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.
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.
New Zealand has a unicameral Parliament, the 120-seat House of Representatives. Since 1996, New Zealand has used the mixed member proportional (MMP) system, under which each MP is either elected by voters in a single-member (First Past the Post electoral system) constituency or appointed from party lists. Several seats are currently reserved for members elected on a separate Maori roll. However, Maori may choose to vote in and to run for the non-reserved seats, and several have entered Parliament in this way. Parliaments have a maximum term of three years, although an elections can be called earlier.
The three "R's" of New Zealand culture are Rugby, Racing and beeR. This cultural image probably has its origins in colonial agricultural New Zealand, when hard farm work such as harvesting, shearing and droving took place in hot summer conditions. The large number of soldiers who left New Zealand to fight in the First and Second World Wars and their subsequent socialising have contributed to this image.
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).
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.
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 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 (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.
For a variety of reasons many Maori and Pacific people have been socially disadvantaged, forming an underclass in some areas. Cultural considerations for both Maori and Pacific people now have a significant influence on educational, medical and social organisations, particularly in areas with high concentrations of these population groups.
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.
The South Island contained most of the white population until around 1900 when the North Island again took the lead and has supported an ever greater majority of the country's total population through the 20th century and into the 21st.
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's head of state is the Queen of New Zealand, currently Elizabeth II. The New Zealand monarchy has been distinct from the British monarchy since the New Zealand Royal Titles Act of 1953, and all Elizabeth II's official business in New Zealand is conducted in the name of the Queen of New Zealand, not the Queen of the United Kingdom. In practice, the functions of the monarchy are conducted by a Governor-General, appointed on the recommendation of the Prime Minister.
