Geothermal Energy Resources in New Zealand

Geothermal energy is an important contributor to New Zealand’s electricity and heat supply, contributing 11% to total primary energy supply.

This map shows the major geothermal areas in New Zealand. Low temperature areas are used mainly for recreational purposes. The high temperature areas of the Taupo Volcanic Zone and Ngawha geothermal field have temperatures above 200 degrees Celsius and are the main geothermal electricity generation regions of New Zealand.

Distribution of geothermal waters in New Zealand

New Zealand's geothermal waters can generally be separated (but not always), on the basis of their temperature, geological location and chemistry, into two main groups:

Low-Temperature Waters with temperatures of between about 20°C (ambient) and about 100°C, associated with active faults.
High-Temperature Waters with temperatures greater than 100°C, associated with areas of active volcanism.

Central part of the North Island

The map shows the location of the known high-temperature volcanic geothermal systems (Hunt & Bibby, 1992; Mongillo & Clelland, 1984).
