About
Purchas Hill (also Te Tauoma) is one of the volcanoes in the Auckland volcanic field.
Purchas Hill was a twin-cratered scoria cone around 50 metres high, located north of Maungarei / Mount Wellington, before it was predominantly quarried away. The scoria cone sat in the middle of its large explosion crater with a surrounding tuff ring. It erupted about 10,000 years ago, shortly before the eruption of its larger neighbour, Mount Wellington.
