Today, Sean Hansen, who was a police detective at the time of the murders, explained to the court how he was put in charge of the examination of Lundy's car in September 2000.
"The process was to locate every item that was in the car and make an inventory of what we found," he said.
Mr Hansen told the court that the car was kept at the forensics bay at Palmerston North Police Station, where entry was by key only.
He said while examining the car he was dressed in protective clothing, to ensure nothing was contaminated.
Among the items found in the car was a black suit bag which contained "a number of items in it including some clothing items", Mr Hansen said.
Inside the bag were green trackpants, a size XXL navy, purple and tan striped polo shirt, underwear, socks and other items of clothing.
Mr Hansen said he looked "generally and cautiously" for any signs of blood on each item, before individually placing each item into sealed exhibit bags, which were locked away.
Mr Hansen told the court it was common for police to take items of clothing from those potentially involved in cases like this one.
He said at the time he considered Lundy to be "a victim".
A dispute later arose over whether a woman's silver bracelet was found on the front passenger seat of Lundy's car.
Mr Hansen told the court he made note on September 3 that he had found a woman's silver bracelet on the front passenger seat.
However photos shown to the court revealed the bracelet was not visible on the front passenger seat of the car.
Mr Hansen also recalled a conversation he had with Lundy about the bracelet.
He alleged that Lundy told him the bracelet must have ended up in the car when Lundy and Christine went to Hamilton on a business trip.
Lundy allegedly told Mr Hansen that Christine had grabbed a handful of jewellery and put it in her handbag before they left.
Mr Hansen alleged Lundy told him he could only imagine that was how the bracelet ended up in the car.
The court later heard that family friends did not believe the bracelet belonged to either Christine or Amber.
The trial in front of Justice Simon France and a jury of five women and seven men continues.
Key items of evidence:
• Several items were found in Lundy's car including a silver woman's bracelet, and a size XXL navy, purple and tan striped polo shirt.
• Lundy allegedly told the police officer in charge of examining his car that Christine must have left the bracelet in the car while they were travelling on business.
• Several of the family's friends said they did not believe the bracelet belonged to either Christine or Amber.
• Lundy's car was kept at a forensic bay at Palmerston North Police Station while it was examined. Officers wore protective clothing while examining the car to prevent contamination.
• The police officer in charge of examining the car said he found the bracelet in the front passenger seat, however a bracelet is not visible in photographs from the inside of the car on the front seat.
