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 (Geoscience Society of New Zealand) and membership of the Auckland branch section - GeoClub. Some belong to one or the other and some belong to both.
  • Geoscience Society membership entitles you to receive the GSNZ Newsletter, Branch newsletters and benefit from discounts. For more information go here.
  • GeoClub membership entitles you to a monthly GeoClub Newsletter by snail or email with information of upcoming talks and field trips. For more information about GeoClub go here and for the GeoClub membership form go here .

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?


From all accounts PhD student Geoff Lerner gave an extremely interesting talk at the August Club meeting, on his recent discoveries about Taranaki Volcano. In late August, 27 members contributed to a sumptuous pot-luck dinner and then tested their geoskills in the annual club geoquiz. Many thanks to Bruce and Glenys for hosting the dinner once again this year. On a weather-challenged Sun early in September, 14 members turned out to join the search for Christine's basalt protokarst - the unanimous conclusion was that the irregular surfaces on some of the boulders could plausibly have been formed by solution but they differ considerably from the classic examples in dense basalt in Northland and "we do not understand" the weathering processes at Otuataua. Most of us continued on to circumnavigate and explore the remains of Maungataketake Volcano. After a mammoth 4 hour cross-country walk, Peter Turnwald reported that he had achieved 20,000 steps and Hugh used google to calculate that we had walked 9540 metres. Rumours are that George is still out there walking.

Geocene 20 was published and disseminated last month
