Police searching for a missing Christchurch man have released flyers in a renewed effort to find him.

Michael McGrath, 49, has been missing for almost two weeks and police say they have grave concerns for his wellbeing.

This morning, authorities announced they were releasing a special notice flyer, to be distributed to residential homes and retail businesses in the Halswell area.

The flyers include a photo of McGrath and pictures of his blue bicycle, dark coloured helmet and navy blue vehicle.

Police are also appealing for any CCTV footage or photographs that may show him in and around the Halswell area - or wider area - in the past two weeks.

There is a particular interest in any footage that may have captured the missing man on Sunday, May 21, Monday, May 22 or Tuesday, May 23.

Police say it is possible McGrath had been wearing blue jeans, a black thermal long-sleeved top, a black T-shirt with red lettering on the sleeve - possibly RBK for Reebok - Hi-Tec branded shoes or a crew neck jersey with a chunky knit/mid-grey colour, mixed with white.

"Mr McGrath may have been driving his blue 1994 Subaru station wagon or riding his bicycle. The car, bicycle and helmet have been located.''

Detective Inspector Darryl Sweeney said: "The overall focus of this investigation remains on finding Mr McGrath or any evidence relating to his whereabouts.''
