Convicted child sex abuser Peter Ellis has renewed calls for an independent body to look into alleged miscarriages of justice.
Mr Ellis, who was jailed for almost seven years after allegations of abuse at the Christchurch creche where he worked in the 1990s, has long protested his innocence.
In February he will lodge a fourth request for a pardon, based on new evidence about child witnesses, Radio New Zealand reported.
The pardon system allows the Governor-General to pardon a convicted offender, reduce sentences or send cases to a retrial on recommendation from the Minister of Justice.
Mr Ellis also wants an independent body established to look at alleged miscarriages of justice - something former Justice Minister Simon Power said had merit in his valedictory speech.
