Murder accused Antonie Dixon wrote instructions for one of the women he attacked with a samurai sword outlining what she should say when questioned by police.
Crown prosecutor Simon Moore produced a letter with the instructions this afternoon in the High Court at Auckland as he cross-examined Dixon on his state of mind when he attacked two women and fatally shot a man in 2003.
Dixon, 40, is on trial on eight charges including murdering James Te Aute, who was shot dead in Auckland, and causing Renee Gunbie and Simonne Butler grievous bodily harm with a samurai sword at Pipiroa, near Thames in 2003.
He was found guilty of the charges in 2005 but the Court of Appeal later ordered a second trial, suppressing its reasons for quashing his convictions.
The letter was seized by police from Ms Gunbie's mother's home in March 2004 and was undated.
In court today, Dixon said he wrote the letter while in prison in Mt Eden when Ms Gunbie visited him.
The pair had written the letter together because Ms Gunbie could not write as she had no right hand and he was helping her as she dictated the contents to him, he said.
Dixon denied the letter was meant to be instructions as to what to tell police.
The letter in Dixon's handwriting outlined how Ms Gunbie should tell police she saw Ms Butler pour methamphetamine into Dixon's orange juice on the day of the attack.
The letter outlined how Ms Gunbie should describe the effects the "P" had on Dixon that day.
Mr Moore asked him why on three occasions when he had met doctors Dixon made no mention that he had taken P that day until he was admitted for a second time to the Mason Clinic when he told a doctor meth had been put into his drink bottle.
Part of the letter says "you saw her put meth into orange juice 500mils and hand it to me (the main thing) in bed".
Another extract said "make sure you stick to the story, don't sway under cross-examination, don't act like you don't know, don't sway if they hassle".
Dixon said this was Ms Gunbie's version of what happened.
"So this is you helping Renee record what she saw Simonne doing," Mr Moore asked.
Mr Moore also revealed Dixon had 159 convictions with the earliest conviction recorded in 1984 in the Auckland District Court.
Mr Moore asked him if he had cut Ms Butler's hair before as a punishment.
Dixon said he had cut it because he believed she had a listening device under her hair.
Mr Moore challenged Dixon quoting a psychiatrist that Dixon had told he cut people's hair when they were rebellious because that was what his mother did to punish him.
"There are times when you get so angry and so violent that you lose it," Mr Moore said.
"I'm not an angry person," Dixon replied.
"Do you lose it," Mr Moore asked.
Dixon replied he had reacted the way he did at times because he believed certain things were happening to him.
Mr Moore asked if prior to January 2003 he had been violent with either women and if either had ever brought charges against him.
Dixon said he had been violent once towards Ms Butler and had bitten Ms Gunbie once.
Dixon became increasingly frustrated with Mr Moore, calling him rude.
"I'm here to teach you and you are here to crucify me, so where's the cross?"
The trial continues tomorrow.
