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).

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.

NEXT MEETINGS & FIELD TRIPS

At the July meeting we were treated to Ron Keam talking about the Tarawera eruption. Ron's knowledge of the Tarawera eruption is amazing and everyone learnt new things about various aspects of the eruption. For example the Pink and White terraces may have existed in their infancy prior to the Kaharoa eruption, but essentially were formed over the 550 yr period between 1314 AD and 1886 AD; and that the all humans within about 5 km of Rotomahana would have been incinerated by the base surge pyroclastic blast prior to the huge mud eruption from the old lake, that so deeply buried Te Ariki and other Maori villages. Many thanks for a great evening Ron. A small group of GeoClubbers joined leader Hugh Grenfell on his mystery KKK circuit (Karanghape, Kaitarakihi, Kakamatua) around the coast and back via the road with a visit to Spraggs Memorial thrown in. As usual the forecast was pretty meaningless and no rain eventuated, although some got a little wet from the bottom up instead for some reason. The early Miocene volcaniclastic sedimentary rocks of the Cornwallis Formation were amazingly varied and interesting. Thanks for organizing the trip Hugh. Come to the geoclub pot-luck dinner - see below.

Geocene 11 is now available for downloading and has 10 articles on a variety of topics, many from recent club trips. For any errors in fact or fiction please contact Hugh (h.grenfell@orcon.net.nz) for them to be corrected.
