Purchas Hill was a twin-cratered scoria cone around 50 metres high, located north of Maungarei / Mount Wellington, before it was predominately 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.[1]

History
A map of the Auckland volcanic field by Hochstetter from 1859, showcasing Purchas Hill amongst other volcanoes.

In the mid 1800s, geologist Ferdinand von Hochstetter named the mountain after the Reverend Dr Arthur Guyon Purchas (1821-1906), in gratitude for his help with geological work on the field.[1]

The scant remnants of Purchas Hill lie on what is largely a wasteland in the suburb of Stonefields in Auckland.[2]

The road Purchas Hill Drive is located where Purchas Hill used to be.
