The Kaimanawa Wall: A "Pyramid" That Is Rock

A block-like outcrop in New Zealand's central North Island was promoted in the 1990s as the remains of a pre-Māori pyramid. Geologists showed it is naturally jointed ignimbrite, volcanic rock that cracks into regular blocks.

Sources Te Ara – the Encyclopedia of New Zealand, 'The Kaimanawa wall' (Manatū Taonga); Department of Conservation and GNS Science statements; Wikipedia, 'Kaimanawa wall'

In 1996 a New Zealand magazine and then fringe authors began promoting a set of large, squared blocks in the bush south of Lake Taupō as the Kaimanawa wall: the remains of a pyramid or structure built before Māori arrived, perhaps by a vanished white or Celtic people.

What it is

Geologists from the Institute of Geological and Nuclear Sciences examined it. The blocks are ignimbrite, a rock formed from hot volcanic ash that settled and welded. As ignimbrite cools it often cracks along regular joints, producing surprisingly square blocks. This outcrop belongs to a sheet roughly 330,000 years old that runs underground beyond the “wall.”

Why it matters

Te Ara, the government’s encyclopedia, notes the story’s connection to a long line of claims that someone other than Māori settled New Zealand first, claims that have been used to belittle Māori history. The rocks are interesting for their geology, not for a lost race.

Ledger status

Marked hoax for the structure claim. Map position is region level within a conservation area.
