The Transport Agency said heavy rain over the weekend was likely to be the reason for the slip, which brought down about 10,000 cubic metres of material, including large boulders.
An Agency Manager Ross I'Anson said it demonstrated the Gorge's current instability.
While State Highway 3 through the Gorge is closed, motorists have been diverted to the Saddle Road and the Pahiatua Track to get between Manawatu and Hawke's Bay.
The Agency is upgrading both to cope with the increased traffic.
