Reporoa caldera
 The Reporoa caldera is a 10 km by 15 km caldera in New Zealand's Taupo Volcanic Zone. It formed some 230000 years ago in a large eruption that deposited the approximately 100 km3 Kaingaroa Ignimbrites. It contains three rhyolitic lava domes (Deer Hill Kairuru and Pukekahu) and the active Reporoa geothermal field. The Waiotapu geothermal area lies just north of the caldera rim while the Broadlands thermal area lies to the south.
