Geography
Pukewairiki is one of the oldest known volcanoes of the Auckland Volcanic Field, having erupted an estimated 130,000 years ago.[1] It 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. In the past it has erroneously been called Pukekiwiriki, which is the name for Red Hill, Papakura.
The crater is located in Highbrook Park, a public park in East Tāmaki, Auckland on the shores of the Ōtara Creek.[1]
