Convicted rapist and murderer Teina Pora is due to learn on Tuesday night whether his appeal to the Privy Council in London is successful.
Pora, who was freed on parole last April, spent 20 years in prison for the 1992 rape and murder of Aucklander Susan Burdett.
His case has been reviewed by a Privy Council panel of five judges, including NZ Chief Justice Dame Sian Elias.
Their decision will be delivered in the UK capital at 10pm (NZT).
Pora has twice been convicted of Ms Burdett's rape and murder but his legal team have argued that evidence shows serial rapist Malcolm Rewa was responsible.
