Rugby as a sport is closely linked to New Zealand's national identity. The national rugby team is called the All Blacks and has the best winning record of any national team in the world. The style of name has been followed in naming the national team in several other sports. New Zealand's national sporting colours are not the colours of its flag, but are black and white (silver). The silver fern is a national emblem worn by New Zealanders representing their country in sport. The haka—a traditional Maori challenge—is often performed at sporting events. The All Blacks traditionally perform a haka before the start of play.
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).
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.
Since 1984 successive governments have engaged in major economic restructuring, transforming New Zealand from a highly protectionist and regulated economy to a liberalised, free-trade economy. Despite periods of dynamic growth in the mid 1980s and early '90s, average yearly economic growth has been poorer than expected and is highly reliant on massive levels of immigration to boost GDP. However, since 1999 New Zealand has enjoyed a period of relatively strong and sustained growth.
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).
New Zealand was originally settled by waves of Polynesians, some time between 1000 and 1300, although some evidence now suggests an earlier settlement. Those in the main islands of New Zealand became the Maori people. Separate settlement of the tiny Chatham Islands in the east of New Zealand produced the Moriori people, but it is uncertain whether they went there direct from Polynesia or were mainland Maori who ventured eastward.
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.
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.
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.
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.
God's Own Country, or Godzone, is generally accepted, by New Zealanders if nowhere else, as the alternative name for New Zealand. God's Own Country was the title of a poem about New Zealand written by Thomas Bracken about 1890. (He also wrote God Defend New Zealand, which became the country's second national anthem). It was a favourite saying of Richard John Seddon, Premier of New Zealand for 13 years (1893-1906).
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.
