An agency review finds urgent change is needed at Oranga Tamariki -- as it highlights ill-trained managers and alleged bullying

Staff say there aren't enough beds, there's little vision, and processes are slow, confusing and bureaucratic.

Whanau Ora chair and child welfare advocate Merepeka Raukawa Tait isn't surprised at the findings.

She says it's not safe for the children -- and if she was a parent, she'd run a mile before she had anything to do with Oranga Tamariki.

The review uncovered 46 complaints ranging from inappropriate language and supplying contraband -- to alleged physical and sexual assaults.

Twenty-eight were referred to Police.
