Northland police are investigating the unexplained death of a young child from nine years ago.
Four-year-old Alestra Kepa-Hati died in Kaikohe in October 2015.
Detective Senior Sergeant Christian Fouhy says at the time she was living with caregivers in the rural town.
Alestra reportedly suffered a minor seizure, fell and hit her head.
When her caregivers went to check on her after she went to bed she was limp.
