West Auckland (Māori: Te Uru o Tāmaki Makaurau) is one of the major geographical areas of Auckland, the largest city in New Zealand. Much of the area is dominated by the Waitākere Ranges, the eastern slopes of the Miocene era Waitākere volcano which was upraised from the ocean floor, and one of the largest regional parks in New Zealand. The metropolitan area of West Auckland developed on the lands between the Waitākere Ranges to the west and the upper reaches of the Waitematā Harbour to the east, in areas such as Massey, Henderson, New Lynn and Glen Eden.
