One of the leading supporters of Mark Lundy says he'll be ready to work towards an acquittal if a fresh trial is ordered.
Mr Lundy was released from Rangipo Prison near Turangi on Friday after being granted bail at a High Court hearing in Wellington.
The 54-year-old has been serving a life sentence since being convicted in 2002 of killing his wife Christine Lundy, 38, and their daughter, Amber, seven, at their home in Palmerston North 13 years ago.
Those convictions were quashed on Monday by the Privy Council in London, which said Mr Lundy should be retried.
West Auckland man Geoff Levick has campaigned for years for Mark Lundy to be freed and says he has as many as 20,000 thousand pages of research on the case.
Mr Levick said he will share his information with Mr Lundy's legal team and is ready with the results of his research, if a retrial is held.
"If the Crown says, right, we are going to have a retrial, I'll leap back into action again and assist the barristers to put the case together," he said.
