New Zealand has a population of slightly over 4 million. About 80% of the population is of European descent. Maori people are the second largest ethnic group (14.7%). Between the 1996 and 2001 censuses, the number of people of Asian origin (6.6%) overtook that of Pacific Islanders (6.5%) (note that the census allowed multiple ethnic affiliations).
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.
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.
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.
The country is internationally recognised as achieving extremely well on a medals-to-population ratio at Olympic Games and Commonwealth Games.
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.
Since 1876, local government has administered the various regions of New Zealand. Due to its colonial heritage, New Zealand local government was modelled fairly closely on British local government structures, with elected city, borough, and county councils. Over the years some of these councils merged or had boundary adjustments by mutual agreement, and a few new ones were created. In 1989, the government completely reorganised local government, implementing the current two-tier structure of regional councils and territorial authorities.
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.
New Zealand has a unicameral Parliament, the 120-seat House of Representatives. Since 1996, New Zealand has used the mixed member proportional (MMP) system, under which each MP is either elected by voters in a single-member (First Past the Post electoral system) constituency or appointed from party lists. Several seats are currently reserved for members elected on a separate Maori roll. However, Maori may choose to vote in and to run for the non-reserved seats, and several have entered Parliament in this way. Parliaments have a maximum term of three years, although an elections can be called earlier.
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.
New Zealand became a British colony in 1840 following the signing of the Treaty of Waitangi between the Crown and Maori chiefs. The Crown was represented by William Hobson, who was Lieutenant-Governor of New Zealand. At that time New Zealand was a dependent colony of New South Wales.
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.
