New Zealand has seen a few high profile miscarriages of justice in recent years, yet successive governments have ruled out the possibility of setting up a body - similar to the Criminal Cases Review Commision in the UK - to investigate potential miscarriages of justice. Justice William Young said courts could benefit from having a Criminal Cases Review Commission, like that established in the UK - an idea backed by the Police Association and most political parties. In a rare interview - which you can listen to here: Supreme Court Judge interview - the Justice discusses welcoming the introduction of such a body - despite being recently dismissed by the Ministry of Justice. There is also a handy guide to the New Zealand post-conviction relief here: Reviewing Criminal Cases. While in 2012 - Malcolm David Birdling published a PhD thesis examining the two systems (available here): Corrections of Miscarriages of Justice in New Zealand and England and Wales (PhD Thesis).
