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 does possess the usual cultural activities such as theatre, dance, fine arts, classical and popular music and creative writing. However, due to the small population base and a lack of arts funding sources, many artists have struggled to sustain themselves economically, even though they may achieve popular success. For this reason many of New Zealand's best artists go overseas, especially to Australia, but also to Europe or America, so they can further their careers.
New Zealand has no native land mammals apart from some rare bats. Later Maori largely subsisted by cultivating the kumara, a type of sweet potato, which they had brought with them from Polynesia.
Because of its long isolation from the rest of the world, New Zealand has extraordinary flora and fauna. Until the arrival of the first humans just a millennium or two ago, 80% of the land was forested and, barring two species of bat, there were no non-marine mammals at all. Instead, New Zealand's forests were inhabited by a diverse range of birds (many of them flightless), reptiles, and insectssome of them almost the size of a mouse (see weta).
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.
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.
In 2004 it began discussing free trade with China, one of the first countries to do so.
In October 1990, the National Party again formed the government, for the first of three, three-year terms. In 1996 New Zealand elected its first MMP Parliament. The system was designed to increase representation of smaller parties in Parliament and appears to have done so. Since 1996, neither the National nor the Labour Party has had an absolute majority in Parliament, and for all but one of those years, the government has been a minority one. The current Labour government followed its November 1999 election success by outpolling National 41 per cent to 21 per cent in the July 2002 general election. Labour formed a coalition, minority government with Jim Anderton's Progressive Coalition, a left-wing party (subsequently named "Progressive Party") which holds two seats in Parliament.
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.
New Zealand has no formal, written constitution; the constitutional framework consists of a mixture of various documents (including certain acts of the United Kingdom and New Zealand Parliaments) and constitutional conventions. Most constitutional provisions became consolidated into the Constitution Act 1986. There have, at times, been proposals for a formal constitution, but there have not yet been any serious moves to adopt one.
