The Minister for Children has called for an investigation into the treatment of a young child by Oranga Tamariki.

RNZ revealed this morning that a child spent more than nine weeks in a Waikato hospital because the agency failed to find them a suitable placement.

In documents posted online by the cyber hackers who attacked the Waikato DHB, staff said the child did not require hospital admission for any medical reason and was not unwell.

Māni Dunlop spoke to social worker and former state care survivor, Paora Crawford-Moyle and advocate Julia Whaipooti.
