Wiri Lava Cave, Nature reserve and lava cave in Wiri, New Zealand
Wiri Lava Cave is a subterranean passage system located beneath Wiri Station Road, created when lava flowed and cooled in an underground network. The cave shows varied passage widths and reveals how volcanic activity shaped the geology beneath Auckland.
The cave formed roughly 20,000 years ago when lava flowed beneath the surface and cooled while remaining molten inside, creating hollow tubes. This process shaped an underground network that preserves evidence of volcanic activity in this region.
The Wiri Lava Cave lies within the territory of Matukutūruru volcano, holding geological significance for understanding Auckland's volcanic field development.
Access to this cave is restricted and requires special permission to help protect its natural state. Potential visitors should check in advance about the rules and requirements for visiting.
Researchers use advanced digital mapping techniques to document the cave system in detail and capture rare lava rock formations inside. These methods help scientists understand and protect the underground network more effectively.
