Saber, a producer on Hutchence's self-titled solo album released in 1999, says he and Hutchence had been working on music together not long before he died.
"Me and him sort of connected and started writing towards the end. It's sort of like a little treasure trove of stuff - essentially there were vocals and ideas and that's the stuff that I'm reworking and we're going to be releasing," Saber told AAP.
Creevey has also been gathering artefacts and documents belonging to Hutchence to build up a picture of the final years of his life.
Along with diaries and notes of Hutchence's, Creevey says he also developed film in a disposable camera the singer used not long before he died.
All of this will be used in a documentary that Creevey plans to release next year, to mark the 20th anniversary since Hutchence's death.
When news first surfaced in May of a potential Hutchence release, INXS manager Chris 'CM' Murphy threatened legal action against anyone who released anything under the INXS and Hutchence copyright.
Creevey denies that Murphy has any claim over the new music.
