Waiatarua is a small settlement near the top of the Waitākere Ranges in West Auckland, close to the junction of Scenic Drive, West Coast Road and Piha Road to Piha and runs east until the junction of Scenic Drive and Mountain Road. Surrounded by native bush in the Centennial Memorial Park and the water catchment area, Waiatarua is over 300 metres above sea level and some houses are over 400 metres above sea level (higher than the Auckland Sky Tower). Waiatarua means “song of two waters”, possibly referring to the ability to see both the wildwest coast, and the still, sparkling waters of the Manukau and Waitemata harbours from certain points in the area.
