One Tree Hill

Maungakiekie / One Tree Hill is a 182-metre volcanic peak and Tūpuna Maunga in Auckland, New Zealand. It is an important place culturally and archeologically for both Māori and Pākehā. The suburb around the base of the hill is also called One Tree Hill. It is surrounded by the suburbs of Royal Oak to the west, and clockwise, Epsom, Greenlane, Oranga, and Onehunga. The summit provides views across the Auckland area, and allows visitors to see both of Auckland's harbours.

The scoria cones of the hill were erupted from three craters – one is intact and two have been breached by lava flows that rafted away part of the side of the scoria cone. Lava flows went in all directions, many towards Onehunga, covering an area of 20 square kilometres, making it the second largest of the Auckland volcanic field, behind Rangitoto Island. The volcano erupted approximately 67,000 years ago.
