Traffic heading north over Auckland's Harbour Bridge is gridlocked back to spaghetti junction after a breakdown in a middle lane.
Vehicles are gridlocked for several kilometres on SH1 while they wait for a vehicle to be shifted from lane two after it encountered engine problems partway over the bridge.
The New Zealand Transport Agency warned motorists to expect delays until the lane is cleared.
Southbound lanes into the city are flowing freely at this stage.
