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 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 from north to south, 25 km west of central Auckland. The ranges are part of the Waitākere Ranges Regional Park. From 1 May 2018 the forested areas of the Waitākere Ranges Regional Park were closed, with some exceptions, while Auckland Council upgraded the tracks to dry foot standard protect the roots and to prevent the spread of kauri dieback, bacteria that affect kauri trees and prevents them from getting nutrients, effectively killing them. There is no cure. But Etymology The name Wai-tākere originally came from a rock located in Waitākere Bay near Te Henga (Bethells Beach). In Māori the name Te Wao Nui a Tiriwa ("The Great Forest of Tiriwa"), referred to all of the forested areas south from Muriwai and the Kaipara Harbour portage to the Manukau Harbour, while the name Hikurangi referred to the central and Western Waitākere Ranges, south of the Waitākere River. Geology The rugged upstanding topography is formed from erosion-resistant ancient volcanic conglomerate and lava flows laid down in eruptions from the large Waitākere volcano to the west 12–25 million years ago. The Waitākere Ranges and land south from Muriwai are the eastern slopes of the volcano, which were uplifted from the sea floor between 3 and 5 million years ago. Much of the rock that forms the ranges, such as the Piha Formation and Nihotupu Formation, are volcanic and marine conglomerate rocks. Many of the features of the ranges, such as Karekare, Te Toka-Tapu-a-Kupe / Ninepin Rock and Pukematekeo, are remnants of volcanic vents and plugs. Geography The western coastline of the ranges consists of cliffs exceeding , interspersed infrequently with beaches. The ranges are covered in native forest, most of which is in the process of regeneration since extensive logging and farming in the mid–late 19th and early 20th centuries. The highest point in the Waitākere Ranges, at , is Te Toiokawharu, in the southern part of the ranges, about north-east of Huia. The Scenic Drive follows a ridge
