The NZ Transport Agency is advising motorists to expect delays and avoid the Southern Motorway between Papakura and Takanini due to an incident.
All three northbound lanes are blocked after a truck jack-knifed.
Incident response teams are on the scene but it’s not known how long the truck may take to be cleared.
Traffic is being diverted on to the Papakura off ramp.
Motorists should avoid the area if possible or delay their travel.
