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

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

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

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,

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),

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.

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
