Motutapu Island (or simply Motutapu) is a 1,509 ha (3,730 acres) island in the Hauraki Gulf to the northeast of the city of Auckland, New Zealand. The island is part of the Hauraki Gulf Maritime Park. The island is now linked by an artificial causeway to the much younger volcanic island cone of Rangitoto. Prior to the emergence of the volcano, the island had been extensively occupied by Māori for over 100 years. The eruption, some 700 years ago, destroyed their settlements, but there is circumstantial evidence that some of the residents may have escaped the destruction, presumably by waka (canoe). Of the many archaeological sites recorded, one, the Sunde Site (Puharakeke), shows human and dog footprints preserved in solidified ash. These were protected from erosion by a layer of ash from the next eruption.
