Asia-Pacific Economic Cooperation , and the Association of Southeast Asian Nations Regional Forum (including the East Asia Summit ). New Zealand has been described as a middle power in the Asia-Pacific region, and an emerging power . The country

14883-584: Was the first nation in the world to grant all women the right to vote and pioneered the adoption of compulsory arbitration between employers and unions in 1894. The Liberals also guaranteed a minimum wage in 1894, a world first. In 1907, at the request of the New Zealand Parliament, King Edward VII proclaimed New Zealand a Dominion within the British Empire , reflecting its self-governing status. In 1947, New Zealand adopted

15006-528: Was visited by numerous European and North American whaling , sealing , and trading ships. They traded European food, metal tools, weapons, and other goods for timber, Māori food, artefacts, and water. The introduction of the potato and the musket transformed Māori agriculture and warfare. Potatoes provided a reliable food surplus, which enabled longer and more sustained military campaigns. The resulting intertribal Musket Wars encompassed over 600 battles between 1801 and 1840, killing 30,000–40,000 Māori. From

15129-706: Was written as Nu Tireni in the Māori language (spelled Nu Tirani in Te Tiriti o Waitangi). In 1834 a document written in Māori and entitled " He Wakaputanga o te Rangatiratanga o Nu Tireni " was translated into English and became the Declaration of the Independence of New Zealand . It was prepared by Te W(h)akaminenga o Nga Rangatiratanga o Nga Hapu o Nu Tireni , the United Tribes of New Zealand , and
