Calls for a review of New Zealand's child support system, which is being described by some as broken..

Figures released under the Official Information Act reveal just 0.05 percent, or 36 of 66-thousand New Zealanders in breach of child support responsibilities have been referred to court, in 12 months.

Family law barrister Sharon Chandra says the general tenor of feedback she gets, is that the system is broken.

She says that's not solely because of a lack of enforcement action, but also because of the assessed amounts that IRD direct parents to pay.

The total that New Zealanders are currently in arrears by is 663-million dollars.
