A section of Fruitgrowers Rd in Clyde has been closed as a precaution after rocks fell on to it at the weekend.
The road was closed on Saturday afternoon, after rocks, believed to have been loosened by heavy rain, fell from a bank above the road the previous night.
Senior Constable Mike Colligan, of Alexandra, said "quite a few rocks came down overnight".
Some needed two people to shift them.
"I looked up [the bank where the rocks came from] and thought it doesn't look good ... I wasn't happy [with the situation]."
After consultation with Central Otago roading engineer Peter Cuthbertson, the affected section of road was closed until further assessment could be carried out.
The road closure effectively cut off a popular freedom camping area near the Dunstan Arm Rowing Club but Snr Const Colligan said Contact Energy had opened the top of the dam to be used as a road.
"It was the campers' choice to move [or not], but if the dam wasn't able to be opened then they would have had to go," he said.
Mr Cuthbertson said the risk of more rocks falling was "pretty low" but due to the "potential for harm" the road would remain closed until it could be assessed by an engineer early this week.
