Why the Waitomo Glowworm Caves are unique


The Waitomo Glowworm Caves are over 30 million years old created by the incredible forces of nature and the earth’s geological and volcanic activity.

The cave are formed in limestone dating back to when New Zealand, and the Waitomo region sat beneath the ocean. Because of this time spent under water, a huge amount of corals, seashells and small organisms have layered then fossilized creating the limestone in the caves. In some places, this limestone is over 200m thick.

The two tectonic plates – Pacific and Indo-Australian – upon which New Zealand sits begun crashing into each other forcing our country to rise out of the ocean. The hardened limestone has bent and buckled under enormous pressure. The process of uplift created cracks which has in turn allowed water to flow into the rock, slowly dissolving the and creating what we now now as the Waitomo Glowworm Caves. ​
