New Zealand is known world-wide for its outstanding geothermal attractions. The Waikato region contains 70 per cent of New Zealand’s geothermal systems.
Our geothermal resource includes:
Geothermal areas are valued for their vast and largely untapped quantities of thermal energy, mineralised fluids and increasingly for their:
New Zealand extracts 19 percent of its primary energy supply from geothermal sources, most of it from the Waikato region1. This figure is expected to increase to 30 percent by 20302. Geothermal energy provides about 13 percent of our national electricity supply, most of it coming from the seven geothermal power stations in the Waikato region1. In addition, in the Waikato region, about 40 separate industries, accommodation facilities and tourist facilities take small or medium quantities of heat or fluid.
New Zealand’s geothermal features are major tourist attractions for both domestic and international visitors, and are the single most popular sight-seeing destination for overseas visitors 3. In 2010, there were more than two and a half million visits to geothermal attractions in the Waikato region4.
Geothermal surface features are under threat in the Waikato. The most obvious indicator of the ill health of our natural geothermal features is the loss of rare features such as geysers, flowing springs and threatened plants.
Since the 1950s three quarters of New Zealand’s geysers have been lost, including features at Wairakei (through extraction of geothermal water) and Orakeikorako (drowned when the Ohakuri hydrodam was built).
Other damage to sensitive surface features and ecosystems has occurred, for example from:
Waikato Regional Council wants to protect our geothermal resources while allowing for the efficient use of them. To do this we are:
