One of the occupants suffered multiple rib fractures.
When spoken to by police, Rata admitted he was looking at the crash and expressed his remorse to the victims.
On behalf of the victim, police were seeking reparation of $6500 to cover the cost of the victim's medical costs and extra cost of buying a replacement vehicle.
Rata's counsel Wayne Dollimore said his client could have issues paying reparation but he was keen to attend a restorative justice conference.
He was convicted by Community Magistrate Ngaire Mascelle and remanded on bail to attend the conference to reappear for sentencing in November.
