Car Seat Basics

Car seats are complicated even for the most experienced people. You should always read your child's car seat manual and have your installation checked by a restraint technician.

This page contains some basic seat concepts that apply to most child restraints, this however does not cover them all.

What is a car seat?

A car seat or child restraint is a plastic or polystyrene seat, containing metal and fabric parts that is made specifically use in a motor vehicle. There are many types of car seats on the market and each serves a different purpose based on your children's height and weight and age

A car seat is required by law for all children under 5 years of age in New Zealand and 7 years where one is available. Children over the age of 8 are required to use an adult seat belt, and where one is not available, must sit in the rear seat of the car.

Why use a car seat?

According to NHTSA, a rear-facing car seat is 71 percent safer than no restraint at all, and a forward-facing car seat is 54 percent safer than no restraint at all. 
Keeping your baby rear-facing to the limit of the seat is the safest choice. Age is not a factor, as long as the child is kept rear facing for a minimum of 12 months.

A car seat correctly positions an integral harness, or adult belt over your child's body to offer them the safest option when in a car. The safest car seat is one that correctly fits your child, and your car and that is used correctly all the time. This includes using the top tether strap if your restraint comes with one.
Without a car seat your child is not secured within the car and is potentially going to fly from the car, through the windscreen in an accident, this could be life threatening or fatal.

Always use a seat that best suits your child's needs - age, height, weight and maturity. I've not yet met any 2 year old who can sit correctly in a booster seat. Always use your child's car seat until the maximum weight (unless your child is too tall for the seat) has been achieved, before graduating to the next type.

Only use a child restraint that is approved to standards accepted in New Zealand. We accept NZ "S" Mark, Australia's "5 Ticks", and UK ECE 44.03 standards. Seats from America must also display the NZ "S" mark.

Did you know?

That 100% of children under 5 years of age require a child restraint
90% of 6 to 8 year olds require a booster seat as does
50% of 9 to 10 year olds and
10% of children aged 10 to 12 years.

These children still need to use some form of child restraint, this is most likely a booster seat for older children and a harnessed car seat for younger children. This does not mean that children out grow their car seat the day they turn 5. Remember your child is 5 years old until the day of their 6th birthday.

How can I tell?
If my child has outgrown their car seat?
If my child is big enough to use an adult belt?
