Firefighters have extinguished a blaze after a tractor burst into flames in North Dunedin today.

He rushed to get a extinguisher out of his car, but by then the fire was too large and had little effect, he said.

Firefighters arrived quickly and extinguished the flames.

Fire and Emergency New Zealand Dunedin City station officer Martin Hastie said the cause of the fire was being investigated.
