New research paints a stark picture of the consequences of Oranga Tamariki's system not helping young Māori enough.

An Independent Children's Monitor report shows tamariki and rangatahi Māori are over-represented - and being let down.

They make up two-thirds of those in care and more than three-quarters in youth justice custody.

Monitor Chief Executive Arran Jones says young Māori adults involved in the system as children are nine times more likely to have lived in emergency housing.

"This report makes the case for that investment approach - putting the right people in place at the earliest time."
