Actor James Rolleston has been sentenced to 200 hours community work for causing a crash which injured himself and another person last year.

Rolleston, 20, was sentenced in the Opotiki District Court today to the community work, 12 months supervision and disqualified for driving for a year for the crash which left him and his friend seriously injured last July.

Supported by his family, the Boy and Goodbye Pork Pie actor officially entered his guilty plea to a charge of dangerous driving causing injury at the Auckland District Court in March.

In a statement at the time, the then 19-year-old said he always intended to admit his actions as he was "genuinely regretful" that they caused the accident.

"I am especially regretful for the harm caused to my good friend who was in the car with me.

"I am grateful that we both survived and have the opportunity to make something of the lives we have ahead of us, despite the fact that I have a bit of recovery still ahead.

"Not everyone is that fortunate. I have learned to appreciate life a lot more and to be grateful for what I have," the actor said.

Court records showed Rolleston was driving at a speed considered "dangerous to the public" and caused injury to Kaleb Maxwell, who was a passenger in the vehicle, on July 26, 2016.

Rolleston was taken to Waikato Hospital's Intensive Care Unit where he remained for nearly a month.

Maxwell was also seriously injured in the crash.

The maximum penalties for a dangerous driving conviction were a $20,000 fine and five years in jail.
