Kohuora, located in the suburb of Papatoetoe,[1] is one of the volcanoes in the Auckland volcanic field in the North Island of New Zealand.

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,[2] and the irregular V-shape of the complex indicated that there were at least three explosion crater vents.[3] Peat and lacustrine deposits layer on top of the volcanic soil of the Kohuora.[3]

The Kohuora wetland is an important habitat for native bird and plant species, including Carex subdola, a sedge rare in the Auckland area.[3]

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.[4][5] The name Kohuora means "mists of life", and the volcano is occasionally referred to as Kohuaroa ("The cauldron of life").[3]
