Auckland Branch

Who Are We?

  • The Geoscience Society of New Zealand is an incorporated society which encourages the advancement of the earth sciences in New Zealand. Membership is open to all people interested in the pursuits of the Society.
  • The Auckland Branch is one of seven local branches who organise illustrated lectures, discussion meetings, field trips and social events.
  • The Branch has two different membership types - membership of the national body (GSNZ) and membership of the Auckland branch section - GeoClub. Some belong to one or the other and some belong to both.
  • Society membership entitles you to receive the GSNZ Newsletter, Branch newsletters and benefit from discounts.
  • GeoClub membership entitles you to a monthly GeoClub Newsletter by snail or email with information of upcoming talks and field trips (membership form and cost on page 3).

GeoClub: Bruce Hayward - or Hugh Grenfell -


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?


Over half the audience at the Hochstetter Lecture in August were Geoclubbers. Dr Chris Bromley spoke about New Zealand's geothermal resources and how they have been exploited for renewable energy and might be further developed in the future. He argued that better modelling of the geothermal systems should allow even those that are protected for their surface features to also be exploited. Many thanks to Chris and organizer Jennifer Eccles.
The superb sunny weather encouraged 20 geoclubbers to join our trip around the complex structural geology of the Waitematas at Takapuna Head and to have a picnic lunch at the beach. Thanks to leader Bruce Hayward. The GeoClub pot-luck dinner was a convivial gathering of 24 members with a fantastic array of food in spite of its truly pot luck nature. Thanks to Glenys and Bruce for hosting it.

NEXT MEETING: Epsom Community Centre, 200 Gillies Ave, Epsom. Opens at 7.15 PM for 7.30 PM start.

  • TUES 16th SEPT, 7.30 PM. "THE WATERVIEW TUNNEL - GEOTECHNICAL CHALLENGES". by Sian France (Beca), Stuart Cartwright (Tonkin & Taylor) and Bevan Hill (Parsons Brinkerhoff).
    The Waterview Connection is the largest roading project ever undertaken in New Zealand. It involves construction of 4.8km of motorway, half of which will be underground in Australasia's largest road tunnel being constructed using a custom-built tunnel boring machine (TBM) called Alice (the 10th largest of its kind). The alignment passes through basaltic lava flows, compressible alluvium, soft Waitematas and harder Parnell Grit, all within a densely urbanized area. Representatives of the Well-Connected Alliance geotechnical team will present a summary of the project geology and discuss some of the implications and challenges for design and construction.
  • TUES 21st OCT, 7.30 PM. "Limestones and limestone dykes on the Chatham Islands - the influence of basaltic volcanism on carbonate sedimentation" by Prof Cam Nelson (Waikato University).
