There has been no sign of an accountant missing from the North Shore for 10 days, police say.

Detectives are continuing to interview family and associates of Bin "Cissy" Chen and her partner to try and establish what has happened to her.

Chen, a 44-year-old accountant, went for a walk from her Torbay home about 5.30pm on Monday November 5 and never returned.

Her partner told police that she often went for walks on Long Bay beach but her normal route was not dangerous.

Despite police land, sea and air searches and a public appeal last week, no trace of Chen has been found. There have been no public sightings.

Detective Senior Sergeant Megan Goldie said yesterday that police were still working on the case, with a lot of people still to talk to.

"If we get new information we will start the physical search again. But at this stage we have run out of places to look," Goldie said.

Chen is described as a  44-year-old Chinese woman of medium build and 1.56m tall. She was last seen wearing dark trousers - possibly blue jeans - and a white fleece top.

Meanwhile, Rotorua police have growing concerns for the safety of a woman who also was last seen 10 days ago.

Michelle Hoffmann-Tamm, 51, left her home in Phillip St, Rotorua, about 6pm on November 7 on a red mountainbike, telling her partner she was going to visit friends. She never arrived. 

She is described as European, about 5ft (1.5m) tall, of medium build with short dark hair.
