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.
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 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.
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.
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.
The Cabinet, which is responsible to Parliament, exercises executive authority. (The Cabinet forms the practical expression of a formal body known as the Executive Council.) The Prime Minister, as the leader of the political party or coalition of parties holding the majority of seats in the House of Representatives, leads the Cabinet. All Cabinet Ministers must be Members of Parliament (MPs) and are collectively responsible to it.
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.
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.
Britain was motivated by the desire to forestall other European powers (France established a very small settlement on Banks Peninsula in the South Island at Akaroa also in 1840) and to end the lawlessness of European (predominantly British) whalers and traders. Maori chiefs were motivated by the promises of protection of their existing possessions (which was only partially carried out) and by the promise of protection against other Maori using muskets obtained from European whalers and traders (the Musket Wars of 1820-1835).
From the 1790s the waters around New Zealand were visited by British, French, and American whaling ships, whose crews sometimes came into conflict with Maori inhabitants. The arrival of traders and missionaries in the 1800s and 1810s added to local disputes. The first full-blooded European infant in the territory, Thomas King, was born in 1815 in the Bay of Islands. The initiation of a programme of large-scale settlement and land purchases in 1839 by the New Zealand Company, coupled with increasing French interest in the islands, finally prompted the British government to take control of the situation.
While New Zealand men often take pride in being 'strong, silent types', this attitude may have a downside in contributing to New Zealand having one of the highest suicide rates among young males in the industrialised world.
