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.
New Zealand's scenery has appeared in a number of television programmes and films. In particular, Hercules and Xena were filmed around Auckland, Heavenly Creatures in Christchurch. The Tribe is set and filmed here too. Peter Jackson shot the epic The Lord of the Rings trilogy in various locations around the country, taking advantage of the spectacular and relatively unspoiled landscapes, and Mount Taranaki was used as a stand-in for Mount Fuji in The Last Samurai. Other movies currently filming in New Zealand include King Kong and The Lion, the Witch and the Wardrobe.
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.
In 2004 it began discussing free trade with China, one of the first countries to do so.
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.
Christianity is the predominant religion in New Zealand, although over a quarter of the population has no religious affiliation. The main Christian denominations are Anglicanism, Presbyterianism, Roman Catholicism and Methodism. There are also significant numbers who identify themselves with Pentecostal and Baptist churches and with the Mormon church. The New Zealand-based Ratana church has many adherents among Maori. According to census figures, other significant minority religions include Hinduism, Buddhism and Islam.
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.
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.
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 imports much of its cultural material from overseas, particularly from Britain or the United States. Most successful Hollywood films screen on New Zealand cinema screens and New Zealand Television shows a lot of British and American television programmes. It is somewhat ironic that some of these programmes are now made in New Zealand but receive their first screening elsewhere. The New Zealand cinematographic industry is becoming one of the country's major export enterprises, with several major motion pictures being filmed on New Zealand locations recently, including the highly acclaimed film adaptation of Tolkien's "The Lord of the Rings" directed by the Kiwi Peter Jackson.
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.
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.
New Zealand is heavily dependent on trade—particularly in agricultural products—to drive growth, and it has been affected by global economic slowdowns and slumps in commodity prices. Since agricultural exports are highly sensitive to currency values and a large percentage of consumer goods are imported, any changes in the value of the New Zealand dollar has a strong impact on the economy.
