High Quality Content by WIKIPEDIA articles! The demographics of New Zealand encompass the gender, ethnic, religious, geographic, and economic backgrounds of the 4.4 million people living in New Zealand. New Zealanders, informally known as "Kiwis", predominantly live in urban areas within the North Island. The four largest cities are Auckland (with one-third of the country`s population), Christchurch, Wellington and Hamilton. Few New Zealanders live outside the main North and South Islands. Waiheke Island (near Auckland) is easily the most populated smaller island with 7,689 residents, while Great Barrier Island, the Chatham and Pitt Islands and Stewart Island each have populations below 1,000. New Zealand is part of a realm and the most people born in the realm`s external territories of Tokelau, the Ross Dependency, the Cook Islands and Niue are considered New Zealanders. In 2006, more people who identified themselves with these islands lived in New Zealand than on the Islands themselves.
