The search for missing real estate agent Yanfei Bao is continuing in a rural area south of Christchurch.
The 44-year-old vanished from the suburb of Hornby almost two months ago.
Police and a specialist search team were out in Greenpark on Wednesday, combing grass, bush and a stream on the side of Hudsons Road.
Greenpark, which is 30 minutes from Christchurch, has been a focal point of the investigation.
Previously police had focused their search on farmland and a pond at a farm property.
Bao was last seen on 19 July.
Tingjun Cao, 52, was charged with kidnapping Bao and later charged with her murder. Cao has pleaded not guilty.
