Whakarewarewa geothermal field near Rotorua |
In the late 1980s, the Government shut down hundreds of geothermal bores around Rotorua after several hot springs ran dry.
GNS Science staff monitoring pools at the Whakarewarewa geothermal field say the Papakura Geyser appears to be recovering.
The Whakarewarewa Lands Trust says the regional council should review the geothermal field, and consider opening it to new methods of drilling which extract heat without taking water.
However, GNS vulcanologist, Brad Scot, advocates maintaining the status quo, saying the new drilling techniques are not well tested.
