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.
Today New Zealand has 12 regional councils for the administration of environmental and transport matters and 74 territorial authorities that administer roading, sewerage, building consents, and other local matters. The territorial authorities are 16 city councils, 57 district councils, and the Chatham Islands Council. Four of the territorial councils (one city and three districts) and the Chatham Islands Council also perform the functions of a regional council and thus are known as unitary authorities. Territorial authority districts are not subdivisions, as such, of regional council districts and a few of them straddle regional council boundaries.
New Zealand comprises two main islands and a number of smaller islands. The South Island is the largest land mass, and is divided along its length by the Southern Alps, the highest peak of which is Mount Cook, at 3754 metres. There are 18 peaks of more than 3000 metres in the South Island. The North Island is less mountainous than the South, but is marked by volcanism. The tallest North Island mountain, Mount Ruapehu (2797 metres), is an active cone volcano.
Partly because of its geographical isolation from neighbouring countries, and partly because of the number and location of numerous uninhabited islands belonging to it, New Zealand's Exclusive economic zone of marine resources was the world's fifth largest, at 4.2 million square kilometres in the year 2000 (according to New Zealand's National Institute of Water and Atmospheric Research).
New Zealand's most popular sports are rugby (primarily rugby union but also rugby league), soccer (the most popular sport amongst children), cricket, and netball (the sport with the most players); golf, tennis, rowing and a variety of water sports, particularly sailing. Snow sports such as skiing and snowboarding are also popular. Equestrian sportsmen and sportswomen make their mark in the world (Mark Todd being chosen international "Horseman of the Century"), and all the way down to the juniors at pony club level.
Political separation of the two islands was an issue in the 1860s. The more populous North Island was riven by war and political turmoil while the South Island was prospering, especially after gold was discovered (1861) at Gabriel's_Gully in Central Otago. The South Island grew very tired of financially supporting the North Island while receiving very little in return. The feeling was particularly bitter between Auckland and Otago where Dunedin journalist, Julius Vogel began a strong campaign to make the South Island completely independent. The matter was put to a vote in Parliament on September 19, 1865. Seventeen members voted for separation and 31 for unity, so New Zealand remained united. Vogel later became Prime Minister of a united New Zealand.
New Zealand is a unitary state rather than a federation — regions are created by the authority of the central government, rather than the central government being created by the authority of the regions. Local government in New Zealand has only the powers conferred upon it by Parliament. These powers have traditionally been distinctly fewer than in some other countries. For example, police and education are run by central government, while the provision of low-cost housing is optional for local councils. Many of them used to control ports and gas and electricity supply, but nearly all of that was privatised in the late 20th century.
Britain was motivated by the desire to forestall other European powers (France established a very small settlement on Banks Peninsula in the South Island at Akaroa also in 1840) and to end the lawlessness of European (predominantly British) whalers and traders. Maori chiefs were motivated by the promises of protection of their existing possessions (which was only partially carried out) and by the promise of protection against other Maori using muskets obtained from European whalers and traders (the Musket Wars of 1820-1835).
