Wild storms at sea over the past week combined with high tides to expose sand sausages near St Clair beach and scar other banks.
Dunedin City Council community and recreation services manager Mick Reece said a digger started repairs on Sunday, and it was hoped to have the work finished by the end of the week.
However, high winds have kept Port Otago's dredge, which collects the sand needed for the work, in port for the past few days.
Contractor Doug Hall said 4000cu m of sand was dumped on the beach last month.
He estimated the beach had been built up by about 1.5m in the 11 months since the work started on the beach.
The council's community development committee will consider the issue today, but much of the discussion is expected to be behind closed doors.
Mr Reece said the council needed to find a long-term solution to the problem.
