Waitomo Caves

The Waitomo Caves are a village and cave system forming a major tourist attraction in the northern King Country region of the North Island of New Zealand, 12 kilometres northwest of Te Kuiti. The community of Waitomo Caves itself is very small, though the village has many temporary service workers living there as well. The word Waitomo comes from the Māori language wai meaning water and tomo meaning a doline or sinkhole; it can thus be translated to be water passing through a hole. These Caves are believed to be over two million years old.^{[citation needed]}
