Papakura residents were awoken early this morning to the sounds of explosions, and arose to find a car ablaze in a nearby parking lot.
Corey Hampson woke up about 5am to the sound of "bangs" in Red Hill.
"I thought they were fireworks at first, then I looked outside the window and saw a bit of smoke," he said.
Hampson heard another bang and woke his friend, and they went outside to investigate.
They spotted a car parked across the middle of a parking lot near the dairy, he said.
