The victim was revealed to be 88-year-old woman Thelma Durant, her family confirmed to Stuff yesterday evening.
The Herald understood she was the sole occupant of the house. Her body was found by police after the initial fire in the early hours of Tuesday and was removed later that afternoon.
The woman had a son, but neighbours said she largely kept to herself.
Fire and Emergency arrived when the initial blaze sparked shortly after 3.30am, crews engaged in active firefighting to extinguish the blaze.
Fire crews had left the scene by 7am; however, the blaze reignited inside the home half an hour later, with white smoke billowing out of the property and filling the street.
Appearing as fog, houses to the right of the home were engulfed in the thick smoke as the wind blew it through.
Several neighbours across from the property stood outside their homes, some wearing dressing gowns, to witness a repeat of the early morning’s action.
Detective Wells said anyone who might have relevant information to help inquiries are urged to call police on 105 and quote the file number 230222/9020.
