The Waste Management truck rolled on the Takanini northbound onramp.
A rubbish truck container has fallen off a truck, blocking an on-ramp leading to Auckland's busy Southern Motorway and leaving debris strewn across the road.
Emergency services are at the scene of the incident, on Takanini's northbound on-ramp.
There are no serious injuries.
Images from a traffic camera show the back of a two-container truck twisted on its side.
The on-ramp is closed and drivers are being asked to use the Hill Rd on-ramp instead.
