A former territorial authority district in Auckland, New Zealand, that was governed by the Manukau City Council. The area is sometimes referred to as "South Auckland", although this term never possessed official recognition and does not encompass areas like East Auckland, which was within the city boundary. It was a relatively young city, both in terms of legal status and large-scale settlement – though in June 2010, it was the third largest in New Zealand and the fastest growing. In 2010 the entire Auckland Region was amalgamated under a single city authority, Auckland Council.
The name Manukau, from the Manukau Harbour west of the city, is of Māori origin, and means 'wading birds', although it has been suggested that the name of the harbour was also sometimes rendered as Mānuka, meaning a marker post with which an early chief is said to have claimed the area.
