Safe Kids is calling for helmets to be compulsory for children riding scooters after an increase in the number of injuries.
Accident Compensation Corporation figures show the number of scooter-related injuries for children up to age 14, rose from 1047 in 2008 to 7553 last year.
Safe Kids says requiring children to wear helmets reduces the risk of serious head injuries.
Director Ann Weaver said the group will be talking to decision makers about the importance of the issue and why a law change is necessary.
From August the group will start a campaign in schools promoting road safety, urging them to adopt a ''no helmet, no scooter rule''.
