Police say the circumstances of a house fire in Hamilton overnight are a cause for concern.
A joint police-fire service investigation is underway today working to establish the cause of a fire in Hamilton overnight that left a Frankton home seriously damaged.

"What started the fire is yet to be established but we can confirm the circumstances around the fire are certainly cause for concern for us," Mr Keall said.
