Several hundred litres of diesel spilled on Auckland's Ponsonby Rd this morning, causing havoc for motorists.
Emergency services were contacted about 8.10am after a car slid off the road and ended up on the grass at Western Park off Ponsonby Rd.
Ponsonby Fire Station officer Shane Olsen said it appeared a truck had leaked fuel as it drove up Williamson Ave, onto Ponsonby Rd and then down Hopetoun St.
The truck had not been located and Mr Olsen suspected its driver had not been aware of the leak.
He estimated several hundred litres of diesel had spilt.
