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.
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).
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.
Although less obvious today, in the past team sports, particularly Rugby football, gambling on horse races, and sharing a beer after a hard day's work with some good friends or work mates have been significant images of New Zealand life. This predominantly working-class male cultural image has previously been so strong that it has overshadowed other, perhaps higher, cultural aspects of New Zealand society.
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).
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.
New Zealand functions as a constitutional monarchy with a parliamentary system of government. The basic system is closely patterned on that of the United Kingdom, although a number of significant modifications have been made. The head of state is Queen Elizabeth II, but actual government is conducted by a Prime Minister and Cabinet drawn from an elected Parliament.
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 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.
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.
