What is believed to be an unfinished waka has been unearthed in Pūhoi, north of Auckland.

The discovery was made on April 16 during excavation work on the Warkworth motorway project, the Ara Tūhono Pūhoi, near the Ōkahu inlet, north of the Johnstone’s Hill Tunnel on State Highway 1.

“A digger identified a wooden object under the surface of the inlet,” says NZ Transport Agency senior manager project delivery Chris Hunt.

“The mud around the object was carefully removed exposing a large rectangular wooden object that extended across the excavation.”

It’s thought the object is a 10-metre long waka still attached to the trunk of a kauri tree.

Work has ceased in the area of discovery and excavation by the project’s archaeologist’s team and the conservation specialist is underway.

Its age or how it came to be left in an ‘unfinished state’ remains unknown.
