An empty shell is all that is left of a car after it burst into flames in Mount Maunganui.

Firefighters were called to the car fire on Grenada Street at 11pm, and found the car fully alight.

At the time of the blaze, Mount Maunganui firefighters were unable to determine the cause of the fire, says Northern Fire Service communications manager Paul Radden.

'Police are notified of any car fire,” says Paul. 'So they were notified.”

The cause of the fire is under investigation.
