The New Zealand Geothermal Analytical Laboratory is based at GNS Science in Wairakei, Taupo. Isotopic analysis is carried out at GNS Science’s National Isotope Centre in Wellington.


As part of GNS Science’s Wairakei Research Centre, the New Zealand Geothermal Analytical Laboratory was established in late 1950’s following the development of the Wairakei geothermal power station. In 2012 the lab had a full up-grade, including facilities and equipment, enabling analyses of a vast array of geothermal and groundwater samples to be performed.
