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.
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.
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.
Immigration policy in New Zealand has often been controversial, with some politicians claiming that the pace of immigration has been too rapid for New Zealand to absorb, and that recent immigrants are having trouble adapting to the New Zealand society. This position is seen by others as a cynical appeal to xenophobic sentiment in order to gain votes near election time, and these views are not widely supported by the general population.
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.
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 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.
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).
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.
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.
While New Zealand men often take pride in being 'strong, silent types', this attitude may have a downside in contributing to New Zealand having one of the highest suicide rates among young males in the industrialised world.
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.
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 is world-famous among glider pilots for hosting the 1995 Gliding World Cup at Omarama in North Otago near the centre of the South Island. The Southern Alps are known for the excellent wave soaring conditions. Steve Fossett has recently tried to beat the world gliding altitude record there.
