Christchurch police will begin searching parts of Ellesmere, Lincoln and Halswell tomorrow for clues about the disappearance of Michael McGrath.
McGrath, 49, was last seen at his house on Checketts Ave in Halswell on May 21.
Detective Inspector Darryl Sweeney said the new search phase was based on information and sightings related to McGrath's disappearance.
Police are also continuing to pick through rubbish at the Kate Valley Landfill. They expect to be there a few more weeks, having already searched through around 2000 tonnes of rubbish.
"Operation Renovation continues as a major investigation for the Canterbury CIB and the investigation team are committed and driven to solve the case and bring some closure to Michael's family," Sweeney said.
