Arguments surrounding non-scientific evidence which will be heard during Mark Lundy's murder re-trial, were heard in the High Court at Wellington today.
The double-murder accused was not at the court today during submissions.
Justice Alan MacKenzie suppressed all details surrounding the evidence discussed and submissions from the Crown and defence lawyers about the evidence.
A second pre-trial focusing on scientific evidence would be held in June.
Lundy will face a retrial for the murders of his wife Christine and 7-year-old daughter Amber, in Wellington on February 9 next year.
Last year Law Lords at London's Privy Council quashed his convictions and ordered a new trial.
In 2002, Lundy was sentenced to a jail term of at least 20 years after being found guilty of killing his wife and daughter.
He was released on bail last October to a location that is suppressed.
