A man accused of murdering his best friend has denied lying to police in the days after his alleged victim disappeared, a court has heard.
Bradley Scott Purkiss was the last person to see Risdon Vale tattooist Dwayne Robert Davies on May 26, 2017.
Mr Davies' body was found a week later in a shallow grave at Levendale.
Mr Purkiss stands co-accused for the alleged murder alongside Mr Davies' wife Margaret Anne Otto.
Both accused have pleaded not guilty.
Giving evidence to the Hobart Supreme Court on Tuesday, Mr Purkiss said he had not lied to the police when he was interviewed in 2017.
"I just had mistaken the days," Mr Purkiss said.
Mr Purkiss said when he told police he and his former partner Jillian Roberts had watched a movie at home after Mr Davies allegedly left Elderslie on May 26, he had been mistaken and meant the following night.
This contradicts evidence given by his father and brother the trio went shooting at Levendale the next evening.
Crown prosecutor Allison Shand suggested to Mr Purkiss he deliberately lied to police and omitted to tell them information related to Mr Davies' disappearance, which the accused denied.
"I've got no lies," Mr Purkiss said.
Mr Purkiss said he was actively trying to help police with their investigation.
"I was trying to be cooperative and was telling the truth," he said.
"It's quite hard to recall ... when you're in an interview with police."
When asked why in three police interviews he never mentioned going shooting at Levendale, Purkiss said he told police at some point between the interviews during transit.
Ms Shand alleged Mr Purkiss had lied to the court when giving his account on Monday and Tuesday and had constructed a narrative to fit the evidence of the trial.
Ms Shand suggested Mr Purkiss was using evidence, such as information in Ms Robert's statement to police she saw someone drive Ms Otto's car from Elderslie on the night of May 26, 2017, to construct his version of events.
"It's in Jill's statement so it is a fact," Mr Purkiss said.
"It is a part of this trial."

Ms Shand suggested Mr Purkiss thought he and Ms Otto could get away with the alleged killing if they "kept quiet" about what they had done.
"In May 2017, you were aware of a story of a man who got away with murder for eight years who was caught after bragging in a pub," Ms Shand said.
The court heard Mr Purkiss had told this story to others, including Mr Davies' sister Kelly Goss, some time before the alleged murder.
Ms Shand alleged Mr Purkiss said "loose lips sink ships" multiple times in the weekend after Mr Davies disappeared as a reminder to Ms Otto to not speak of their alleged murder plot.
The accused told the court he said the phrase in relation to him not wanting people to know he was growing cannabis in a shed at his Elderslie property.
