Waka Kotahi New Zealand Transport Agency is giving the latest update on the State Highway 25A slip in the Coromandel.

"Our crews are carving a temporary path above the road to allow geotechnical engineers to gather soil samples from above the missing section of road," says a Facebook post by the agency.

"This work will help us determine the best way to restore the state highway

"We're currently looking at three options: Building a bridge to replace the lost section of road, building a road around the slip to bypass the lost section of road, or building a retaining wall and then rebuilding the road."

"We need good weather to do this work—we're hoping the tracks needed for access can be completed within two weeks."
