Gregory was found dead at her home in Baroda St, Khandallah, shortly before midnight on January 24. A post-mortem revealed her death was the result of a violent act, police said.
Police searched a Porirua landfill in the following days, saying a person of interest was believed to have disposed of items in the hours after Gregory died.
Detective Senior Sergeant Tim Leitch said at the time the search of specific areas within the landfill could “significantly advance” the inquiry.
Neighbours of Gregory’s described her to RNZ as a keen gardener and a quiet woman who kept to herself.
One neighbour, who did not want to be identified, told RNZ that Gregory, who had gone to school with their aunty, spent a lot of her time gardening.
