A group of parents at the centre of a review into the anti-smacking law say they reject the findings of the report.

Television psychologist Nigel Latta, Police Commissioner Howard Broad and Social Development Ministry chief executive Peter Hughes carried out the three-month review and concluded that none of the cases highlighted by pro-smacking lobby Family First stacked up.

Family First had used them as evidence that the repeal of Section 59 of the Crimes Act, effectively banning smacking for the purposes of correction, had failed.
