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.
The judiciary consists of the Supreme Court of New Zealand, the Court of Appeal of New Zealand, the High Court, the District Courts, and other courts and tribunals. Some Judges may sit on more than one.
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 has a modern, developed economy. Its primary export industries are agriculture, horticulture, fishing, forestry and information technology. There are also substantial tourism and export education industries. The film and wine industries are considered to be up-and-coming.
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.
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.
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.
In 2004 it began discussing free trade with China, one of the first countries to do so.
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.
Political separation of the two islands was an issue in the 1860s. The more populous North Island was riven by war and political turmoil while the South Island was prospering, especially after gold was discovered (1861) at Gabriel's_Gully in Central Otago. The South Island grew very tired of financially supporting the North Island while receiving very little in return. The feeling was particularly bitter between Auckland and Otago where Dunedin journalist, Julius Vogel began a strong campaign to make the South Island completely independent. The matter was put to a vote in Parliament on September 19, 1865. Seventeen members voted for separation and 31 for unity, so New Zealand remained united. Vogel later became Prime Minister of a united New Zealand.
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.
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.
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).
