The Waitākere Ranges is a mountain range in New Zealand. Located in West Auckland between metropolitan Auckland and the Tasman Sea, the ranges and its foothills and coasts comprise some 27,720 hectares (68,500 acres) of public and private land. The area, traditionally known to Māori as Te Wao Nui o Tiriwa (The Great Forest of Tiriwa), is of local, regional, and national significance. The Waitākere Ranges includes a chain of hills in the Auckland Region, generally running approximately 25 kilometres (16 mi) from north to south, 25 km west of central Auckland. The ranges are part of the Waitākere Ranges Regional Park.
