Auckland (Tāmaki Makaurau) is one of the sixteen 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 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.
On the mainland, the region extends from the mouth of the Kaipara Harbour in the north across the southern stretches of the Northland Peninsula, through the Waitākere Ranges and the isthmus of Auckland and across the low-lying land surrounding the Manukau Harbour, ending within a few kilometres of the mouth of the Waikato River. It also includes the islands of the Hauraki Gulf. It is bordered in the north by the Northland Region, and in the south by the Waikato region. The Hunua Ranges and the adjacent coastline along the Firth of Thames were part of the region until the Auckland Council was formed in late 2010, when they were transferred to the Waikato region. In land area the region is smaller than all the other regions and unitary authorities except Nelson.
The region's coastline is long. It has about of rivers and streams, about 8 percent of these in urban areas. Its highest point is the summit of Little Barrier Island, at 722 metres.
