The Chief Ombudsman says we can't yet be confident Oranga Tamariki will keep kids safe following the release of a new report.

This report revealed Oranga Tamariki failed to investigate an abuse case involving four children, despite nine separate reports of mistreatment by their mother's partner.

Peter Boshier says Oranga Tamariki was also given photographic evidence related to these incidents - and they should have carried out a proper in-depth investigation, at the very least. 

"I had hoped that after I did my report on the death of Malachi Subecz two years ago - and the assurances were given by Oranga Tamariki that there would be dramatic change. And yet, this has happened."
