"He had a fire extinguisher and he gave it a go but by then the flames were just too big."
He said police cordoned off the road as the thick black smoke drifted across the road.
"The carport was well and truly alight by then too and the [car] windows started popping, I think the firefighters got there just in time before it reached the fuel tank.
"It seemed like quite an old car, about 20 years, there was no way any of us could have put it out."
The Bay View volunteer fire brigade attended the blaze.
A New Zealand Fire Service spokeswoman said yesterday's incident was nothing more than "a little bit of smoke coming from a car" and was "left in the hands of the owner".
