  • 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.

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?


Geophysicist David Robertson astounded all those present at our March meeting with the surprises he had turned up using aeromagnetic mapping over the South Auckland region, including the recognition of a whole buried chain of small volcanoes. At the end of March, fifteen members braved the pouring rain in the early morning to enjoy a sunny field trip examining the varied Pleistocene rocks of Wattle and Big Bays at the north end of Awhitu Peninsula.
This newsletter contains the first invitation to join for a week us on Norfolk Island in Nov. This invite is earlier than usual so members can make sure they get in early to book and get good prices on their air fares as there is only one flight per week from Auck to Norfolk. Numbers may need to be limited so book early to make sure you get on the trip.

Geocene 12 is now available. Download from It contains articles by members on some of our recent trips to Rangitoto, One Tree Hill, Waitomokia, Mt Cook and the upcoming trip to Helvetia Volcano
