Police searching for Christchurch man Michael McGrath, who has been missing for nearly two weeks, are knocking on doors and distributing fliers.
Mr McGrath, a builder, lived alone. His brother has said such a disappearance was completely out of character.
Police involved in the search were concentrating on the Halswell area, and wanted anyone there who had a security camera on their property to come forward.
Police have previously asked for sightings of Mr McGrath cycling through the area between 21 and 23 May.
They said the focus of their search in the next few days would be Checketts Avenue.
