Māori carving known as Pukaki



Pukaki was expertly crafted by Te Taupua of Ngati Whakaue from one large piece of totara timber, originating from the Ngongotaha Stream. The carving commemorates Ngati Whakaue's conquest of Pukeroa-Oruawhata. Pukaki is depicted holding his two warrior sons Wharengaro and Rangitakuku, while between his legs can still be seen the remnants of his wife Ngapuia.

New Zealand's 20 cent coins issued since 1990 feature a remarkable Maori carving. This is no generic image. Rather it is a reproduction of a specific carving of an 18th century Maori warrior leader called Pukaki, who was a Rangatira (Chief) of the Ngati Whakaue iwi of Te Arawa in the Rotorua district.
