When the first sections of the NIMT were built, there was great uncertainty as to even the route in Waikato , with Cambridge , Kihikihi , Te Awamutu and Alexandra considered as possible destinations in Waikato. The central section was gradually extended to meet up in 1909, 23 years after
243-651: A 60% majority in November 1954, and the result was predictable given the demographics of the population then living in the area: licensing was carried by a large majority: 80% for European and 25% of Maori in favour of a license. The greater part of the region's economy is involved in farming (especially pastoral farming) and forestry, with some supporting services. There are some areas of tourist significance, such as Waitomo Caves . The King Country also contains areas of conservation estate, especially Pureora Forest Park . From 1966 to 31 March 2010, King Country Radio (with

In 1980 the 1880s Poro-O-Tarao Tunnel in the King Country was replaced by a tunnel with clearances which allowed for large hicube containers. In 2009–10, the 1.5 km (0.93 mi) section of line between Wellington Junction and Distant Junction was rebuilt from double track to triple track, to ease peak-time congestion. In February 2011, duplication between Paekākāriki and Waikanae
405-723: A new eastern route from Auckland to Westfield via Glen Innes and Hobsons Bay, running into the new Auckland railway station and providing better access to the Port of Auckland. The original section between Auckland and Westfield via Newmarket later ceased to be part of the NIMT: Auckland to Newmarket became the Auckland-Newmarket Line , and Newmarket to Westfield became part of the North Auckland Line (NAL) which runs between Whangarei and Westfield. In
486-783: A technical study carried out with assistance from the Japanese Railway Technical Research Institute . The report stated that track capacity would be increased by electrification because such traction is faster and able to move more freight at once. The report stated, for example, that whereas a diesel locomotive could haul 720-tonne trains at 27 km/h (17 mph) up the Raurimu Spiral , an electric locomotive could haul 1100/1200-tonne trains at 45 km/h (28 mph), cutting 3–5 hours off journey times. Less fuel would be needed and employing regenerative braking in electric locomotives lowers

It forms part of two local government regions, Waikato and Manawatū-Whanganui , and all or part of four districts: Ōtorohanga , Ruapehu , Taupō and Waitomo . Taranaki-King Country is a parliamentary electorate for central government. The member represents an area which stretches from the outskirts of New Plymouth City to
648-709: A whole. During the Last Glacial Period when sea levels were over 100 metres lower than present day levels, the North and South islands were connected by a vast coastal plain which formed at the South Taranaki Bight . During this period, most of the North Island was covered in thorn scrubland and forest , while the modern-day Northland Peninsula was a subtropical rainforest . Sea levels began to rise 7,000 years ago, eventually separating
729-517: A year after the last major battle. This line reached Mercer by 20 May 1875, with 29 km (18 mi) from Ngāruawāhia being constructed by the Volunteer Engineer Militia and opened on 13 August 1877. It was extended to Frankton by December 1877, and to Te Awamutu in 1880. An economic downturn stalled construction for the next five years, and Te Awamutu remained the railhead. There were also negotiations with local Māori, and

The Wellington - Longburn (near Palmerston North ) section was constructed between 1881 and 1886 by the Wellington and Manawatu Railway Company (WMR). The company was acquired by the government and merged with the New Zealand Railways Department in 1908. The Longburn to Marton section had been opened on 18 April 1878, as part of

In 1930 the signalling was extended 34 mi 72 ch (56.2 km) to Frankton and the 6 mi 55 ch (10.8 km) from there to Horotiu was doubled. The 3 mi 54 ch (5.9 km) north to Ngāruawāhia was doubled from 5 December 1937, followed by 9 mi 12 ch (14.7 km) Ngāruawāhia to Huntly on 4 December 1938 and Huntly to Ohinewai and Papakura to Paerata in December 1939. By then, wartime shortages delayed further double-tracking. Pokeno to Mercer

However, their plea was ignored, and in 1951 1000 Māori rallied at Tauranganui Pa, Tuakau to protest the laxity in allowing alcohol in their area. In 1951 the National Party was re-elected, and one of its campaign promises was for a single referendum on no-license in the King Country. In 1953 a Bill was introduced for a joint poll requiring

Percentages add to more than 100% as people can identify with more than one ethnicity. Māori form the majority in three districts of the North Island: Kawerau (63.2%), Ōpōtiki (66.2%) and Wairoa (68.5%). Europeans formed
1863-650: The King Country. At this time, the region received a Māori name, Rohe pōtae . This name translates as "Area of the Hat", and is said to have originated when the second Māori King Tāwhiao put his white top hat on a large map of the North Island and declared that all land covered by the hat would be under his mana (or authority). Heavy casualties at the Battle of Gate Pa at Tauranga in April 1864 prompted General Duncan Cameron to abandon plans for further military campaigns in

2025-629: The Minister of Public Works William Hall-Jones instigated a night shift (under kerosene lamps). By the beginning of 1908, there was a 39 km (24 mi) gap between Erua and Ohakune, with a connecting horse-drawn coach service. From Ohakune south to Waiouru, the Public Works Department operated the train, as this section of 27 km (17 mi) had not yet been handed over to the Railways Department. The gap
2106-666: The Ministry of Works, but was too expensive. In 1966 the NZR General Manager Alan Gandell said that the deviation would eliminate five old and narrow tunnels, and that New Zealand topography precluded a fast run , but travel time would be cut from 13½ hours to between 11½ and 12 hours, the best possible without tremendous expense . But two modern express trains were being designed for the NIMT, and should be introduced in three to four years. The central section from Te Rapa near Hamilton to Palmerston North

The section known as the North-South Junction between Wellington and Waikanae , except for 3.3 km (2.1 mi) of single-track through tunnels between North Junction (35.3 km (21.9 mi) from Wellington) and South Junction, (32 km (20 mi) from Wellington), on
2268-682: The NIMT opened in 1873 in Auckland. Construction at the Wellington end began in 1885. The line was completed in 1908 and was fully operational by 1909. It is credited for having been an economic lifeline, and for having opened up the centre of the North Island to European settlement and investment. In the early days, a passenger journey between Wellington and Auckland could take more than 20 hours; today, it takes approximately 11 hours. The NIMT has been described as an "engineering miracle", with numerous engineering feats such as viaducts , tunnels and

The 411 km (255 mi) section between Palmerston North and Hamilton was electrified at 25 kV 50 Hz AC , opened on 24 June 1988 as one of the Muldoon National Government's " Think Big " energy development projects. An overall cost in excess of $ 100 million had been projected, with some 40% being for
2511-603: The NIMT. In 1957 when the installation of CTC over the remaining 354 km (220 mi) commenced, it was estimated that using CTC over the 330 km (205 mi) Taumarunui to Otaki section with control centres at Ohakune (which shifted to Taumarunui in 1977), Taihape and Palmerston North would replace 74 men in traffic working duties. The last section converted was Piriaka-Owhango. A 1926 article by "Backblocks" described conditions for staff at these stations where four workers lived in isolated areas, and their efforts to get special trains for transport to special events. In 1913,

Construction began in 2017, and trains were switched onto the new alignment over the 2019 Easter long weekend (19–22 April). In the Auckland area, a third main line between Wiri and Westfield is under construction; this will allow freight (or other) trains to bypass stationary passenger trains. There are three independent sections of

In prose, the two main islands of New Zealand are called the North Island and the South Island , with the definite article. It is also normal to use the preposition in rather than on , for example "Hamilton
2835-437: The South Island, this is solely due to the North Island having higher natural increase (i.e. births minus deaths) and international migration; since the late 1980s, the internal migration flow has been from the North Island to the South Island. In the year to June 2020, the North Island gained 21,950 people from natural increase and 62,710 people from international migration, while losing 3,570 people from internal migration. At

King Tāwhiao and his followers were able to maintain a rebel Māori monarchy in exile and a refuge for rebel Māori opposed to the government for more than a decade although living conditions were very poor. This may be partly due to

Another Māori name that was given to the North Island, but is now used less commonly, is Aotearoa . Use of Aotearoa to describe the North Island fell out of favour in the early 20th century, and it is now a collective Māori name for New Zealand as

The Royal Commission on Railways created following Aickin's tenure rejected the report's findings. Aickin's successor Horace Lusty , revised the contract with English Electric to specify D class diesel-electric locomotives . They were later found to be unreliable, and only ten were supplied. 42 D class locomotives were supplied instead for secondary lines. For main lines including

3402-650: The diesel fuel price. Part of the project included replacing the copper wire communications system with a new fibre optic communications cable (due to interference caused by AC power with the DC copper wire system) between Wellington and Auckland. In 1994 New Zealand Rail Limited sold the cable to Clear Communications for telephone traffic, leasing part of it back for signalling.

Aickin had previously been Staff Superintendent and Chief Legal Advisor to the Department and considered using diesel locomotives for trains on the NIMT to be too expensive. He turned his attention to electrification, mainly because he saw that it could relieve
3564-529: The edge of the city. Between 1973 and 1981, the major Mangaweka deviation in the central section between Mangaweka and Utiku was built, with three viaducts, all over 70m tall, crossing the Rangitīkei and Kawhatau rivers. The viaducts were at the end of their economic lives. The deviation removed a number of tunnels, many of which were built in unstable country, and eliminated a number of steep gradients. A combined road and rail deviation had bean considered with
3645-523: The eventual route. Four options were considered before the Minister of Public Works decided on the present route in 1884, but, when it was realised just how difficult that route was, further surveys considered two other options in 1888. Routes via Napier and Waitara were also considered, with surveying in Taranaki from 1883 to 1889. Construction of the final central section began on 15 April 1885, when paramount chief Wahanui of Ngāti Maniapoto turned
3726-675: The first sod outside Te Awamutu . It was 23 years before the two lines met, as the central section was difficult to survey and construct. The crossing of the North Island Volcanic Plateau with deep ravines required nine viaducts and the world-famous Raurimu Spiral . Richard Seddon ’s Liberal Government pledged in 1903 that the whole route would be open in 1908. In 1904, the railheads were still 146 km (91 mi) apart, and contracts for three massive viaducts (Makatote, Hapuawhenua and Taonui) were not let until 1905. The government committed 2500 workmen, and in 1907,
3807-431: The fuel consumption further. Electrification's advantages were reflected in the economic evaluation in the report, which showed a rate of return of 18%. Sensitivity analysis showed that this high rate of return gave the project robustness against lower traffic volumes than expected (the return remained positive even if traffic fell), against significant increases in construction cost, and against lower than expected rises in
3888-400: The heavy X class locomotives used on the central mountainous section from 1908. Some 10 bridges between Frankton and Taumarunui had to be strengthened, and in 1914 there was still 129 km (80 mi) of 53 lb/yd rail to be replaced. In the 1930s 85 lb/yd (42.2 kg/m) was adopted, then 91 lb/yd (45.1 kg/m), and from 1974 100 lb/yd (50 kg/m). Signalling on

The North Island had a population of 3,808,005 at the 2023 New Zealand census , an increase of 213,453 people (5.9%) since the 2018 census , and an increase of 570,957 people (17.6%) since the 2013 census . Of the total population, 733,893 people (19.3%) were aged under 15 years, 743,154 (19.5%) were 15 to 29, 1,721,427 (45.2%) were 30 to 64, and 609,534 (16.0%) were 65 or older. Ever since

On 15 May 1872 Te Kooti , on the run from government forces, crossed the Waikato River and entered the territory as supplicant and was granted asylum. In 1880, William Moffat, apparently a land agent or buyer, was shot and killed. In 1881, as a result of ongoing friction with his hosts over

Auckland's first railway was the 13 km (8.1 mi) line between Point Britomart and Onehunga via Penrose, opened in 1873. It was built by Brogdens , as was the rest of the Auckland & Mercer Railway, for £166,000 for the 41 mi (66 km) to Mercer . The section from Penrose to Onehunga is now called the Onehunga Branch .

The double track Tawa Flat deviation opened to goods trains on 22 July 1935 and to passenger trains on 19 June 1937, bypassing the original single track WMR line between Wellington and Tawa . With a pair of tunnels under the Wellington hills, the deviation alleviated issues with more and heavier freight traffic on
4293-699: The line linking the ports of Foxton and Whanganui . In 1882, the Whitaker Ministry passed the North Island Main Trunk Railway Loan Act , to expedite construction of the North Island Main Trunk south of Te Awamutu by authorising the overseas borrowing of a million pounds (probably in London) for the work. From Te Awamutu, it was proposed that the line be built via Taupo or via Taumarunui ,
4374-555: The locomotives, but the final cost was about $ 250 million. The economics of the project was greatly undermined by the fall of the price of oil in the 1980s and the deregulation of land transport, which removed the long-distance monopoly NZR held when the cost-benefit report was written. The electrification of the section, which had its genesis in a study group set up in June 1974 to report on measures to be taken to cope with increasing rail traffic volumes, received approval in 1980. This led to
4455-540: The maximum speed limit on the NIMT was raised to 45 mph (72 km/h), reducing the journey time by 1 hour 25 minutes Auckland-Wellington or to 17 hours and between 30 and 45 minutes. Under Thomas Ronayne , the New Zealand Railways Department general manager from 1895 to 1913, the section south to Parnell was duplicated and improvements made to the worst gradients and tight curves between Auckland and Mercer. Under his successor E. H. Hiley
4536-757: The need to relieve the steep (1 in 57) gradients from Plimmerton to the Pukerua Bay summit by a deviation to the east and allowed more frequent suburban passenger trains (and allowed suburban electric multiple units to run on this section from September 1949). The difficult section down the Paekakariki Escarpment from Pukerua Bay to Paekākāriki with five tunnels between South and North Junctions remains single track. Duplication from Tawa to Porirua opened on 15 December 1957, from Porirua to Paremata on 7 November 1960, and Paremata to Plimmerton on 16 October 1961. The section between Porirua and Plimmerton
4617-500: The north express from Wellington to Ohakune, then transferred to the southbound express, so avoiding the heavy gradients of the central section. The rails and signalling have been upgraded over the years, and many sections of the line have been deviated: The original 1870s Vogel Era track had rails of 40 lb/yd (19.9 kg/m), some were iron not steel; later rails were 53 lb/yd (26.3 kg/m); and from 1901 70 lb/yd (34.8 kg/m), e.g. between Taumarunui and Taihape for

The most common foreign countries of birth were England (15.4% of overseas-born residents), Mainland China (11.3%), India (10.1%), South Africa (5.9%), Australia (5.5%) and Samoa (5.3%). The North Island has a larger population than
4860-497: The power available. Electrification of the NIMT was mooted by electrical engineer Evan Parry in the first volume of the New Zealand Journal of Science and Technology in November 1918. In light of a national coal shortage following World War I , Parry argued that the network was under great strain due to ever-increasing volumes of freight, and the use of steam traction was partly to blame. Parry also noted that there

After successful negotiations between the government, Wahanui , Rewi and Taonui , including a pardon for Te Kooti by 1883 the King Country was made accessible to Europeans. It was opened to road surveying, and the start of the Main Trunk Line - but with a prohibition on

In July 1863, Governor Sir George Grey ordered an invasion of the Waikato with colonial forces supplemented by small numbers of British-allied Maori. The invasion

At a February 1885 meeting at Kihikihi with John Ballance construction of the line was approved. Ballance was criticised for not requiring cession of land alongside the route (which would rise in value because of the line), but he knew that would not be acceptable to Māori. Construction of
5265-486: The sea. While he was not looking, his brothers fought over the fish and chopped it up. This great fish became the North Island, and thus a Māori name for the North Island is Te Ika-a-Māui ("The Fish of Māui"). The mountains and valleys are believed to have been formed as a result of Māui's brothers' hacking at the fish. During Captain James Cook 's voyage between 1769 and 1770 , Tahitian navigator Tupaia accompanied
5346-737: The second Parnell Tunnel with two tracks and an easier gradient was completed in 1915–1916. On the Kakariki bank between Halcombe and Marton a deviation reduced the 1 in 53 grade to 1 in 70 in 1915. Similar work was done to ease the gradient to Greatford, on the other side of the Rangitīkei River, in 1939. A 1914 Act authorised spending on the Westfield Deviation , new stations at Auckland and Wellington, track doubling (Penrose-Papakura, Ohinewai-Huntly, Horotiu-Frankton, Newmarket-New Lynn), and grade easements from Penrose to Te Kuiti, but
5427-676: The single-track sections (most of the line) was controlled by Tyer's Electric Train Tablet No 7 system; with each of the stations for the 94 tablet sections staffed by three tablet porters each working a 56-hour week for continuous coverage; hence each station required at least four houses for the stationmaster and three porters. Pierre noticed that with CTC station buildings and even platforms had been removed as there were no longer any staffed stations between Ohakune and National Park. The Train Control system introduced from 1928 to 1932 supplemented
5508-565: The southern section of the NIMT from Wellington to Paekākāriki was completed. The Tawa Flat deviation has a long tunnel (Tawa No 2) not suitable for steam operation because of excessive smoke (although steam trains were temporarily operated in the new deviation from 1935). A Centralised Train Control (CTC) system was installed in 1940, so that new signal boxes were not required and five stations between Tawa and Pukerua Bay no longer had to be continually staffed for Tablet operation; see Kapiti Line and North–South Junction . Electrification eliminated
5589-587: The steep and twisting original route where long sections at 1 in 60 gradient required banker engines. The Wellington to Johnsonville section of the original line was retained as the Johnsonville Line and the Johnsonville to Tawa section closed. The North-South Junction section from Plimmerton to South Junction, north of Pukerua Bay and Muri, and North Junction to Paekākāriki were duplicated in 1940. From 24 July 1940 electrification at 1500 V DC of
5670-535: The system and Aickin was able to complete a substantial report justifying the NIMT electrification and submit it to the Government. Officers from New Zealand Treasury and the Ministry of Works and two experts from Sweden (Thelander and Edenius) commented on the proposal and in December 1950 the Government granted approval in principle and agreed to appoint Thelander as a consultant. Aickin later fell out with
5751-402: The tablet system by operators at the four sections (Auckland, Frankton, Te Kuiti, Ohakune, Marton and Wellington) to expedite operation of trains over several tablet sections; the 1925 Fay-Raven report urged its adoption because of the fitful progress of mixed trains, with locomotives often kept waiting. From 1938 to 1966 Centralised Traffic Control (CTC) gradually replaced the tablet system on
5832-462: The then National Government and retired as General Manager in July 1951. With the change in regime, the electrification proposal disappeared. A key assumption of Aickin's report was that traffic on the NIMT would grow by 50% from 1948 to 1961. Since a diesel-electric locomotive is a travelling power station, the savings through electrification compared to diesel could be regarded as the difference between
5913-593: The town of Ōtorohanga in the north to the upper reaches of the Whanganui River in the south, and from the Hauhungaroa and Rangitoto Ranges in the east to near the Tasman Sea in the west. It comprises hill country, large parts of which are forested. The region, albeit loosely defined, is very significant in New Zealand's history. The term "King Country" dates from the New Zealand Wars of
5994-466: Was electrified between 1984 and 1988 as part of the Think Big government energy program. Some tunnels were opened out or bypassed by deviations while in others clearances were increased, and curves eased. The section between Ohakune and Horopito was realigned with three viaducts replaced to handle higher loads and speeds. The most notable bridge replaced was the curved metal viaduct at Hapuawhenua by
6075-541: Was aimed at suppressing Kingite power, which was seen by the colonial government as a threat to Crown authority in New Zealand; it was also aimed to drive Waikato Maori from the region in readiness for occupation and settlement by Pakeha settlers . Heavily outnumbered and disadvantaged by superior firepower, the Kingite forces retreated southwards from the Waikato after the battle at Ōrākau in April 1864, eventually being forced to flee to Maniapoto land, later called
6156-598: Was closed on 7 August 1908 for the first through passenger train, the 11-car Parliamentary Special carrying the Prime Minister Sir Joseph Ward and other parliamentarians north to see the American Great White Fleet at Auckland. But much of the new section was temporary, with some cuttings north of Taonui having vertical batters and unballasted track from Horopito to Makatote. Ward drove the last spike on 6 November 1908, and
6237-602: Was completed as part of the upgrade and expansion of the Wellington suburban network; see Kapiti Line for more information. In 2012–13, four bridges near Rangiriri between Auckland and Hamilton were replaced. The bridges were all over 100 years old with steel spans and timber piers, and were replaced by modern low-maintenance concrete ballast deck bridges. Bridges 479, 480, 481 & 482 were replaced, with lengths of 40 metres (131 ft 3 in), 40 metres (131 ft 3 in), 30 metres (98 ft 5 in) and 18 metres (59 ft 1 in) respectively. The construction of
6318-470: Was doubled from 11 November 1951, Pukekohe to Pokeno 21 November 1954, Mercer to Amokura 1 July 1956 and Ohinewai to Te Kauwhata 14 December 1958. The 13 km (8.1 mi) between Amokura and Te Kauwhata remain single track, as does Ngāruawāhia bridge. Doubling of the section south of Amokura is being investigated in a business case from July 2021. In 1930, the Westfield deviation was opened, creating
6399-564: Was great potential for cheap hydro-electricity generation in the central North Island to power electrification. The first part of the NIMT to be electrified was the Wellington – Paekakariki section via the Tawa Flat deviation that was completed on 24 July 1940. This was largely to prevent smoke nuisance in the 4.3 km No. 2 tunnel, and to provide for banking on the Paekakariki to Pukerua Bay section. Electric traction in this section
6480-462: Was later continued south from Penrose into the Waikato. To support the Invasion of the Waikato , a 3.5 mi (5.6 km) tramway was built from Maungatāwhiri to Meremere in 1864, with a first sod event near Koheroa on Tuesday, 29 March 1864 by Auckland's Chief Superintendent of Roads & Bridges, W R Collett . Turning of the first sod of the Auckland and Drury Railway took place in 1865,
6561-460: Was straightened in conjunction with the duplication by reclaiming land along the eastern shore of Porirua Harbour. In 1967, the floors of the tunnels on the former WMR section between Paekākāriki and Pukerua Bay were lowered to enable the D class locomotives to travel all the way to Wellington. Between 1964 and 1966, a deviation away from the centre of Palmerston North via the Milson deviation on
