The legal team representing convicted murderer Teina Pora head to London today to prepare for the Privy Council appeal next week.
Pora, 38, was twice found guilty of the rape and murder of Susan Burdett in 1992 and has served 21 years in prison.
He denies having committed the crimes and, in recent years, a number of parties have voiced concern about the safety of those convictions, including Burdett's brother.
The team of three New Zealand lawyers will meet two London-based lawyers on Wednesday for a week of preparation before the hearing begins on 4 November.
