Pukewairiki

Pukewairiki tuff crater.

Eroding tuff layers with embedded basaltic rock, Pukewairiki.

Pukewairiki is a volcano in the Auckland volcanic field in New Zealand.

Pukewairiki has an explosion crater around 500 m wide, and a tuff ring up to 30 m high, which has been eroded away on the south-western side. The northern side had a terrace eroded into at a time of higher sea-level during the Last Interglacial and thus the volcano is older than 130,000 yrs. In the past it has erroneously been called Pukekiwiriki, which is the name for Red Hill, Papakura.
