Police have narrowed their search for missing 69-year-old Christchurch woman Adele to a cluster of streets in Burwood and are urging residents there to check their properties.

Adele was last seen on Monday 15 June, leaving Eastgate Mall about 1pm, wearing a black puffer jacket over a red top and blue jeans.

Detective Sergeant Luke Vaughan said police believed Adele was seen in the New Brighton Road and Cresswell Avenue area on the evening of Monday 15 June.

“We are now urging Burwood residents to please check their properties and notify police of anything unusual, especially if you are in the New Brighton Road, Cresswell Avenue, and Gayhurst Road areas,” he said.

“If you have any backyards, sheds, sleepouts, or anything where a person could seek shelter, please take a look.”

Vaughan said anyone with CCTV should review footage from Monday 15 June, particularly cameras facing the street.

He said police and Adele’s family were concerned for her wellbeing.

“Any information, no matter how small, may be the key to finding Adele.”

Anyone who sees Adele is asked to contact police immediately on 111, using the reference number 260618/2259.
