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.
