Child Youth and Family is to review how it handled a case where five children were so badly neglected they had to eat rotten food.
"CYF received reports of concern in relation to the family prior to 2015 and we worked with the family on the presenting issues alongside other agencies," CYF Auckland regional director Sharon Thom said in a written statement.
"In 2015 when the children were found neglected home alone, they immediately came into CYF care and the mother was charged."
Now the kids "are thriving with whanau caregivers", Thom said.
Their mother, Tala Pita, 33, of Manurewa, was today sentenced at the Manukau District Court to six months community detention and 18 months intensive supervision for five charges of wilful neglect.
