The Cabinet, which is responsible to Parliament, exercises executive authority. (The Cabinet forms the practical expression of a formal body known as the Executive Council.) The Prime Minister, as the leader of the political party or coalition of parties holding the majority of seats in the House of Representatives, leads the Cabinet. All Cabinet Ministers must be Members of Parliament (MPs) and are collectively responsible to it.
Christianity is the predominant religion in New Zealand, although over a quarter of the population has no religious affiliation. The main Christian denominations are Anglicanism, Presbyterianism, Roman Catholicism and Methodism. There are also significant numbers who identify themselves with Pentecostal and Baptist churches and with the Mormon church. The New Zealand-based Ratana church has many adherents among Maori. According to census figures, other significant minority religions include Hinduism, Buddhism and Islam.
After the Second World War, significant immigration from the Pacific Islands began, so much so that there are now more nationals from some Pacific island nations living in New Zealand than on their home islands. The wide variety of Pacific Island cultures has combined in New Zealand, mostly in South Auckland, to form a distinctive subculture that is separate from the Maori culture.
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).
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.
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.
Maori population figures plummetted after 1820 due to tribal wars (the musket wars) and to unfamiliar diseases - measles, whooping cough, influenza and later typhoid - reducing an initial Maori population of perhaps 100,000 to 120,000 (lower than many contemporary figures, which probably overestimated densities in the South Island) to only 62,000 by 1857 and 44,000 in 1891. Recovery began slowly (though three decades earlier than among Australia's still worse-affected Aborigines), with numbers reviving steadily after the setback of the 1918 influenza pandemic. By 1900 also, Maori had lost most of their land, usually as a result of sales or of confiscations after armed conflict with the settler government.
Although less obvious today, in the past team sports, particularly Rugby football, gambling on horse races, and sharing a beer after a hard day's work with some good friends or work mates have been significant images of New Zealand life. This predominantly working-class male cultural image has previously been so strong that it has overshadowed other, perhaps higher, cultural aspects of New Zealand society.
During the late 1980s, the New Zealand Government sold a number of major trading enterprises, including its telecommunications company, railway network, a number of radio stations and two financial institutions in a series of asset sales. Although the New Zealand Government continues to own a number of significant businesses, collectively known as State-Owned Enterprises (SOEs), they are operated through arms-length shareholding arrangements as stand alone businesses that are required to operate profitably, just like any privately owned enterprise. Various items of protective legislation establish business objectives yet prevent shareholding governments from having influence over day to day operations of the business.
Kiwi (usually capitalised) has been applied to and adopted by New Zealanders as a nickname for themselves and as an adjective for their culture. It originates from kiwi (usually uncapitalised), the Maori word for several species of flightless birds endemic to New Zealand. The plural form for New Zealanders is always Kiwis. The plural forms for the birds are the anglicised kiwis or, following the Maori language, kiwi without an s.
New Zealand has no native land mammals apart from some rare bats. Later Maori largely subsisted by cultivating the kumara, a type of sweet potato, which they had brought with them from Polynesia.
Immigration policy in New Zealand has often been controversial, with some politicians claiming that the pace of immigration has been too rapid for New Zealand to absorb, and that recent immigrants are having trouble adapting to the New Zealand society. This position is seen by others as a cynical appeal to xenophobic sentiment in order to gain votes near election time, and these views are not widely supported by the general population.
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.
New Zealand's scenery has appeared in a number of television programmes and films. In particular, Hercules and Xena were filmed around Auckland, Heavenly Creatures in Christchurch. The Tribe is set and filmed here too. Peter Jackson shot the epic The Lord of the Rings trilogy in various locations around the country, taking advantage of the spectacular and relatively unspoiled landscapes, and Mount Taranaki was used as a stand-in for Mount Fuji in The Last Samurai. Other movies currently filming in New Zealand include King Kong and The Lion, the Witch and the Wardrobe.
