A large section of a back road between Wairoa and Gisborne on the East Coast has collapsed, police say.
In a statement, police said a section of Tiniroto Road, between Rockhill Road and Parikanapa Road, was impassable.
Signage was being put up to warn drivers.
"Anyone needing to travel between Wairoa and Gisborne is advised they will need to use State Highway 2."
The area has previously seen damage from flood events such as Cyclone Gabrielle.
A Bailey bridge was installed to help reconnect communities.
Following the cyclone, a large slip near Tiniroto Road threatened a home.
