Bring your favourite rocks, minerals, fossils and pebbles for the Geoscience Society of New Zealand’s Drs Rock to identify. Challenge them with something puzzling. What's this rock? Where's it from? How did it form? Why is it this colour? Could it be gold? Is it a meteorite?

Come and see rocks that float, rocks that fizz and rocks that are magnetic. Discover the stories of the rocks in and under Dunedin, New Zealand, and Earth's 8th continent Zealandia.

Children under the age of 14 must be accompanied by an adult.
