Children's Commissioner Judge Andrew Becroft says he will not use the English name of the newly announced Ministry for Vulnerable Children and hopes the name will "wither on the vine".
Becroft says he will only use the Maori name of the new ministry, Oranga Tamariki, which means the health and wellbeing of children.
He says the Maori name is "aspirational" and positive, whereas the English name is negative, emphasising children's vulnerability rather than their wellbeing.
Becroft has argued against the English name since he became Children's Commissioner last month, but the name was confirmed today by Social Development Minister Anne Tolley who will also become the first Minister for Vulnerable Children.
"I won't call it anything other than Oranga Tamariki, and that is a challenge for all in the field," Becroft said.
