My husband and I are coming to NZ in Feb/March next year. We will be based in Tauranga. Our main interest is in the geology of NZ and in particular the volcanic area around Oranui (?). I think that is near Lake Taupo. Any suggestions of who to contact to find out more about the geology of NZ generally would be appreciated. Also - is distance from Tauranga to Lake Taupo going to make going and returning in a day a problem? Thanks for any help given.
