In 1996 claims spread that a block-like formation in Kaimanawa Forest Park, south of Lake Taupō, was a wall built by a pre-Māori civilisation.

The account
The story, promoted in books and newspapers, became part of 'lost race' theories that deny Māori were New Zealand's first settlers.
The sceptical view
Geologists showed it is a naturally jointed outcrop of ignimbrite, a volcanic rock that cracks into blocks as it cools; the 'pre-Māori' narrative is rejected by archaeologists and is seen as harmful.
