Heavy traffic is expected to slow things down in Auckland this week as thousands of youngsters return to school.
Many primary school-aged children started back yesterday, while more students - including high school pupils - will head back on various days this week and next.
Auckland Transport said yesterday did not bring too much congestion but motorists were being warned that would change in the coming days.
Spokeswoman Sharon Hunter said the School Travel Plan programme was one way Auckland Transport was working to reduce cars on the road.
Schools were encouraged to take on the programme, which has students participating in the Walking School Buses initiative or cycling to school rather than being dropped off in a car.
