Child Seatbelt Safety Restraint Accessories & Products

Seatbelt Sales in Christchurch supplies a range of child safety products designed to ensure young passengers are correctly and securely restrained on every journey, from short school runs to long road trips.


New Zealand law requires that children be restrained in an approved child restraint or seatbelt appropriate for their age, height and weight. The specific requirements vary depending on the child's age, but the underlying principle is consistent: children must be restrained in a way that is appropriate for their size and development and that provides meaningful protection in the event of a collision.


The consequences of inadequate child restraint are severe. Children are significantly more vulnerable than adults in vehicle collisions because their skeletal and muscular systems are still developing, and a standard adult seatbelt is simply not designed to protect a small child effectively on its own. The right restraint system, correctly fitted and used every time, dramatically reduces the risk of serious injury or death.


Seatbelt Sales has been helping New Zealand families travel safely for over 37 years. Our range of child safety products is selected to address the most common needs, including vehicles where standard restraint systems are insufficient, situations requiring extended or adjusted belt geometry, and installations where anchor points need to be added or reinforced.

Child Safety Products We Supply

Child Harnesses

We supply child harnesses designed to securely restrain children in vehicles where standard seatbelts are not appropriate or available. Child harnesses provide multi-point restraint and distribute crash forces across a larger area of the child's body than a standard belt alone. They are particularly useful for children with special needs, children travelling in vehicles with non-standard seating configurations, and situations where a conventional child restraint seat is not practical.

Extension Straps

Seatbelt extension straps increase the length of an existing seatbelt, providing a more comfortable and effective fit for larger passengers, pregnant travellers, or vehicles where the standard belt length is insufficient to accommodate a child restraint correctly. Our extension straps are designed to maintain the structural integrity and locking performance of the original seatbelt, ensuring the extension does not compromise the belt's safety function.

Anchor Points

Properly installed anchor points are essential for securing child restraint seats in vehicles. A child restraint that is not anchored to the correct structural point in the vehicle will not perform correctly in a collision, regardless of how good the restraint itself is. We supply anchor point hardware, including bolts, spacers and reinforcement plates, to ensure child restraints are fitted to the correct structural mounting points in the vehicle body.

Fitting Advice

Correct installation of child restraint products is critical. A poorly fitted harness or incorrectly anchored child seat can fail to provide adequate protection in a collision, regardless of the quality of the product itself. New Zealand has specific standards for child restraint installation, and we encourage all customers to ensure their products are fitted in accordance with those standards.
