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.
The conservative National Party and the left-leaning Labour Party have dominated New Zealand political life since a Labour government came to power in 1935. During 14 years in office (1935 - 1949), the Labour Party implemented a broad array of social and economic legislation, including comprehensive social security, a large scale public works programme, a 40-hour working week, a minimum basic wage, and compulsory unionism. The National Party won control of the government in 1949 and adopted many welfare measures instituted by the Labour Party. Except for two brief periods of Labour governments in 1957 - 1960 and 1972 - 1975, National held power until 1984.
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.
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.
In October 1990, the National Party again formed the government, for the first of three, three-year terms. In 1996 New Zealand elected its first MMP Parliament. The system was designed to increase representation of smaller parties in Parliament and appears to have done so. Since 1996, neither the National nor the Labour Party has had an absolute majority in Parliament, and for all but one of those years, the government has been a minority one. The current Labour government followed its November 1999 election success by outpolling National 41 per cent to 21 per cent in the July 2002 general election. Labour formed a coalition, minority government with Jim Anderton's Progressive Coalition, a left-wing party (subsequently named "Progressive Party") which holds two seats in Parliament.
Because of its long isolation from the rest of the world, New Zealand has extraordinary flora and fauna. Until the arrival of the first humans just a millennium or two ago, 80% of the land was forested and, barring two species of bat, there were no non-marine mammals at all. Instead, New Zealand's forests were inhabited by a diverse range of birds (many of them flightless), reptiles, and insects—some of them almost the size of a mouse (see weta).
While New Zealand, like Australia, prides itself as being more egalitarian than Britain, there is a degree of inverse snobbery known as the 'Tall Poppy Syndrome', in which people who are seen as (over)ambitious and having ideas above their station are cut down to size. This is also known as the 'Great Kiwi Clobbering Machine', and has prompted many of the country's best and brightest to emigrate.
The usual climate throughout the country is mild, mostly cool temperate to warm temperate, with temperatures rarely falling below 0°C or rising above 30°C. Conditions vary from wet and cold in Southland and the West Coast of the South Island, where most of the country's rain falls, to subtropical in Northland. In Wellington the average minimum temperature in winter is 5.9°C and the average maximum temperature in summer is 20.3°C.
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.
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 has a strong party system in place. The first political party was founded in 1891, and its main rival was founded in 1909 — from that point until a change of electoral system in 1996, New Zealand had a two-party system in place. Today, New Zealand has a genuinely multi-party system, with eight parties currently represented in Parliament. Neither of the two largest parties has been able to govern without support from other groups since 1996, meaning that coalition government is common.
From the 1790s the waters around New Zealand were visited by British, French, and American whaling ships, whose crews sometimes came into conflict with Maori inhabitants. The arrival of traders and missionaries in the 1800s and 1810s added to local disputes. The first full-blooded European infant in the territory, Thomas King, was born in 1815 in the Bay of Islands. The initiation of a programme of large-scale settlement and land purchases in 1839 by the New Zealand Company, coupled with increasing French interest in the islands, finally prompted the British government to take control of the situation.
In 2004 it began discussing free trade with China, one of the first countries to do so.
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).
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.
