New Zealand is an island country in the southwestern Pacific Ocean. The country geographically comprises two main landmasses ‒ that of the North and South Islands ‒ and numerous smaller islands. New Zealand is situated some 1,500 kilometres (900 mi) east of Australia across the Tasman Sea and roughly 1,000 kilometres (600 mi) south of the Pacific island nations of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans.
Polynesians settled New Zealand in 1250–1300 CE and developed a distinctive Māori culture, and Europeans first made contact in 1642 CE. The introduction of potatoes and muskets triggered upheaval among Māori early during the 19th century, which led to the inter-tribal Musket Wars. In 1840 the British and Māori signed a treaty making New Zealand a colony of the British Empire. Immigrant numbers increased sharply and conflicts escalated into the New Zealand Wars, which resulted in much Māori land being confiscated in the mid North Island. Economic depressions were followed by periods of political reform, with women gaining the vote during the 1890s, and a welfare state being established from the 1930s. After World War II, New Zealand joined Australia and the United States in the ANZUS security treaty, although the United States later suspended the treaty. New Zealanders enjoyed one of the highest standards of living in the world in the 1950s, but the 1970s saw a deep recession, worsened by oil shocks and the United Kingdom's entry into the European Economic Community. The country underwent major economic changes during the 1980s, which transformed it from a protectionist to a liberalised free trade economy; once-dominant exports of wool have been overtaken by dairy products, meat, and recently wine.
