New Zealand is a country in the southern Pacific Ocean comprising two large islands (the North Island and the South Island) and numerous smaller islands, most notably Stewart Island and the Chatham Islands. The Realm of New Zealand also includes the Cook Islands and Niue, which are self-governing, but in 'free association'; Tokelau; and the Ross Dependency (New Zealand's Antarctic territorial claim). New Zealand is notable for its geographic isolation, being separated from Australia to the northwest by the Tasman Sea, approximately 2000 kilometers (1250 miles) across. Its closest neighbours to the north are New Caledonia, Fiji, and Tonga.
The population is mostly of European descent, with the native Māori being the largest minority. Non-Māori Polynesian and Asian people are also significant minorities, especially in urban areas. Elizabeth II, as the Queen of New Zealand, is the Head of State and is represented, in her absence, by a non-partisan Governor-General; the Queen 'reigns but does not rule', so she has no real political influence. Political power is held by the democratically-elected Parliament of New Zealand under the leadership of the Prime Minister who is the Head of Government.
