Wei Kiong Lew (30) last month admitted charges of aggravated careless driving causing death and injury from the November 29 crash.
At an appearance before Judge Kevin Phillips yesterday, he was convicted of those charges after no evidence was offered on alternative charges of dangerous driving causing death and injury.
Crown counsel Robin Bates, on behalf of Timaru Crown counsel Andrew McRae, said the alternative charges were no longer sustainable. No evidence would be offered. The crash happened on State Highway 1 near Waianakarua, about 20km south of Oamaru, about 5pm.
Motueka motorcyclist Craig Alan Chambers died at the scene. Mr Bates said Lew was driving on State Highway 1 in a single southbound lane separated from two northbound lanes by double yellow lines.
At some stage, Lew crossed the yellow lines into the northbound overtaking lane.
He rounded a moderate right bend and continued travelling in the lane. Some vehicles were overtaking a vehicle towing a horse-float. Lew continued towards them in their lane.
One car driver and a Laverda motorcycle rider took evasive action. But a wing mirror on each was struck by Lew's vehicle.
Another car swerved and avoided a collision. Craig Alan Chambers, riding a Harley-Davidson motorcycle directly behind that car, swerved right but Lew's vehicle struck the front left of his motorcycle.
At the time of the impact Lew's vehicle was travelling at 120kmh. Lew did not brake or attempt to move back into his correct lane before the impact.
Mr Chambers suffered massive trauma to the left side of his body and was flung into a barrier and then outside the southbound lane. He died of his injuries at the scene.
Lew's vehicle spun and collided with a station wagon that had been travelling behind Mr Chambers' motorcycle. Both the driver of the station wagon and its front-seat passenger received extensive bruising.
After skidding into another car also heading north, Lew's vehicle came to a stop. Lew's partner was airlifted to Dunedin Hospital with serious injuries and in December was transferred to Singapore to continue her medical treatment.
The station wagon driver and passenger, taken by ambulance to Oamaru hospital, were discharged later in the day.
Judge Phillips remanded Lew for possible restorative justice, pre-sentence and emotional harm reports, victim impact statements and sentence on June 3.
