Senior Sergeant Craig Dinnissen, of Dunedin, said the burglary targeted a range of items including Powerade, chips and eight ice creams from the Lifeline Convenience Store in King Edward St.
A 17-year-old man on bail for other offending was arrested and faces charges of burglary.
Two boys, aged 15 and 13, were found hiding in the shop by a police dog team.
The boys would be referred to Youth Aid.
