Victims of serial rapist Malcolm Rewa are lobbying to have him tried for a third time for the alleged murder of Susan Burdett in 1992.
Teina Pora spent more than 21 years in prison for the rape and murder of Ms Burdett, before his conviction was quashed by the Privy Council in March 2015 and there's since been a compensation payment.
Malcolm Rewa was convicted of the rape of Ms Burdett but there were two hung juries over the murder charge. After his second trial in 1998, the solicitor-general imposed a stay of proceedings against further prosecution.
The police say they can't re-prosecute Rewa because of the stay of proceedings, but also because there's no new evidence.
Rewa was sentenced to preventive detention in 1998 for attacks on 25 women. He's eligible for parole in 2018.
Fairfax Media reports three of Rewa's victims want him prosecuted for a third time for Ms Burdett's murder and two of them have gone to court to have their name suppressions lifted.
They argue the stay of proceedings can be lifted by the solicitor-general in exceptional circumstances.
