It was continued today on the basis of the accused's mental health.
Member's of Sikei's family were in court to face the accused.
They wore T-shirts adorned with Sikei's face and the words "fly high".
Last month Sikei's brother Semisi spoke about the family's loss.
"The story we have been told is that Rima was in the car with his friends and another car came up," Semisi Sikei said.
"The others got out of the car and started smashing up the car Rima was in.
"My brother and his friends jumped out and started to fight them off - but the other car had weapons.
"My brother tried to tell them to drop the weapons …
"Rima was in the wrong place at the wrong time."
Sikei was a promising rugby player who worked as a landscaper and volunteered in the community for various groups.
He mentored young people and hoped to join the police.
"He was just a really lovely guy, everyone got along with him," said Semisi Sikei.
"He was a really nice person … he was really lovable, he always had a smile on his face."
