Traffic management measures have been wrongfully removed from the closed area of the Tapu-Coroglen Road, Thames-Coromandel District Council reports.
The removed measures include large concrete barriers, safety fencing, posts and traffic cones that were installed about 10 kilometres from Tapu after a large slip at the end of January.
The council says the road - which runs across the peninsular - is impassable for the foreseeable future. Properties can be accessed from either the Tapu or Coroglen end, but detours for residents to travel to the other side of the slip are lengthy.
The council says it wants to remind residents that the closure of the road is ongoing and is a matter of public safety.
