North Canterbury woman Anna James-Revell is still missing, five days after family reported her disappearance.
Detective Inspector Darryl Sweeney said police were still concerned for her wellbeing and had today been going door-to-door in the area where she was last seen.
James-Revell, from Cust, was last seen on Oxford Rd at 7.55pm on Monday.
At the time, she was wearing a black hoodie and old three quarter-length black tights with holes in them.
Sweeney said there was nothing to suggest anything sinister had happened to her but police were urging property owners to check buildings for any sign of James-Revell.
