The would-be juror - who cannot be identified - made statements about the trial jury in an online blog soon after his jury experience.
In his posted comments, he said the people who remained in the jury selection room after he was excused were "overwhelmingly middle-class white women". He claimed some in the room had already said Tame Iti "scared" them.
"One of the jurors asked to be excluded because she was convinced he was guilty by how he looked," the blogger said. "She was refused her request to leave and heard the case. Another guy asked to be excluded because he thought the whole exercise was a waste of taxpayer money and resources and he was excluded. How does that work?"
Iti's lawyer Russell Fairbrother was not worried by the allegations. "We were quite happy with the jury," he said.
Iti has appealed against his conviction and sentence.
Yesterday, veteran protester John Minto claimed Iti had been transferred from Mt Eden to Waikeria Prison and Kemara to Springhill. "It seems a clear strategy on the part of police and prison authorities acting together to avoid a proposed prison protest," Minto said.
