Self-government was granted to the settler population in 1852, under the UK Parliament's New Zealand Constitution Act 1852, with a General Assembly consisting of an appointed Legislative Council and an elected House of Representatives. In 1867, Maori won the right to a certain number of reserved seats in parliament. During this period, the livestock industry began to expand, and the foundations of New Zealand's modern economy took shape. By the end of the 19th century, improved transportation facilities made possible a great overseas trade in wool, meat, and dairy products.
New Zealand was featured as the setting for "Middle Earth" in the renowned early 21st century trilogy of films based on Tolkien's Lord of the Rings books. It has brought an additional interest in tourism to the nation.
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.
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.
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.
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.
Although less obvious today, in the past team sports, particularly Rugby football, gambling on horse races, and sharing a beer after a hard day's work with some good friends or work mates have been significant images of New Zealand life. This predominantly working-class male cultural image has previously been so strong that it has overshadowed other, perhaps higher, cultural aspects of New Zealand society.
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.
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.
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.
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.
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.
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.
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.
