The NZ Transport Agency is advising that State Highway 4 between Raetihi and the intersection with Fields Track is closed until further notice.
An underslip occurred over the weekend and, in the days since, a crack in the road has significantly worsened and the road has had to be closed.
The Transport Agency has commissioned a geotechnical investigation to determine the exact cause of the slip and its severity, and to help identify what repair work needs to be done. The investigation will begin today. Once it is complete, the Transport Agency will be able to provide a further update.
Until then, the road will remain closed. The detour route for light vehicles is via State Highway 1 and Fields Track. Heavy vehicles are advised to use State Highway 1 and State Highway 49.
Plan ahead for a safe, enjoyable journey. Keep up to date with:
