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.

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
Zoologist Daniel Thomas gave an amazing encyclopaedic account of NZ fossil penguin genealogy at the April meeting and Hugh Grenfell gave us another 10 mins on Great Mercury Island geology. Many thanks to both speakers. In early May, 21 members (8 cars) completed a six day tour of the geohighlights of Poverty Bay and East Cape. Hipoints were the double Mangatu and Tarndale slips that have obliterated the road Geoclubbers drove along in 1996; Sponge Bay fossil forest and seafloor that was diapirically thrust up 15 days after the Napier earthquake; amazing diatomite books at Ormond; Te Puia springs active and fossil sinter; East Cape cold seep concretionary doughnuts; climbing 775 steps up to East Cape lighthouse; Te Araroa manuka oil distillary (and café); rich fossil pickings at Te Araroa (late Miocene), Oweka Valley (Pliocene) and Te Piki (mid Pleistocene). Many thanks to our guest leaders Phil Moore and Mike Mardin, leader Bruce, and organisers Helen, and Christine.
