It's alleged there was an initial flashpoint before Mrs Faumuina drove away in her husband's All Blacks Ford Kuga, pursued by the father and daughter.
A couple of kilometres away they caught up with her and tensions rose, which led to the charges before the court.
Moka has not pleaded in court to the charge and said he had not yet decided how he would plead, but he was adamant Mrs Faumuina should be before the court too over the standard of her driving.
"We just want justice," Moka said.
"But there only seems to be justice for certain people in this country. If you're related to the All Blacks, you can do anything."
Counties Manukau police confirmed today the investigation had been completed and there would be no further charges laid.
Mrs Faumuina had called her husband from the scene and he arrived after police.
Being a diehard All Blacks fan made the incident more distressing, Moka said today.
"He's an icon of mine in the rugby world. I love rugby and he's a champion in my books."
The altercation meant Faumuina's departure for the United States on the All Blacks tour was delayed by a day but he started in two of their three games while overseas.
Moka said all the focus was on Mrs Faumuina but his actions were also those of a protective parent.
"I've come to court for assault, which I own, but any parent would react in that sort of manner if that happened to their kid," he said.
"I dropped tears for three days. No one cared about my daughter."
Mrs Faumuina was being sought for comment.
Moka was remanded on bail to appear in court again next month.
Kahui - who faces charges of driving while forbidden and threatening with intent to frighten - will appear on the same day.
