Two multi-vehicle crashes are 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.

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

More to come
