Police have been blitzing schools at bell time to make sure parents are prepared for carseat law changes.
From November 1, children will have to be in an approved car restraint up to their seventh birthday. At present, the law covers children up to 5. Children from 7 to 8 will need to be in a carseat if one is available.
Waitemata police have had checkpoints at four schools and stopped 128 cars to check carseats and make sure parents are prepared for the changes.
Beth Bates of Waitemata Police said around 10 per cent of drivers stopped had an incorrect car restraint or had it incorrectly fitted.
"The stops were purely educational and police were making sure parents knew what they needed to do," she said.
