Justice Minister Judith Collins has admitted convicted rapist Teina Pora, who has spent the past 20 years in prison, could be innocent.
In an interview on RadioLive this morning, Ms Collins was asked whether there was a possibility Pora could have been wrongly convicted.
"Of course - and I never make statements about somebody's guilt or innocence because I don't know,'' she replied.
"I am not in the court now ... what I know, from time to time there will be people who are wrongly convicted.''
Act leader John Banks, who was Police Minister at the time Pora was charged with the 1992 murder of South Auckland woman Susan Burdett, this week said he now believed Pora to be innocent.
