A racing car driver remains in Dunedin Hospital after a crash at Teretonga circuit in Invercargill.
Formula 5000 driver Stan Redmond (65), of Christchurch, was transferred from Southland Hospital to Dunedin Hospital by helicopter in a critical condition on Friday night.
He was earlier in the day involved in a collision with another car during practice. Acting Senior Sergeant Deon McNaught, of Invercargill, said inquiries were continuing. Police were working with motorsport authorities.
''It was a sanctioned meeting on a private track, closed to the public. It was just the fact that he's quite severely hurt that [means] police became involved.''
Snr Sgt McNaught said the driver was still in Dunedin Hospital yesterday.
