There is a growing movement to bring the show back to TV2.
Sensing Murder pulled in about 200,000 viewers an episode over five series and twice won best reality series at the Qantas Media Awards.
It featured Kelvin Cruickshank, Sue Nicholson and Deb Webber visiting the scenes of violent deaths and describing visions they claimed to be experiencing.
Nicholson and Webber have already signalled their support for a return on a Facebook page encouraging people to sign a petition and lobby TVNZ.
Nicholson said there was also interest from the "other side" and one victim had spoken to her about being involved.
"She said to me 'I've been on telly. I always wanted to be on telly'."
Creator David Baldock said he was encouraged to hear Facebook group Bring Back Sensing Murder had picked up more than 1000 members in 24 hours.
"Sensing Murder isn't dead.
"It's just resting," he said.
Baldock said he owned the rights to the show in New Zealand and had been in discussions with TVNZ.
The broadcaster had not said "no" to a sixth series but told him he would need to find a sponsor.
Petition organiser Craig Tristram has defended the psychics after a sceptic offered them $100,000 if they could prove they talked to the dead.
He said murder convictions would be gained on the evidence of psychics if police forces across the globe stopped feeling silly about accepting their evidence.
