Double killer Graeme Burton is lodging a complaint with the Broadcasting Standards Authority (BSA) over "inaccuracies" in a television programme about his life.
The series, Beyond the Darklands, profiles the country's worst criminals, examining their backgrounds to attempt to explain how they commit their crimes.
The Burton episode followed his path from his Hutt Valley childhood to his slaying of Lower Hutt man Karl Kuchenbecker in January 2007. He was on parole at the time after serving 14 years for murder after stabbing Paul Anderson to death outside a Wellington nightclub in 1992.
He is now serving another life sentence with a minimum non-parole period of 26 years.
Burton's lawyer Peter Tomlinson told the Sunday Star Times that Burton had watched the programme in prison and was concerned it contained` "various factual matters that are inaccurate, just wrong and a couple of serious ones".
He said that a complaint would be laid with the BSA within the next few days.
The episode was due to have been shown earlier last year but was pulled because of Burton's impending trial for the attempted murder of another prison inmate with a hand-made knife in Auckland's maximum-security prison at Paremoremo.
He was later found guilty and is due to be sentenced on Friday.
