Lawyers for the convicted double-murderer, Mark Lundy, are due to make a second attempt at overturning his conviction.
Lundy is serving a life sentence for killing his wife and daughter in the family's Palmerston North home on August 29, 2000.
In 2002, Lundy lost an appeal against his conviction in the Court of Appeal, and had his minimum non-parole period increased to 20 years.
Lundy's lawyer, Christopher Stevenson, has confirmed he will soon file papers to again appeal against the conviction but declined to give further details.
In January last year, a fund to pay for the court action was set up by Lundy's supporters who believe there were inconsistencies in the police case.
