New Zealand's geothermal resources

georthermal hero main

New Zealand has a large supply of geothermal energy, particularly across a wide strip in the central North Island known as the Taupō Volcanic Zone (TVZ).

Geothermal Resources

The TVZ is one of the most volcanically-active areas in the world. It includes two large caldera (collapsed) volcanoes (Taupo and Okataina), dome volcanoes (Ruapehu, Tongariro, Ngauruhoe and Whakaari/White Island), and zones of molten rocks between Ruapehu and Kawerau.
