Previous geophysical studies of the Tokaanu-Waihi hydrothermal system combined with recent measurements using new techniques have provided a large database from which a comprehensive resistivity boundary has been constructed. The mapped area with low resistivity coincides with that of demagnetized ground defined from an aeromagnetic survey carried out in 1997. By combining the geophysical information with comprehensive geochemical studies it is possible to map the extent and the hydrological structure of the system including the position of the upflow beneath Hipaua.
