Returning holidaymakers heading home are encountering traffic delays in Auckland and Wellington and the Waikato regions.

A crash on the Auckland Harbour Bridge means it is down to two northbound lanes at a crash site near the centre of the bridge.

NZTA said: “Expect delays northbound at this time. Congestion is present northbound between SH1/SH16 Spaghetti Jct and the bridge itself.”

Two multi-vehicle crashes are also slowing traffic in Waikato as many Kiwi holidaymakers return home this weekend.

Police said there are no serious injuries from either crash but they have both affected traffic and have advised motorists to expect delays.

One crash involved two cars at the intersection of State Highway 1 and Maungatautari Road and was reported to police at 11.35am.

The other two-car crash was at the intersection of SH29 and Totman Rd and was reported to police at 12.40pm.

In Wellington region, SH1 southbound was also facing delays.

NZTA said SH1 was down to one southbound lane south of the Kapiti Rd on-ramp, following a trailer roll.

“Expect delays southbound through this route as emergency services and contractors attend.”

It comes as Kiwi holidaymakers return home ahead of the usual work schedule resuming for many on Monday.
