A man is helping police with the investigation into the disappearance of a North Shore woman.
A forensic examination is under way at a property in Torbay, 11 days after Bin "Cissy'' Chen, 44, failed to return home from her regular evening walk.
She left her Torbay home about 5.30pm on Monday last week, and when she did not return home her distressed partner raised the alarm.
Extensive land and air police searches of Long Bay reserve and the surrounding area have failed to turn up any sign of her.
There have been no public sightings of her since she went missing, confirmed police.
