New Zealand, Māori Aotearoa, island country in the South Pacific Ocean, the southwesternmost part of Polynesia. New Zealand is a remote land—one of the last sizable territories suitable for habitation to be populated and settled—and lies more than 1,000 miles (1,600 km) southeast of Australia, its nearest neighbour. The country comprises two main islands—the North and the South Island—and a number of small islands, some of them hundreds of miles from the main group. The capital city is Wellington and the largest urban area Auckland; both are located on the North Island. New Zealand administers the South Pacific island group of Tokelau and claims a section of the Antarctic continent. Niue and the Cook Islands are self-governing states in free association with New Zealand. New Zealand is a land of great contrasts and diversity. Active volcanoes, spectacular caves, deep glacier lakes, verdant valleys, dazzling fjords, long sandy beaches, and the spectacular snowcapped peaks of the Southern Alps/Kā Tiritiri o te Moana on the South Island—all contribute to New Zealand’s scenic beauty. New Zealand also has a unique array of vegetation and animal life, much of which developed during the country’s prolonged isolation. It is the sole home, for example, of the long-beaked, flightless kiwi, the ubiquitous nickname for New Zealanders. New Zealand was the largest country in Polynesia when it was annexed by Great Britain in 1840. Thereafter it was successively a crown colony, a self-governing colony (1856), and a dominion (1907). By the 1920s it controlled almost all of its internal and external policies, although it did not become fully independent until 1947, when it adopted the Statute of Westminster. It is a member of the Commonwealth.
