Officers are asking islanders to check their gardens, sheds, out-houses and fields for any sign of Richard Romeril.
States of Jersey Police would also like people to send their CCTV, dashcam, doorbell and honest box footage from the Ouaisne and Noirmont area.
Richard is 5ft 3in, of a stocky build with short, receding, dark hair and a moustache.
He was last seen wearing a brown or orange t-shirt with light brown shoes and dark socks and police now believe he was wearing blue denim jeans, despite photos showing him in dark shorts.
The 48-year-old was last seen leaving his home in St John at 8:30 am on Friday, 8 September.
He was then spotted on CCTV at B&Q at around 9:45 am, where he bought an orange bucket and other items.
At around 2:00 pm, his black Kia Sportage was found parked at Noirmont Point in St Brelade.
The search for Richard continued over the weekend with the police, Jersey Search and Rescue team and their search dogs, Jersey Fire and Rescue and their drones, the Ports of Jersey drone operator, the Coastguard and the French Search Helicopter.
Anyone who may have seen Richard or has any information is asked to call police on 01534 612612, option 2, option 4.
Alternatively, contact the independent charity Crimestoppers anonymously on 0800 555 111 or via their anonymous online form at Crimestoppers-uk.org
