New figures are laying bare the failings of Oranga Tamariki.

The Independent Children's Monitor has found the agency is placing a third of children into care, before completing caregiver assessments.

Social workers are only making 29 percent of their planned visits to children in care.

Executive Director Arran Jones told Mike Hosking these children come into care because their home life is unstable.

He says they've been removed from their family to keep them safe, so important these standards are met, so they can have a better quality of life.
