Fire crews attended a ''string'' of suspicious fires in South Dunedin on Saturday morning, St Kilda Senior Station Officer Ben Pitelen said.
''We don't know if they were related. They quite likely were.''
A Fire Service southern communications spokesman said crews from St Kilda and Dunedin stations were called to Oxford St about 1.50am on Saturday to a van fire and a fire on a logging truck wheel.
A dry powder fire extinguisher was used to put out the fires, he said.
An hour later, the St Kilda crew were called to a fence fire in Grove St.
Southern District Command Centre deployment co-ordinator Senior Sergeant Craig Brown said police investigated the fire on Saturday. Inquires were continuing.
The suspicious fires in Grove St damaged a fence in front of a house and a letterbox of a neighbouring house, Snr Sgt Brown said.
