The Dunedin City Council admits someone could have been injured by a new sinkhole at the Esplanade in the suburb of St Clair. The hole is 3 metres long and 50cm deep.
Council contractors have been shifting rocks below the popular seaside walkway in search of the source of the new hole which developed yesterday.
Since June last year, the council has spent $680,000 fixing and shoring up the seawall after deep sink holes closed it for 10 days. It was alerted to the new hole last night and has roped off the area.
Dunedin council's roading maintenance engineer Peter Standring said that he's aware of the danger.
"There might have been a void under there and someone might have stepped into it. It is a hazard, it is a concern. We do keep an eye on the actual sand levels, we'll just have to keep a bit of a closer eye on the actual pavers as well."
Mr Standring said the hole is was not affecting the structural integrity of the seawall. He said the
council still needs to work out a long-term solution for the wall, but maintenance would always be needed.
