A motorcyclist remains in a critical condition after a crash at Levels Raceway in Timaru.
St John ambulance was called to the raceway shortly after 11am today after a motorcycle crash, a spokesman said.
The man, believed to be 50-year-old Shaun Harris, was flown to Christchurch hospital, and a spokeswoman said he remained in a critical condition in the intensive care unit on Saturday evening.
The raceway was hosting the New Zealand Superbike Championships over the weekend.
South Canterbury Motorcycle Club declined to comment.
