Helicopter used on State Highway 25A slip


A helicopter has been used to remove loose rock and dirt from the slip on State Highway 25A this afternoon.

Slip on State Highway 25A

The approximately 2000m3 sized slip came down Sunday night and is currently blocking the road.

The NZ Transport Agency is advising the highway will remain closed tonight as it is not safe for road users. It may open to one lane late tomorrow but intermittent closures will still be needed.

The agency’s Regional Transport System Manager, Karen Boyt says the helicopter was used to encourage any loose material to fall.

“Today our engineers have confirmed the slip is still moving and creating a safety risk to workers and the public.

“The sluicing involved a helicopter dropping around 1000 litres of water on the slope to remove any debris that was close to falling.

“Once the slip is stabilised and the next phase of the plan is put in place to clear the road we will have a better indication of when one lane might open, but at the moment we expect that might be late tomorrow.

“The public and worker safety is paramount and needs to be considered before a decision is made,” Ms Boyt says.
