EARLIER:
Geotechnical engineers assessed the cliff face on Tuesday morning.
“The bench at the foot of the slip was cleared [Monday] night and overnight rain hasn’t brought down more material,” NZTA said.
“Work to remove remaining debris is underway today with two radio-connected spotters observing the slip face for safety.
“The road cannot be reopened until it’s deemed safe to do so.”
The detour for eastbound traffic is right on to Waiotahi Valley Back Rd, Verrall Rd and left on to Paerata Ridge Rd before rejoining SH2.
Westbound traffic in reverse.
Minor injuries
Three vehicles – a ute and two cars were struck by the slip – police said on Monday.
A Hato Hone St John spokeswoman said one person in a minor condition was assessed and treated.
One ambulance, two rapid response units and one operations manager were sent to the scene.
The slip was covering both lanes.
The road remained closed overnight Monday due to concerns about incoming weather.
The detour was not suitable for heavy vehicles.
