Today New Zealand has 12 regional councils for the administration of environmental and transport matters and 74 territorial authorities that administer roading, sewerage, building consents, and other local matters. The territorial authorities are 16 city councils, 57 district councils, and the Chatham Islands Council. Four of the territorial councils (one city and three districts) and the Chatham Islands Council also perform the functions of a regional council and thus are known as unitary authorities. Territorial authority districts are not subdivisions, as such, of regional council districts and a few of them straddle regional council boundaries.
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.
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.
Because many New Zealanders have to go elsewhere in the world to achieve fame and fortune, New Zealand society is keen to attribute famous people as being New Zealanders, however short their residency in New Zealand might have been. While being born in New Zealand is an absolute qualification for being identified as a New Zealander, attendance at a New Zealand school, or being a permanent resident in New Zealand when fame is initially achieved also qualifies, irrespective of national origin. This sometimes leads to famous people being identified as coming from both New Zealand and another country - often Australia, such as the pop group Crowded House, the actor Russell Crowe, and the Pavlova dessert, all of which are claimed by Aussies and Kiwis as 'theirs'. However, New Zealanders are generally proud to have disowned controversial figures such as Sir Joh Bjelke-Petersen.
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 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.
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.
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.
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 usual climate throughout the country is mild, mostly cool temperate to warm temperate, with temperatures rarely falling below 0°C or rising above 30°C. Conditions vary from wet and cold in Southland and the West Coast of the South Island, where most of the country's rain falls, to subtropical in Northland. In Wellington the average minimum temperature in winter is 5.9°C and the average maximum temperature in summer is 20.3°C.
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 insects—some of them almost the size of a mouse (see weta).
For a variety of reasons many Maori and Pacific people have been socially disadvantaged, forming an underclass in some areas. Cultural considerations for both Maori and Pacific people now have a significant influence on educational, medical and social organisations, particularly in areas with high concentrations of these population groups.
