Key points about car seats
- properly using a car seat is one of the most important things you can do to keep your baby or child safe
- New Zealand law says all tamariki in vehicles must be correctly secured in an approved car seat (restraint) until their 7th birthday
- use a car seat that is made for your child's weight and height.
- to be safest, tamariki need to be in booster seats until they are 148cm tall - this is usually when they are somewhere between 10 and 12 years old
- keep your baby in a rear-facing car seat until they are at least 2 years old
Why car seats are important
Child car seats, booster seats and safety belts can prevent injuries and save your child's life when installed and used properly.
It is important you use a car seat that is made for your child's weight and height and carefully follow the instructions to fit it to your vehicle.
Generally, it's best to put your baby in a rear-facing car seat for as long as possible, or until they are 2 or older. Once they have outgrown this, they can go into a forward-facing one.
It's always safest for car seats to be placed on the back seat. This is because during a crash, a front seat air bag goes off at a high speed and can be dangerous to your child.

How to tell if your child still needs a car restraint or booster seat
Tamariki must use a booster seat until they are 148cm tall - for most tamariki, that's somewhere between 10 and 12 years of age.
Use Safekids' 5 step test if you're unsure if your child is ready to move out of the booster seat.
If you answer 'no' to any of these questions, your child needs to be in a child restraint or booster seat.
- Does your child sit all the way back against the vehicle seat?
- Do your child’s knees bend comfortably at the edge of the vehicle seat?
- Does the belt cross the shoulder between the neck and the arm?
- Is the lap belt as low as possible, touching the thighs?
- Can your child stay seated like this for the whole trip?
