Abstract
The current production of geothermal fluid from the Wairakei-Tauhara system exceeds the natural recharge of heat by a factor of 4.75. Even with this rate of heat abstraction Wairakei-Tauhara is expected to be able continue supplying the present amount of separated steam for at least another 50 years. The present paper considers the recovery of Wairakei-Tauhara after it is shut down, say in 2053. In particular it investigates how long will it take for Wairakei-Tauhara to fully recover to its original state and what changes will occur during the recovery process.
