A pre-trial hearing of scientific evidence is underway at the High Court in Wellington ahead of the retrial of double-murder accused Mark Lundy.
Lundy is charged with murdering his wife Christine, 37, and daughter Amber, 7, at the family's Palmerston North home in August 2000.
Last October the Privy Council at London overturned his convictions for the murders of his wife and daughter and ordered a retrial, which is set to take place in February.
All arguments and evidence presented at the pre-trial hearing today has been suppressed in an order by Justice Stephen Cos.
Justice Cos says there's a risk that if the evidence is reported on it could prejudice a fair trial for Lundy.
The 56-year-old had spent 12 years behind bars before his convictions were overturned.
Lundy is currently on bail at a Taupo address.
