New Zealand child welfare head resigns after furore over Maori family separations

Grainne Moss had been under pressure after reports into systemic bias at Oranga Tamariki

The embattled chief executive of Oranga Tamariki has stepped down, saying the focus of the story has become about her, rather than the well-being of New Zealand's most vulnerable children.

Grainne Moss's resignation follows growing concern about the uplift of Mori babies, and the high number of Mori children in care - they account for 65% of kids in state care though Mori comprise just 16.5% of the country's population.
