Auckland City was a New Zealand city in the Auckland urban area, covering the central isthmus and most of the islands of the Hauraki Gulf. It included the Auckland CBD – a major financial and commercial centre – and a number of suburbs.
It was formerly a local authority district that was governed by Auckland City Council; it lay within the wider Auckland Region, which was governed by Auckland Regional Council. Auckland City was disestablished as a local government district on 1 November 2010, when Auckland City Council was amalgamated with other councils of the Auckland Region into the new Auckland Council. The local government district was the most populous district in the country, with a population of 450,000 at 30 June 2010. In 2009, Auckland was rated the fourth-best place to live in the world, in human resources consultancy Mercer's annual survey.
