What is "GeoClub'?

  • Established in 1992 at Auckland Museum the GeoClub is now part of the Auckland Branch of the Geoscience Society of New Zealand at Auckland University. The Club is a mix of enthusiastic amateurs and professionals who share a common interest in the study and understanding of Auckland's geology and fossils and has a membership of approximately 100.
  • No previous knowledge or understanding of geology is required to become a member, although most of our members started by taking an adult education course or a geology paper at University. The main requirement is an enthusiasm to understand something about the long history of the earth and our region.
  • Recent Club field trips have included visits to Hokianga, East Cape, Rotorua, Port Waikato, Waihi Gold Mine, Puketotara Peninsula, Kawau Island, the Miranda coast, Piha, Browns Island, Pollen Island, Whangaparoa, the Hillsborough coast, Queens Street building stones, Takapuna fossil forest to mention a few.

  • Geology is a hobby that families and people of all ages can enjoy. It gets you out into the open air and is a great way to exercise. It takes you to fascinating places you have never visited before and above all you will start seeing the landscape with new eyes. No longer will you just see sheep grazing on hills. You will start to see the lava flows, the fault lines, the folded strata that control the shape of the hills, ancient river terraces and coastal plains.

What do we do?

  • Monthly meetings at the Epsom Community Centre, 200 Gillies Ave with lectures and slide shows. Parking is available (see below ) with easy access from the motorway. Books and pamphlets on New Zealand geology available at wholesale prices. Expert assistance available to help identify your problem rocks, minerals or fossils.
  • Frequent field trips of half or full day duration in the weekends throughout the year. Car-pooling is encouraged. Periodic long weekend field trips to interesting geology further from Auckland, with costs kept low with budget accommodation.


What's On?


Sasha Nolden gave us an entertaining and interesting June meeting, telling us all about his research on Hochstetter and his visit to NZ and showing some of the bounty of previously unseen historic records and diaries he has sleuthed out. Liz Hoskin began by showing us images of the enormous flood damage done earlier that week around northern Coromandel, where we visited a few weeks earlier. Many thanks to both speakers. In a short gap between the rains and winds, 25 members made the most of one of the nicer days in winter to explore the east side of Rangitoto Island and the Motutapu coastline to Emu Pt. The highlights were visiting lava caves recently discovered by one of our leaders, Peter Crossley; the size of water-rounded basalt boulders eroded from Rangitoto in just 500 years; the polished greywacke (argillite) cobble beaches and several huge greywacke boulders on both sides of Emu Pt (how did they get there?); and for the 7 that made it that far - Peter Scott's clastic dike walls. Many thanks to the two Peters and Bruce for organizing and leading the trip.
