Stuart Landsborough, a long-time sceptic and the founder of Wanaka tourist attraction Puzzling World, has reissued a challenge to the show's psychics to prove their paranormal powers.
Mr Landsborough has put up $100,000 each to the producer of Sensing Murder - Ninox Television - and the three psychics who appear on the show, Deb Webber, Kelvin Cruickshank and Sue Nicholson.
He has called into question the techniques used by the psychics.
He wants the show's producers and group to undergo a test he devised to prove psychic ability.
The test involves the psychic finding two matching parts of a note hidden within 10m of each other.
Sensing Murder producers turned down the challenge last year and claim the show is not about finding objects, but in revealing new information to assist police with unsolved murders.
Mr Landsborough reissued the challenge after the last series of the TV show finished this month.
Producer Geoff Husson said in an email the processes and procedures used on Sensing Murder were constantly reviewed, updated and refined, and "as scientific as we can possibly make them".
The TV show's psychics did not have the ability to communicate with inanimate or non-living objects, such as "pieces of paper", he said.
Mr Landsborough's "test" was ill-conceived and would not result in any kind of positive result or measurement of psychic ability.
Sensing Murder psychics have not solved any of the 20 cold cases featured on the programme, but police have investigated some of the information they claim to have discovered.
