Due to recent earthquakes, some of the rock has cracked and there is a danger of rock fall. The signal mast structure at the top of Cave Rock has also suffered some damage. The Council has erected signs advising people to keep off the rocks for their safety, and fencing has been erected near the pavement at the base of the rock and on the rock.
The signal station at the top of Cave Rock was used to signal vessels approaching the Sumner bar when the wharf at Ferrymead was used to unload cargo for Christchurch in the nineteenth century.
Repairs to the signal mast structure are hoped to be carried out over the coming weeks.
Recent geotechnical reports indicate that Cave Rock is not in danger of collapse, however until repairs have been completed in the interests of safety people are advised to keep off the rock and not to enter the cave.
