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?


Phillip Kirk gave an outstanding lecture at our Feb meeting on the geology of Hong Kong and in particular on how the unusual sediment-filled paleokarst developed in marble inclusions in a pluton caused havoc with a proposed high-rise development in reclaimed land. In February 24 members drove to Kauaeranga Valley to examine some of the more readily accessible geology and kauri industry relics near the end of the road. With the dry weather the river was exceptionally low but Peter D-K still managed to get damp in a small tributary. At the beginning of March on the hottest day of the year, 30 members used hire vans to get around Waiheke Island and visit Blackpool pillow lava, Oneroa basal Waitematas and Stoney Batter karst basalt and WW2 battery. Lunch was had under pohutukawa on idyllic Oneroa Beach where four of the group indulged in a swim. Many thanks to Phil Kirk, Bruce Hayward for leading the trips, Helen Holzer for taking bookings, and Garry Carr, Murray Baker and Kelvin Stace for driving vans.
