Convicted murderer and rapist Liam Reid is in court attempting to stop a television company making a documentary about his crimes.
Reid is serving a minimum 23-year sentence for the 2007 rape and murder of Christchurch woman Emma Agnew, and the rape and attempted murder of a 21-year-old student in Dunedin days later.
He hopes to ask the Governor General to use her prerogative to allow him to appeal his convictions or reopen his trial.
His legal team claim there is new information warranting the rare step.
On Wednesday, at the High Court at Auckland, he sought an injunction to stop South Pacific Pictures broadcasting a documentary about him.
He argued the television show could put at risk his rights to a fair hearing in any appeal or future re-opened trial.
However, lawyer Simon Mount, representing South Pacific Pictures, argued Reid's injunction should be struck out.
He said Reid had already used up his maximum number of appeals against conviction after being found guilty in 2008.
He acknowledged people like Reid, who had exhausted all their appeals, could still apply to the Governor General if special circumstances arose warranting a fresh appeal.
But in Reid's case, no submission had been made to the Governor General and his case was not before any court, meaning any injunction would be speculative and unlawful, Mr Mount said.
As one of New Zealand's biggest production companies, South Pacific Pictures is known for shows Outrageous Fortune, Westside and Shortland Street.
It is also known for making true crime shows, including multi-episode Forensics NZ.
Mr Mount said the documentary about Reid planned to focus on the science investigators used to charge and convict him of his crimes.
He said other television shows about Reid had already been broadcast and were still available, including TVNZ's 2012 Beyond the Darklands documentary.
Last June, Reid made headlines when he married disgraced lawyer Davina Murray, who was found guilty of smuggling him an iPhone, cigarettes and a lighter into Mt Eden Prison in 2011 while he was her client.
On Wednesday, Reid smiled at his wife, who was supporting him in the public gallery, before sticking his finger up at media filming and photographing him.
Justice Kit Toogood has reserved his judgement in the case.
