Urban areas of New Zealand in the context of "Hastings, New Zealand"

The word city took on two meanings in New Zealand after the local government reforms of 1989. Before the reforms, a borough that had a population of 20,000 or more could be proclaimed a city. The boundaries of councils tended to follow the edge of the built-up area, so there was little difference between the urban area and the local government area. In 1989, the structure of local government in New Zealand was significantly reorganised. Almost all the new district councils and city councils were much larger in land area, and they covered both urban land and the surrounding rural land. Many locations that once had a "city council" are now governed by a "district council". Since 2002, an urban area must have at least 50,000 residents to be proclaimed a city.

The word city is used in a general sense to identify the urban areas of New Zealand, independent of local body boundaries. This informal usage is jealously guarded. The district government of the town of Gisborne, for example, adamantly described itself as the first "city" in the world to see the new millennium. Gisborne is governed by a "district council", though its status as a city is not generally disputed in New Zealand. Similarly, there is no "city council" in Auckland, though its status as a city is not generally disputed due to its considerable size.

Auckland (Māori: Tāmaki Makaurau) is one of the 16 regions of New Zealand, which takes its name from the eponymous urban area. The region encompasses the Auckland metropolitan area, smaller towns, rural areas, and the islands of the Hauraki Gulf. Containing 34 percent of the nation's residents, it has by far the largest population and economy of any region of New Zealand, but the second-smallest land area.

On 1 November 2010, the Auckland region became a unitary authority administered by the Auckland Council, replacing the previous regional council and seven local councils. In the process, an area in its southeastern corner was transferred to the neighbouring Waikato region. Since then, the Auckland Council has introduced a system of local boards to divide the region for local government.
