The August 10 house fire was described by the family as the most horrific day of their lives.
A dehumidifier is believed to have caught fire in the middle of the night.
The couple were woken by the flames and called emergency services but Joy, a grandmother and mother of three, did not make it out.
On Monday, 22-year-old local man Luke McMahon, a bricklayer, appeared in the Waitakere District Court after allegations he was spotted at the property with a tow truck, allegedly trying to remove two cars.
A neighbour called police.
McMahon faces four charges, including one of deceptively obtaining control over property, two charges of dishonestly taking two cars, and being in an enclosed yard.
He was remanded on bail without plea and will reappear in court in January.
It's one of several incidents across the country where people have allegedly stolen from the sick, dying or vulnerable. In October a 24-year-old man was arrested and charged with robbing Waihi man Henry Pere of his wallet as Pere suffered a fatal aneurysm in public.
In November a woman injured in a serious car accident was allegedly robbed by a man who stole her wallet and phone from inside the car.
