Authorities are concerned for the welfare of a 10-month-old baby after his mother stopped contact with Child, Youth and Family earlier this month.
Police were trying to find 20-year-old Nikki Cribb and her son Bailey, who are believed to have travelled out of the Auckland area.
Ms Cribb had not been in contact with CYFs since May 7, police spokeswoman Beth Bates said.
Police and CYFS had concerns for the welfare of Bailey and anyone who had seen Ms Cribb was asked to contact those agencies, she said.
The pair might be in the Hamilton or Tokoroa areas.
Information could also be given anonymously to the organisation Crimestoppers on 0800 555 111.
