Ms Webster said the most common issues the three agencies wanted to address included car seats that don't fit in the car correctly, tether straps not being used, expired car seats and car seats that children have outgrown.
When installed correctly, child car restraints reduce the risk of death for infants by up to 70 per cent, for toddlers by up to 54 per cent, and the need for hospitalisation for children four years and under by up to 69 per cent.
"It's really interesting when we talk to school aged children and ask them who in their family doesn't wear a seatbelt, their response is often 'mum or dad' "
Police checkpoints throughout the district are planned over coming months.
