Mark Lundy told police that his life was absolutely destroyed in the weeks after the murders of his wife and daughter.

Lundy is on trial for the murders of Christine and Amber Lundy in the High Court in Wellington.

A police video taken in September 2000, two after the murders were carried out, has been played to jurors as part of the evidence given by Detective Inspector Stephen Kelly.

The first question he asked was how Lundy was feeling.

Lundy said his life was destroyed, but he’d been trying to do something every day.

“I hate going out in public because people are so wonderful and I don’t know what I’m going to do if someone walks up and gives me their condolences. I’m scared of breaking down.”

Lundy also told Detective Inspector Stephen Kelly he wasn’t sleeping well.

Brother Craig Lundy had told police Mark Lundy was celebrating the night his wife and child were killed.

Lundy explained in the interview he was drinking rum in his room. He agreed he was celebrating, saying he “was pretty pumped up because we, on the Friday, were launching a new product.”

Lundy said Christine Lundy had told him to enjoy himself, and have the night off.

Earlier jurors heard from the lawyer of Witness X.

The witness says while the pair were in prison together in 2000, Lundy told him he would’ve got away with it if his daughter hadn’t come in and seen what he was doing to his wife.

Witness X’s lawyer Kirsten Gray said in January 2014 her client gave her a letter he wanted her to hand on to a judge explaining the apparent confession in a bid to get bail while on remand in custody.

Ms Gray said she’d advised him against it, saying the letter wouldn’t be part of his bail application.

“I would’ve said something along the lines of, ‘it’s not a bartering situation, where you provide information and then you get a benefit.’”
