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).
Confronted like Australia with the strategic implications of Britain's 20th-century eclipse as a world power of the first rank, New Zealand joined with Australia and the United States in the ANZUS pact in 1951, but the US suspended its defence commitments to the country in 1986 after the then Labour government banned nuclear-powered or armed ships from New Zealand ports.
Kiwi (usually capitalised) has been applied to and adopted by New Zealanders as a nickname for themselves and as an adjective for their culture. It originates from kiwi (usually uncapitalised), the Maori word for several species of flightless birds endemic to New Zealand. The plural form for New Zealanders is always Kiwis. The plural forms for the birds are the anglicised kiwis or, following the Maori language, kiwi without an s.
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.
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.
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.
The country is internationally recognised as achieving extremely well on a medals-to-population ratio at Olympic Games and Commonwealth Games.
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 hakaa traditional Maori challengeis often performed at sporting events. The All Blacks traditionally perform a haka before the start of play.
The remoteness of many parts of New Zealand and the distance of the country from much of the developed world meant that things that were easily obtainable in other parts of the world were often not readily available locally. New Zealand has only recently experienced economic development outside farming, so traditionally, Kiwis are jacks-of-all-trades to some extent, willing to roll up their sleeves and have a go. Most highly industrialised countries produce experts trained in narrow fields of specialisation, but New Zealand professionals are often generalists as well. This reputation often makes New Zealanders uniquely valued employees in overseas organisations.
While British culture predominates within the country, Maori culture is increasingly being identified with New Zealand, due to haka displays by New Zealand sporting teams, and to tens of thousands of visitors who each year experience and film or photograph Maori culture events held at places such as Rotorua.
A number of New Zealand commentators have observed that there is no culture in New Zealand. This has led to protests from those who believe that there is a uniquely definable New Zealand culture. Perhaps one of the more memorable protests was the 1980 song "Culture" by The Knobz after outspoken Prime Minister Sir Robert Muldoon stated that New Zealand pop music was not part of the New Zealand cultural scene.
The Cabinet, which is responsible to Parliament, exercises executive authority. (The Cabinet forms the practical expression of a formal body known as the Executive Council.) The Prime Minister, as the leader of the political party or coalition of parties holding the majority of seats in the House of Representatives, leads the Cabinet. All Cabinet Ministers must be Members of Parliament (MPs) and are collectively responsible to it.
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).
New Zealand's most popular sports are rugby (primarily rugby union but also rugby league), soccer (the most popular sport amongst children), cricket, and netball (the sport with the most players); golf, tennis, rowing and a variety of water sports, particularly sailing. Snow sports such as skiing and snowboarding are also popular. Equestrian sportsmen and sportswomen make their mark in the world (Mark Todd being chosen international "Horseman of the Century"), and all the way down to the juniors at pony club level.
