"Your sorrow is our shame and words are not enough."
Sinapati Sila, the father of the 23-year-old man, was fighting back tears when he read the message during an interview on One News tonight.
His son was found guilty on the fourth day of the jury's deliberations in a five-week long trial.
The prosecution had argued Sila deliberately drove into the crowd of partygoers, killing 16-year-olds Hannah Rossiter and Jane Young, injuring eight others and in total hitting 28 people during a seven-second angry rampage.
The defence said the driving had been the result of panic by Sila who had been under attack in the street in the minutes earlier, and had sped away for his own safety.
Today, his family told the broadcaster Sila was "very very sorry" for his actions.
Mr Sila said the family accepted the jury's decision.
"He is feeling very bad," Mr Sila said.
"And that he wished he could turn the clock back. As a parent this kind of sentiment is one way to help us realise where our son is at emotionally and spiritually."
Sila's sister, Epinesa, said she had read in a newspaper that Hannah's mother, Sally Rossiter, wanted to meet her daughter's killer and told her brother about it this morning.
She said Sila did not want to meet Ms Rossiter.
"Because he's just scared. He feels guilty enough," she said.
His cousin, Marina Tafua, said she thought Sila was afraid and ashamed.
"Because it's not something that he's proud of. And having to face the parents of his victims is going to be really really hard."
Ms Rossiter said she wanted to meet Sila face to face.
"I'd like to know if he feels remorse. I hope he does."
She said she thought it would be helpful to meet his family as well.
There had been a lot of tension in the courtroom, Ms Rossiter said.
"And it was hard for anyone to relax so there were times when there was tension between his family and friends and us."
The Sila family said they would discuss the potential of meeting the Rossiter family with a lawyer and their son tomorrow.
Sila has been remanded in custody for sentence on June 26.
