A surveillance camera has been set up at St Gerard's School where bags of dog poo have been dumped almost daily, for the past year.
Central Otago District Council regulatory services manager Lee Webster and the town's dog control team has been working with the school this week, on ways to monitor the situation to either deter the culprit, or catch them in the act.
The school principal, Trina Eastwood, was grateful for the council's support, in particular, the dog control team, which had set up a camera in the targeted area.
Dog control staff have monitored the area each day since.
Two bags of dog poo were found on the school grounds the first morning and none the second.
As of yesterday, the culprit had still not been caught.
If caught, they could face a fine of $300 and lessons on how to be a responsible dog owner.
Mr Webster said the situation was "totally unacceptable".
