NZ Transport Agency Waka Kotahi (NZTA) is advising road users that State Highway 1 is closed through the Mangamuka Gorge due to a large slip this afternoon.

Those who need to travel can detour via State Highway 10.

Contractors are on-site assessing the slip and the stability of the slip site. With heavy rain forecast to continue for the next several hours and the possibility of further slips, the highway will remain closed overnight to ensure the safety of road users.

NZTA will provide updates as further information is available.

Road users can check for the latest updates on the NZTA Journey Planner.

As heavy rain continues to affect the region, people are asked to delay unnecessary travel where possible and, if they must travel, to take extra care.

Motorists should slow down and maintain a greater following distance between their vehicle and the one in front. Be aware of branches and other debris they may not be able to see under the surface of flood waters.

We also ask that people be mindful of contractors who could be out clearing hazards off the road, and drive slowly through work sites.
