Child Support Deductions
This guide discusses an employer’s obligation in relation to child support deductions.

Income New Zealand “WINZ” benefit under the Social Security Act 2018, or has applied to the Court for
maintenance order under the Family Proceedings Act 1980.

than PAYE, employers must deduct child support before anything else, such as student loan repayments,
insurances, superannuation and union fees. Child support must be deducted from final pay and holiday
pay on the termination of employment.
It is possible for employers to be asked to make deductions for child support from contractors and
commission agents (non-employees).
