A Port Chalmers boat shed has been broken into and vandalised five times over the past month.
The boat shed in Sir John Thorn Dr is owned by the Dunedin City Council and leased to Training Ship Nimrod, a youth group for local teenagers.
TS Nimrod unit support committee chairman Jonny Goldsmith said the building had been broken into about five times since late November.
The shed needed work, but the group was actively working towards repairing it.
The vandalism was setting back that process.
