A couple of kilometres away they caught up with her and tensions rose, which led to the charges before the court.
At his previous appearance, Moka was adamant Mrs Faumuina drove into his daughter and should have been charged too.
However, police have confirmed there will be no further charges laid.
"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."
The rugby lover said his appreciation of Faumuina as a player made the situation all the more regrettable.
The altercation meant the burly forward'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.
His wife gave birth to the couple's second child while he was overseas.
Moka and Kahui will be back in court in February.
