West Auckland 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 now one of the largest regional parks in New Zealand. The metropolitan area of West Auckland developed between the Waitākere Ranges to the west and the upper reaches of the Waitematā Harbour to the east. It covers areas such as Glen Eden, Henderson, Massey and New Lynn.
