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 is the most geographically isolated of all countries. Its closest neighbour Australia is 2,000 km to the northwest of the main islands across the Tasman Sea. The only landmass to the south is Antarctica, and to the north are New Caledonia, Fiji, and Tonga.
New Zealand comprises two main islands and a number of smaller islands. The South Island is the largest land mass, and is divided along its length by the Southern Alps, the highest peak of which is Mount Cook, at 3754 metres. There are 18 peaks of more than 3000 metres in the South Island. The North Island is less mountainous than the South, but is marked by volcanism. The tallest North Island mountain, Mount Ruapehu (2797 metres), is an active cone volcano.
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.
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 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.
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.
Of New Zealand's four million people, roughly three million live in the North Island and one million in the South Island. These islands are among the largest in the world and the combined land area is comparable to the British Isles or the US state of Colorado. Along with Aotearoa, another Maori name for New Zealand was Niu Tireni, a transliteration of the English name.
During the late 1980s, the New Zealand Government sold a number of major trading enterprises, including its telecommunications company, railway network, a number of radio stations and two financial institutions in a series of asset sales. Although the New Zealand Government continues to own a number of significant businesses, collectively known as State-Owned Enterprises (SOEs), they are operated through arms-length shareholding arrangements as stand alone businesses that are required to operate profitably, just like any privately owned enterprise. Various items of protective legislation establish business objectives yet prevent shareholding governments from having influence over day to day operations of the business.
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.
