New Zealand's history: one treaty in two languages

Who settled the islands before Europeans came

No human remains, artefacts or structures in New Zealand have been confidently dated to before the Kaharoa Tephra, the ash layer laid down by the eruption of Mount Tarawera around 1314 CE. Rat bones, pollen and the genetic variability of Māori populations point the same way, and the main period of Polynesian settlement is now placed in the decades after that eruption, possibly as a coordinated migration. Traditional genealogies (whakapapa) put the arrival of many founding canoes (waka) at around 1350. An older reading of the oral record, which had the explorer Kupe arriving around 750 CE and a single great fleet around 1350, has been set aside by prehistorians since the late twentieth century.

The settlers found islands with no native land mammals apart from some bats. They hunted moa, large flightless birds, to extinction by about 1500, cleared about 40% of the original forest with fire, and grew the kūmara, taro, gourds and yams they had brought from eastern Polynesia. Where the climate allowed, horticulture became the base of life; in the far south, where it did not, fernroot and cultivated cabbage trees took its place. Some settlers crossed to the Chatham Islands, probably in the fifteenth century, and their culture developed there as Moriori.

Society was organised by kinship. The whānau, the extended family, sat inside the hapū, and related hapū made up the iwi. Chiefs, male or female, held authority that was often inherited but had to be kept by ability. Fortified villages (pā) multiplied as competition for land grew, and history was held in oratory, song and genealogies that specialists could recite for hundreds of years.

How traders and missionaries changed early contact

The first Europeans known to reach the islands were the crew of Abel Tasman, who anchored in Golden Bay in December 1642 and left after a clash with Ngāti Tūmatakōkiri. Dutch cartographers named the land Nova Zeelandia in 1645. James Cook arrived in HM Bark Endeavour in October 1769, mapped the coast and came back on both of his later voyages. From the 1790s British, French and American whaling, sealing and trading ships worked these waters, and their crews traded guns and metal tools for food, timber and flax.

Samuel Marsden brought Christianity to the Bay of Islands in 1814, and the Church Missionary Society had more than 20 stations by 1840. From 1820 the linguist Samuel Lee worked with the chief Hongi Hika to write the language down, and the first successful printing in the country, in 1835, was two books of the Bible in Māori. By 1845, 64,000 Māori were attending church services, more than half of an estimated population of 110,000.

The musket changed war. Between 1805 and 1843 tribes that had guns attacked tribes that did not, until most had them and a new balance settled. In 1835 the Moriori of the Chatham Islands were attacked and enslaved by Ngāti Mutunga and Ngāti Tama from the mainland. That same year James Busby, appointed British Resident in 1832 with no power to make or enforce law, had northern chiefs sign He Whakaputanga, the Declaration of Independence, which placed sovereign authority in a Confederation of United Tribes. Britain recognised it.

What the two texts of the Treaty promise

The New Zealand Company's plan of 1839 to buy large tracts and send settlers pushed the Colonial Office to act. William Hobson arrived as lieutenant-governor at the end of January 1840. The Treaty was drafted in a few days, and the missionary Henry Williams and his son Edward translated it into Māori overnight on 4 February. About 500 Māori debated it for a day and a night, and about 40 chiefs, starting with Hōne Heke, signed on 6 February. By September some 500 more had signed copies carried around the country, almost all of them the Māori text. Several chiefs refused or were never asked, among them Pōtatau Te Wherowhero of Waikato. Hobson proclaimed British sovereignty over the whole country on 21 May 1840, the North Island by treaty and the South Island and Stewart Island by discovery.

Sovereignty had no direct equivalent in Māori, and the translators used kawanatanga, a transliteration of "governance" then in use. The Ministry for Culture and Heritage records the two readings this produced. One holds that the Treaty was drafted in haste by amateurs whose Māori conveyed a different meaning from the English. The other holds that Hobson's instructions were careful and that the translators knew the language and the chiefs well. The same account notes that at the time the oral discussion and Williams's explanation may have mattered more than the written texts. Legally there is one Treaty, and since 1975 the power to decide what its two texts mean has rested with the Waitangi Tribunal.

Why war followed the land sales

Settlers arrived faster than Māori had expected. The Pākehā population grew from fewer than 1,000 in 1831 to 500,000 by 1881, and under the Treaty's second article only the Crown could buy land from Māori. Until about 1860 Auckland bought most of its food from Māori growers, and several iwi owned mills and ships. Conflict came where the question was whose authority ran in a given district.

Te Ara, the Encyclopedia of New Zealand, dates the first fighting to the 1840s: the Wairau clash with Ngāti Toa in 1843, then the Northern War, which began at Kororāreka on 11 March 1845 and ended in January 1846 with no Ngāpuhi land confiscated. The longer war began in Taranaki in 1860 over a disputed purchase at Waitara. Waikato and central North Island iwi had proclaimed a king of their own in 1858, Pōtatau Te Wherowhero, one of the chiefs who had refused to sign in 1840, and the movement behind him, the Kīngitanga, held the Waikato. On 12 July 1863 British troops crossed the Mangatāwhiri Stream into its territory. At the height of the 1860s campaigns about 18,000 British troops faced about 4,000 Māori fighters. The last campaigns, fought largely by colonial troops and Māori allies against followers of prophetic leaders, ran to 1872.

No accurate casualty count exists. The historian James Cowan put the dead of the British and colonial forces at over 500, their Māori allies (kūpapa) at about 250, and those who fought the Crown at about 2,000, in a Māori population of about 60,000. The New Zealand Settlements Act 1863 allowed land to be taken from those deemed in rebellion. Te Ara gives the confiscated area as about 1 million hectares, including land later returned; the Wikipedia account of the wars gives 1.5 million hectares and says loyal and rebel tribes lost land alike.

The confiscations were resisted after the fighting stopped. At Parihaka in Taranaki the prophets Te Whiti-o-Rongomai and Tohu Kākahi led peaceful protest until government forces occupied the settlement on 5 November 1881. The Māori population, estimated at about 86,000 in 1769, had fallen to about 42,000 by 1896.

How the colony governed itself and voted

The British Parliament's New Zealand Constitution Act 1852 created an elected General Assembly, which first met on 24 May 1854, and six provincial governments, abolished with effect from 1877. Four Māori electorates were added to the House of Representatives in 1867. Gold found at Gabriel's Gully in Otago in 1861 more than doubled the population, from 71,000 in 1859 to 164,000 in 1863. From 1870 Julius Vogel borrowed in London to build railways and assist immigration, and public debt rose from £7.8 million in 1870 to £18.6 million in 1876. Refrigerated shipping from 1882 let frozen meat and dairy reach Britain, and it carried the economy until the 1970s.

The Liberal government that took office in 1891 bought 3.1 million acres of Māori land and 1.3 million acres of large estates between 1891 and 1911 to settle small farmers, and introduced old-age pensions and a system of arbitration for industrial disputes. Women's suffrage passed the Legislative Council on 8 September 1893 by 20 votes to 18, after the House had passed bills in 1891 and 1892 that the council blocked. Lord Glasgow signed it on 19 September, giving the vote to women aged 21 and over who were British subjects, Māori women among them. Women gained the right to stand for Parliament in 1919, and Elizabeth McCombs became the first woman elected, in 1933.

New Zealand stayed out of the Commonwealth of Australia created on 1 January 1901. It became the Dominion of New Zealand on 26 September 1907, and Britannica dates full independence to its adoption of the Statute of Westminster in 1947.

What two world wars and Britain's turn changed

About 100,000 New Zealanders served overseas in the First World War; 18,000 died, more than 2,700 of them at Gallipoli. The Labour Party was formed in 1916. Taranaki and Waikato Māori, whose land had been confiscated, were reluctant to enlist. In 1935 the first Labour government began building a welfare state with state housing, free health care and education, kept and extended by every government until the 1980s. The Second World War took about 120,000 troops from a population of 1.7 million.

After 1945 the country was a founding member of the United Nations, and in 1951 it signed the ANZUS treaty with Australia and the United States. Its economy still faced Britain: in 1961 slightly over 51% of exports went to the United Kingdom. In 1973 Britain joined the European Economic Community and ended its preferential trade agreements, and New Zealand had to find other markets. The 1973 oil crisis followed in the same year.

How the state came to reopen the Treaty

Māori moved to the cities after the Second World War: about 20% lived in urban areas before it and 80% by the 1980s. A protest movement formed in the late 1960s, calling on the government to honour the Treaty, and in 1968 Māori boycotted Waitangi Day over a law seen as another land grab. Parliament answered with the Treaty of Waitangi Act 1975, which set up the Waitangi Tribunal as a permanent commission of inquiry, at first limited to breaches after 1975. An amendment in 1985 let it investigate Crown actions back to 1840.

The tribunal finds facts and recommends; settlement is negotiated with the Crown. More than 2,000 claims had been lodged by the time the Ministry for Culture and Heritage wrote its summary of the Treaty. The government began negotiating settlements of historical claims in the early 1990s, and Te Ara dates the start of reparations for the 1863 confiscations to the settlement between the Crown and Waikato-Tainui in 1995. The Treaty is still not part of domestic law except where an Act names its principles, and by 2021 more than 35 principal Acts did. What those principles are is argued over in Parliament: a bill to delete references to them was introduced in 2005 and failed at its second reading in November 2007, a referendum on redefining them has been proposed, and an RNZ-Reid Research poll in 2026 found 38% saying the Treaty had too much influence on government and 34% saying it had about the right amount.

Why the voting system and the economy were rebuilt

The Fourth Labour Government, elected in 1984 amid an economic and constitutional crisis, floated the dollar, ended farm subsidies, sold state assets and cut the top tax rate from 65% to 33%. It also passed the Constitution Act 1986, which ended the force of the British Parliament's Act of 1852. Its foreign policy made the country nuclear-free and, in effect, took it out of the ANZUS alliance, and the sinking of the Rainbow Warrior by the French intelligence service did much to make the anti-nuclear stance a symbol of national identity.

Voters who saw governments ignore the mood of the electorate chose a new voting system in referendums in 1992 and 1993, and the first election under mixed-member proportional representation was held in 1996. The Supreme Court Act 2003 replaced appeals to the Privy Council in London with a Supreme Court of New Zealand, which began sitting in 2004. On 15 March 2019 a gunman killed 51 people at two Christchurch mosques, and semi-automatic centrefire rifles were banned in response. In March 2020 the borders closed to non-residents and a national lockdown began late in the month to stop the spread of COVID-19.
