Traffic has resumed to normal after two crashes that took place within five minutes of each other on either side of the State Highway 1 near Rolleston.

The incidents had caused serious traffic delays.

A two-car crash near Berketts Road in the north had resulted in bumper-to-bumper traffic and motorists were being advised to take a detour via Jones Road.

There was also a significant bottle neck near the site of a second crash on the south side of Rolleston at the intersection near Walkers Rd.


None of those involved were injured, said St Johns Control Centre Team Manager Alan McKay.

Drivers should avoid State Highway 1 if possible, NZTA had advised.
