State Highway 25 between Hikuai and Opoutere remains closed this morning following further collapse of the underslip overnight.
Waka Kotahi NZ Transport Agency said convoys were allowed through for a short window his morning but the highway needed to re-close once the convoys were cleared to allow urgent work to continue.
Thames Coromandel Council said further movement occurred overnight which meant the road would be fully closed until this afternoon while further stabilisation work and widening took place.
Civil Defence Controller Garry Towler urged everyone intending to travel through the area to delay or make alternate arrangements today.
