You can apply for child support if your child qualifies, at least 1 parent can be required to pay, and the child lives with 1 carer for at least 35% of the time.
Your child support will end if you, the child or the other parent no longer meet all the requirements.
The requirements on this page are only for voluntary agreements and formula assessments. If you have a private agreement, you and the other parent decide when and how much child support is paid even if you do not meet all these requirements.
Minimum care requirements
To get child support under a formula assessments, your child needs to live with you for at least 35% of the time – that’s about 5 nights a fortnight or 128 nights a year.
You may also be able to get child support if your child is at boarding school and you pay the fees.
There are no minimum care requirements for voluntary assessments.

Paying parent requirements
For a parent to be made liable for (required to pay) child support, they:
- must not be living with the child, or are sharing care of the child with someone else
- must not be in a relationship and living with the person they are paying child support to.
A parent can mean any of the following.
- They are named on the child's birth certificate as a parent.
- They legally adopted the child.
- They were married to the other parent when the child was conceived or born.
- They have acknowledged before a court, or in writing, that they are the child’s parent.
- The Family Court declared them a legal step-parent.
- A court declared them the child’s parent through a paternity order.
They must also be either:
- a New Zealand citizen or ordinarily resident – that is, living here as their main home
- resident in Australia or another country we have a child support agreement with (this only applies to formula assessments).
