Drivers have been warned to look out for numerous road works and hazards in Tauranga.
The annual AIMS Games, which sees thousands of 11-13 year olds and their guardians descend on Tauranga, begins on Sunday and would continue through until Friday September 9.

Tauranga City Council would provide a free park and ride service.
