Rubin "The Hurricane" Carter will meet convicted murderer David Bain inside Christchurch Prison on September 20.
Bain campaigner Joe Karam released details of Mr Carter's New Zealand itinerary yesterday. Mr Karam helped raise $80,000 to bring the former American boxer, now a justice campaigner, to New Zealand to meet Bain andhold meetings in several cities.
Mr Carter was wrongly convicted of the murder of three white people in 1966 and languished in prison for 19 years until the Supreme Court overturned his conviction.
Mr Carter was a top contender for the world middleweight title before his imprisonment. Denzel Washington played him in the movie Hurricane.
His autobiography, The 16th Round: From Number One Contender to Number 45472, was a best seller and he was immortalised in Bob Dylan's 1975 song.
Mr Carter will speak in Auckland on September 21, in Wellington on September 26 and again in Auckland on September 30.
He has been the executive director of the Association in Defence of the Wrongly Convicted since it was set up in May 1993.
Bain was found guilty in 1995 of murdering his mother, father, brother and two sisters at their Dunedin home in June 1994. He has maintained his innocence.
He will not be eligible for parole until 2011. An application for a pardon was made three years ago.
The Governor-General's decision on that application has been deferred awaiting the outcome of a Court of Appeal hearing on some of the evidence used to convict Bain.
The High Court hearing of that application will take place in November and the Court of Appeal hearing will follow.
