The chair of the Parole Board has floated the idea of pre-screening those applying for parole to see if they stand a realistic chance of succeeding.
Judge Carruthers made the suggestion in a speech at Parliament on Wednesday, saying the move would save time, money and distress.
Judge Carruthers says 70% of parole hearings are declined and many decisions are easily predicted.
He says the board and the inmate know that, but by law everyone must be put through the agony and distress of a hearing.
The move would require a law change.
Justice Minister Simon Power says he is considering the idea and is asking for feedback.
