A man has been killed after two cars crashed head-on in South Waikato.
State Highway 1 in Putaruru remains closed after the accident, which happened at 6pm, but police said it would reopen by 11pm.
The male driver of the second car received moderate injuries and was taken to hospital.
And a trailer has overturned on Lichfield Road, one of the roads - including Main Street and Princess Street - that traffic was being diverted to.
Police said Lichfield Road was down to one lane, making it impassible for trucks, and would stay that way for up to an hour.
Police have advised truck drivers to take a break.
The Serious Crash Unit is investigating.
