New Zealand is the most geographically isolated of all countries. Its closest neighbour Australia is 2,000 km to the northwest of the main islands across the Tasman Sea. The only landmass to the south is Antarctica, and to the north are New Caledonia, Fiji, and Tonga.
Since 1876, local government has administered the various regions of New Zealand. Due to its colonial heritage, New Zealand local government was modelled fairly closely on British local government structures, with elected city, borough, and county councils. Over the years some of these councils merged or had boundary adjustments by mutual agreement, and a few new ones were created. In 1989, the government completely reorganised local government, implementing the current two-tier structure of regional councils and territorial authorities.
The first Europeans known to reach New Zealand were the crew of Dutch explorer Abel Tasman's ships Heemskerck and Zeehaen, which anchored at the northern end of the South Island in December 1642 but sailed northward to Tonga following a clash with local Maori. Tasman sketched sections of the two main islands' west coasts. Tasman called them "Nova Zeelanda." The name Nieuw Zeeland appeared on charts of the area shortly afterward, having earlier been applied to an island near New Guinea. Lieutenant James Cook of His Majesty's Barque Endeavour made a fuller reconnaissance, surveying the shores of both islands in 1769 - 1770. Cook returned to New Zealand in both his subsequent Pacific voyages.
Confronted like Australia with the strategic implications of Britain's 20th-century eclipse as a world power of the first rank, New Zealand joined with Australia and the United States in the ANZUS pact in 1951, but the US suspended its defence commitments to the country in 1986 after the then Labour government banned nuclear-powered or armed ships from New Zealand ports.
New Zealand (like Fiji) decided against joining the Commonwealth of Australia in 1901, and instead changed from being a colony to a separate "dominion" in 1907, equal in status to Australia and Canada. New Zealand retained an avowed loyalty to the British Empire of which it formed a part, and contributed proportionally large numbers of troops to aid Britain in the Boer War (1899 - 1902), World War I and World War II (see New Zealand in World War II). New Zealand's complete independence was formalised by the 1926 Balfour Declaration and the 1931 Statute of Westminster, ratified on November 25, 1947. The monarch of the United Kingdom remains the monarch of New Zealand, which has been an independent constitutional monarchy. In 1951, the Legislative Council was abolished as ineffectual, thereby creating a unicameral legislature.
For a variety of reasons many Maori and Pacific people have been socially disadvantaged, forming an underclass in some areas. Cultural considerations for both Maori and Pacific people now have a significant influence on educational, medical and social organisations, particularly in areas with high concentrations of these population groups.
Self-government was granted to the settler population in 1852, under the UK Parliament's New Zealand Constitution Act 1852, with a General Assembly consisting of an appointed Legislative Council and an elected House of Representatives. In 1867, Maori won the right to a certain number of reserved seats in parliament. During this period, the livestock industry began to expand, and the foundations of New Zealand's modern economy took shape. By the end of the 19th century, improved transportation facilities made possible a great overseas trade in wool, meat, and dairy products.
New Zealand was featured as the setting for "Middle Earth" in the renowned early 21st century trilogy of films based on Tolkien's Lord of the Rings books. It has brought an additional interest in tourism to the nation.
Of New Zealand's four million people, roughly three million live in the North Island and one million in the South Island. These islands are among the largest in the world and the combined land area is comparable to the British Isles or the US state of Colorado. Along with Aotearoa, another Maori name for New Zealand was Niu Tireni, a transliteration of the English name.
