A six vehicle crash blocked the Southern Motorway yesterday which was already congested with holiday traffic.
The accident, near the Takinini off-ramp heading south, happened shortly after 12.30pm.
It is not known if anyone has been seriously hurt.
A few minutes earlier two cars crashed at the base of the Auckland Harbour Bridge blocking a single lane.
A police spokesman said that accident had since been cleared.
Traffic had already reportedly been slow both north and south of Auckland as motorists returned home following Christmas and left for their summer holidays.
