A truck driver is having a crap day after a vehicle used for emptying out portaloos overturned in Pukekohe - spilling human waste on the road.

The truck - which contains a tank holding an estimated 1000 litres of human waste - overturned on Gun Club Rd about 9.15am.

The driver suffered a bruise to her leg but was otherwise uninjured.

Fire and Emergency northern communications shift manager Megan Ruru said the truck had leaked a small amount of effluent on to the road.


The container was still leaking, Ruru said.

A tow truck righted the truck and firefighters hosed down the road.
