Geology and geography

The Kohuora complex is a freshwater wetland found in a tuff ring, that has an explosion crater around 600 metres wide and 30 metres deep. Kohuora erupted an estimated 34 million years ago,{{cite journal |last1=Hopkins |first1=Jenni L. |last2=Smid |first2=Elaine R. |last3=Eccles |first3=Jennifer D. |last4=Hayes |first4=Josh L. |last5=Hayward |first5=Bruce W. |last6=McGee |first6=Lucy E. |last7=van Wijk |first7=Kasper |last8=Wilson |first8=Thomas M. |last9=Cronin |first9=Shane J. |last10=Leonard |first10=Graham S. |last11=Lindsay |first11=Jan M. |last12=Németh |first12=Karoly |last13=Smith |first13=Ian E.

Peat and lacustrine deposits layer on top of the volcanic soil of the Kohuora.

The Kohuora wetland is an important habitat for native bird and plant species, including Carex subdola, a sedge rare in the Auckland area.

History

The volcano, alongside Māngere Lagoon, Waitomokia, Crater Hill, Pukaki Lagoon and Robertson Hill, is one of the volcanic features collectively referred to as Nga Tapuwae a Mataoho ("The Sacred Footprints of Mataoho"), referring to the deity in Tāmaki Māori myths who was involved in their creation.{{Cite web | title = The History of Our Marae |url=https://makauraumarae.co.nz/about/our-history/ | publisher = Makaurau Marae | access-date = 1 September 2021}}{{cite Q|Q58677091}} The name Kohuora means "mists of life", and the volcano is occasionally referred to as Kohuaroa ("The cauldron of life").{{cite web|url=https://www.aucklandcouncil.govt.nz/arts-culture-heritage/heritage-walks-places/Documents/papatoetoe-heritage-trail.pdf |title=Papatoetoe Heritage Trail |date=2013 |publisher=Ōtara-Papatoetoe Local Board |access-date=31 March 2023}}
