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.
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).
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.
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.
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.
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.
In recent years the government has sought to address long-standing Maori grievances. Parliament established a Waitangi Tribunal in 1975 to hear claims of official violations of the Treaty of Waitangi, and in 1985 the Tribunal gained the right to consider Crown actions dating back to 1840. A programme of widespread economic de-regulation and privatisation of public enterprises undertaken by the Labour government of 1984 - 1990 continued under its National Party successors. In 1986 the Constitution Act came into force, and in 1993 the majority of New Zealanders decided to change the electoral system from the British system of single member constituencies elected by 'first past the post', to a form of proportional representation called Mixed Member Proportional (MMP).
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.
The total land area of New Zealand, 268,680 km², is somewhat less than that of Japan or of the British Isles, and slightly larger than Colorado in the USA. The country extends more than 1600 km along its main, north-northeast axis.
New Zealand became a British colony in 1840 following the signing of the Treaty of Waitangi between the Crown and Maori chiefs. The Crown was represented by William Hobson, who was Lieutenant-Governor of New Zealand. At that time New Zealand was a dependent colony of New South Wales.
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.
British culture in New Zealand has been significantly influenced by Maori and other Polynesians. Scottish influences are strong, mainly in the South Island. In general, early immigrants from other parts of Europe and Asia, and World War II refugees (particularly the Dutch) were readily assimilated.
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.
