Postulated volcanic caldera, within another older volcanic caldera in New Zealand
The Haroharo Caldera (Haroharo volcanic complex) is a 26 by 16 km (16.2 by 9.9 mi) postulated volcanic feature in Taupō Volcanic Zone of the North Island, New Zealand within the larger and older Ōkataina Caldera. Since 2010 further studies have tended to use the terms Haroharo vent alignment, Utu Caldera, Matahina Caldera, Rotoiti Caldera and a postulated Kawerau Caldera to the features assigned to it.[1] However the name is used in the peer reviewed literature to summarise and group these features based on gravitational and magnetic features.[2]: 14
