Two fires at the same property within a few days are being treated as suspicious.
Ruakaka firefighters were called to a house fire in Princes Rd, Ruakaka, on Monday night - and were called back to the same property on Thursday at 8.21pm, after residents found a caravan on fire.
Ruakaka Fire Station Officer Jeff D'Ath said both fires were discovered early so there was only minor damage.
Whangarei police spokeswoman Sarah Kennett said the culprits burned a rear panel on the caravan and on Monday night a small fire was lit on a foundation pile on the side of the house.
"Both fires were relatively small but are of concern considering the proximity to the home owner," she said.
