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.
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.
New Zealand has no formal, written constitution; the constitutional framework consists of a mixture of various documents (including certain acts of the United Kingdom and New Zealand Parliaments) and constitutional conventions. Most constitutional provisions became consolidated into the Constitution Act 1986. There have, at times, been proposals for a formal constitution, but there have not yet been any serious moves to adopt one.
New Zealand does possess the usual cultural activities such as theatre, dance, fine arts, classical and popular music and creative writing. However, due to the small population base and a lack of arts funding sources, many artists have struggled to sustain themselves economically, even though they may achieve popular success. For this reason many of New Zealand's best artists go overseas, especially to Australia, but also to Europe or America, so they can further their careers.
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 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.
New Zealand has a modern, developed economy. Its primary export industries are agriculture, horticulture, fishing, forestry and information technology. There are also substantial tourism and export education industries. The film and wine industries are considered to be up-and-coming.
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.
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.
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.
New Zealand functions as a constitutional monarchy with a parliamentary system of government. The basic system is closely patterned on that of the United Kingdom, although a number of significant modifications have been made. The head of state is Queen Elizabeth II, but actual government is conducted by a Prime Minister and Cabinet drawn from an elected Parliament.
In 2004 it began discussing free trade with China, one of the first countries to do so.
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.
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).
Because many New Zealanders have to go elsewhere in the world to achieve fame and fortune, New Zealand society is keen to attribute famous people as being New Zealanders, however short their residency in New Zealand might have been. While being born in New Zealand is an absolute qualification for being identified as a New Zealander, attendance at a New Zealand school, or being a permanent resident in New Zealand when fame is initially achieved also qualifies, irrespective of national origin. This sometimes leads to famous people being identified as coming from both New Zealand and another country - often Australia, such as the pop group Crowded House, the actor Russell Crowe, and the Pavlova dessert, all of which are claimed by Aussies and Kiwis as 'theirs'. However, New Zealanders are generally proud to have disowned controversial figures such as Sir Joh Bjelke-Petersen.
