Maroa Caldera
	Maroa Caldera approximate location and boundaries contained within the older Whakamaru Caldera. The Ohakuri Caldera which had a paired eruption with the Rotorua Caldera is to its north and was not recognised as a separate caldera historically. To its west is the oldest Mangakino Caldera of the old Taupō Rift (yellow shading). Also shown is the modern Taupō Rift (red shading), Hauraki Rift (purple shading) and landmarks of Lake Taupō and Lake Rotorua
