An overhaul of child-support payments will reduce the cost for part-time parents who spend just 28 per cent of the time with their children - two nights a week.
Revenue Minister Peter Dunne, who announced the changes, said they would recognise parents as "shared carers" of children if they had the child for 28 per cent of the nights down from 40 and would give greater consideration of both parents' incomes when determining payments.
Other proposed changes include money being deducted automatically from parents' pay packets and relaxing penalties for non-payment.
Wellington father and truck driver Gareth Young said any new system would benefit children and reduce the need for Family Court bickering.
He said his estranged wife was "going through the courts and racking up debt", which would not be taken into account in calculations for his child support for his kindergarten-aged son, which was currently set at $100 a week.
