A stark picture of the consequences of Oranga Tamariki's system not helping young Maori enough

An Independent Children's Monitor report shows tamariki and rangatahi Maori 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 Maori adults involved in the system as children - are nine times more likely to have lived in emergency housing.

He says they're half as likely to be employed, twice as likely to be victims of crime, five times more likely to use mental health services - and 10 in a thousand will take their lives by the time they're 30.
