Suppression has been lifted on a claim that David Bain's 111 ambulance call on the day of the murders of five members of his family contained an admission that he had shot someone.
The Supreme Court today lifted orders preventing publication of an earlier judgment which ruled a part of the recording of the call was prejudicial and could not be played to the jury.
The Crown claimed Mr Bain said "I shot the prick," or "I shot that prick" on the tape, but forensic opinions were divided whether the sounds were words or meaningless exhalations of breath.
Bain's lawyerssay no-one can agree what was heard was even words.
"It's not evidence, it's nonsense," Helen Cull, QC told the Supreme Court, Stuff reported.
The Supreme Court ruled the jury in the trial of Mr Bain should not hear the interpretation the section of tape had been given.
The alleged hidden message in the tape was discovered in 2007 when the 111 recording played to the jury at the first trial was sent to Dunedin company Strawberry Sound.
Experts were divided on whether the sounds were words or nothing more than breathing modified by random lip and tongue movement.
Mr Bain was last week found not guilty of the 1994 murders.
