The body of a missing Auckland woman may be found in a secluded area such as a green belt or rural bush reserve, police say.
It is 22 days since Bin Chen, known as Cissy, was last seen at her Torbay home on the North Shore on November 5.
The 44-year-old was reported missing by her partner after she did not return from her regular walk in Long Bay Regional Park.
North Shore police are treating the disappearance as a homicide investigation.
Police say they believe it is possible that her body will be located in a secluded area such as a green belt or rural bush reserve. They are not excluding areas outside of the North Shore.
The Police National Dive Squad has not yet been called to Auckland to carry out a search at Long Bay Beach, but the members are on standby should they be required, police said.
Chen's brothers flew to Auckland from China to appeal for any public information on her disappearance, saying they were "desperate" to bring their sister home.
Police are still seeking information from the public relating to Chen's disappearance.
They are urging any member of the public who has knowledge of her whereabouts to notify the OPERATION WAIAU enquiry team on 08000 CISSY [08000 24779] or call Crime Stoppers anonymously on 0800 555 111.
