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.
The total land area of New Zealand, 268,680 km², is somewhat less than that of Japan or of the British Isles, and slightly larger than Colorado in the USA. The country extends more than 1600 km along its main, north-northeast axis.
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.
Partly because of its geographical isolation from neighbouring countries, and partly because of the number and location of numerous uninhabited islands belonging to it, New Zealand's Exclusive economic zone of marine resources was the world's fifth largest, at 4.2 million square kilometres in the year 2000 (according to New Zealand's National Institute of Water and Atmospheric Research).
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.
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).
New Zealand is a unitary state rather than a federation — regions are created by the authority of the central government, rather than the central government being created by the authority of the regions. Local government in New Zealand has only the powers conferred upon it by Parliament. These powers have traditionally been distinctly fewer than in some other countries. For example, police and education are run by central government, while the provision of low-cost housing is optional for local councils. Many of them used to control ports and gas and electricity supply, but nearly all of that was privatised in the late 20th century.
British culture in New Zealand has been significantly influenced by Maori and other Polynesians. Scottish influences are strong, mainly in the South Island. In general, early immigrants from other parts of Europe and Asia, and World War II refugees (particularly the Dutch) were readily assimilated.
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.
Confronted like Australia with the strategic implications of Britain's 20th-century eclipse as a world power of the first rank, New Zealand joined with Australia and the United States in the ANZUS pact in 1951, but the US suspended its defence commitments to the country in 1986 after the then Labour government banned nuclear-powered or armed ships from New Zealand ports.
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.
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.
Sporting and outdoor activities still play a significant part in the recreation of New Zealanders. Participation in a sport, rather than mere spectating, is considered a worthy pursuit. Team sports and sporting abilities are generally held in high regard, with top-performing players often becoming celebrities. However, New Zealanders can often be scathing when national sports teams and athletes lose.
New Zealand is a country of two major islands and a number of smaller islands in the southwestern Pacific Ocean. A popular Maori name for New Zealand is Aotearoa, often translated as The Land of the Long White Cloud. New Zealand is a parliamentary democracy and a Commonwealth Realm. New Zealand is responsible for the self-governing states of the Cook Islands and Niue and administers Tokelau and the Ross Dependency.
