The man who died following a suspicious house and car fire in Northland has been named as 61-year-old Hoani Reupena-Tuoro.
The Whangārei man was also known to friends and whānau as John Reuben.
In a statement, Detective Inspector Al Symonds said the police investigation into the fire at the Tikipunga property was ongoing as they "support the whānau, dealing with the loss of their loved one in such tragic circumstances".
Efforts were made by first responders to save Reupena-Tuoro after Fire and Emergency NZ found him but he died at the scene.
Symonds said the exact circumstances surrounding the fire had yet to be determined.
"We wish to thank the public for the information and assistance provided so far, however we would still like to hear from anyone who was in the area or who may have information in relation to this incident."
