Wiri lava cave is Auckland's longest known lava cave at around 290 metres.[1][2] It is part of Matukutūruru (Wiri Mountain) volcano, in the Auckland volcanic field. Because it features rare lava stalactites the cave has garnered international renown. The cave entrance is locked and entry is by permit only.
The cave is up to 7.6 by 3.6 m (25 by 12 ft), down to 1.1 by 0.2 m (3 ft 7.3 in by 7.9 in), and is located about 4 m (13 ft) below Wiri Station Rd.[3]
