The search for a missing Christchurch real estate agent remains focused on waterways south of Christchurch, but police are still trying to track exactly where her alleged kidnapper's car went the day after Yanfei Bao disappeared. A dive squad has been searching the Halswell river and looking again in waterways around Greenpark & Lake Ellesmere, with land searches too. Yanfei Bao went missing more than two weeks ago and a man's in custody charged with her kidnap, but she is yet to be found. A forensic examination's been carried out at a Trevor Street house that was on the market with the agency Ms Bao worked for. The Detective Inspector Nicola Reeves says they've had more than 200 hundred tips off which have helped direct them to the current search area. She says some of Yanfei Bao's China based family are making arrangement to come to New Zealand.
