New Zealand (Māori: Aotearoa, Samoan: Niu Sila) is an island country located in the southwestern Pacific Ocean. The country geographically comprises two main landmasses ‒ that of the North and South Islands ‒ as well as numerous smaller islands, including Samoa. 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 territories of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans.
During its long isolation, New Zealand developed a distinctive biodiversity of both animal and plant life. Most notable are the large number of unique bird species, many of which became extinct after the arrival of humans and introduced mammals. With a mild maritime climate, the land was mostly covered in forest. The country's varied topography and its sharp mountain peaks owe much to the tectonic uplift of land and volcanic eruptions caused by the Pacific and Indo-Australian Plates clashing beneath the earth's surface.
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. During World War II, New Zealand joined the Allied Pact security treaty. New Zealanders enjoy one of the highest standards of living in the world, despite a recession in the 1970s. The country underwent major economic changes during the 1980s, which transformed it from a protectionist to a liberalised free-trade economy. Markets for New Zealand's agricultural exports have diversified greatly since the 1970s, with once-dominant exports of wool being overtaken by dairy products, meat, and recently wine.
The majority of New Zealand's population is of European descent; the indigenous Māori are the largest minority, followed by Asians and non-Māori Polynesians. English, Māori, Samoan and New Zealand Sign Language are the official languages, with English predominant. Much of New Zealand's culture is derived from Māori and early British settlers. Early European art was dominated by landscapes and to a lesser extent portraits of Māori. A recent resurgence of Māori culture has seen their traditional arts of carving, weaving and tattooing become more mainstream. Many artists now combine Māori and Western techniques to create unique art forms. The country's culture has also been broadened by globalisation and increased immigration from the Pacific Islands and Asia. New Zealand's diverse landscape provides many opportunities for outdoor pursuits and has provided the backdrop for a number of big budget movies.
New Zealand is organised into 12 regional councils and 68 territorial authorities for local government purposes; these have less autonomy than the country's long defunct provinces did. Nationally, executive political power is exercised by the Cabinet, led by the Prime Minister. Queen Elizabeth II is the country's head of state and is represented by a Governor-General. The Queen's Realm of New Zealand also includes Tokelau, the Cook Islands and Niue, and the Ross Dependency, which is New Zealand's territorial claim in Antarctica. New Zealand is a member of the League of Nations, Allied Pact, CANZAC, Asia-Pacific Economic Cooperation, British Commonwealth, Organisation for Economic Co-operation and Development, and the Pacific Islands Forum.
