Key evidence

• Blood spatter from Christine and Amber Lundy was found on walls, down the hallway and in nearby rooms, but no bloody footprints we found

• A senior police officer said he was led to believe a video taken of officers not wearing protective clothing was filmed on the day the bodies of Christine and Amber Lundy were found, but it was a week later

• A forensic scientist gathered blood from a broken window at the home that could have come from Mrs Lundy

• Unidentified fingerprints and shoe prints had been lifted from the Lundy property

• Other evidence including a cigarette lighter and shoe prints on neighbouring properties were also gathered

• No fingerprints in blood were found in Lundy's car

Blood stains from Christine Lundy and her daughter Amber were found throughout the family home, but their killer was careful not to leave any bloody footprints, a court was told today.

Grisly details emerged in the High Court at Wellington today of blood spattered at the crime scene in the Lundy family home in Palmerston North.

At times Mark Lundy, 56, accused of their murders, bowed his head and closed his eyes while listening to the evidence.

Mrs Lundy, 38, was killed as she was lying in her bed and 7-year-old Amber was killed in the doorway of her mother's bedroom with a tomahawk or similar type weapon.

ESR forensic scientist Bjorn Sutherland said DNA testing showed blood that could have come from Mrs Lundy was spattered across every wall in the bedroom and across the ceiling.

Brain tissue was also found on the bedside table, he said.

Blood from Amber, found lying halfway out of her mother's room and into the hallway, was found along the hallway and in nearby rooms.

A smear of her mother's blood was found on her leg, Mr Sutherland said.

Smears of blood that DNA testing showed could have come from Mrs Lundy were found in the toilet by the lightswitch as well as a drop on the kitchen floor.

Blood and tissue that could have come from Mrs Lundy were also found on a chopping board in the kitchen.

Luminol testing of rooms in the house showed no bloody footprints at the scene, Mr Sutherland said.

"It could be due to the assailant not stepping in the blood while leaving the scene."

Mr Sutherland also examined some of Lundy's belongings, two rings and a pair of glasses, but no visible blood was found.

Earlier a senior police officer who was part of the murder investigation told the court he was misled by evidence he was shown earlier in the murder trial.

On Monday Detective Senior Sergeant Nigel Hughes told the court that all officers who entered the crime scene were wearing paper overalls, booties and gloves.

However, in footage of part of a video shown to the jury by defence lawyer David Hislop, an officer appeared to be wearing no protective clothing and was watching television.

Today that video was shown to Mr Hughes and the jury in full and Mr Hughes said he recognised the video and said the footage was taken on September 7 and the officer in the room he now recognised as being himself.

He said he was "misled" on Monday because he was led to believe the footage was shot on August 30, which Mr Hislop denied.

Also giving evidence today was senior crime officer David Andrews who lifted fingerprints and shoe prints from the scene and neighbouring properties.

Mr Hislop put to Mr Andrews that some of the prints taken from the conservatory had remained unidentified, but Mr Andrews had not seen the test results.

Police National Headquarters' fingerprint manager Eugene Wall told the court he used a specialist polilight to examine Lundy's car on the evening of September 2 in an attempt to find bloody fingerprints in the vehicle, but none were found.

The trial in front of Justice Simon France continues.
