Tell us when your circumstances change

It's important to tell us when your circumstances change. Some changes will affect the child support formula assessment, keeping us up-to-date means we can assess you correctly.

You need to tell us if:

  • you change your address or contact details
  • you're going overseas
  • you start to provide care for your child (or children) for 28% (103 nights) or more of the time
  • there is a change to the level of care you provide for your child (or children)
  • your income changes (parents only)
  • you start or stop receiving a benefit from Work and Income
  • you start living with the person you pay child support to, or receive child support from
  • any of your children start working full time (30 hours or more), receiving a benefit or student allowance, or starting living with a person in a marriage, civil union or de facto relationship
  • any of your children leave your care
  • you change your bank accounts
  • any child you pay or receive child support for is no longer a New Zealand citizen or ordinarily resident in New Zealand
  • you have any other changes which may affect your child support calculation.
