The Waitaki district council said a new section of the limestone shelf under Beach Road, between the towns of Kakanui and Oamaru, has broken away this week and is back to only one metre from the road.

In May an 80 metre long slip cut into the cliff edge below Beach Road and the road was subsequently reduced to one lane.

The council was investigating buying farmland to shift the road at least 20 metres inland.

Council roading manager Michael Voss said the slip was a safety concern and a fence was being put up on the road's shoulder to alert the public.

A geotechnical engineer was assessing the cliff face's stability.
