A young mountain biker was injured during the national schools championships, held in Dunedin at the weekend.
Cycling New Zealand events director Janette Douglas confirmed the teenager was flown to Christchurch Hospital, after he crashed on Signal Hill yesterday morning.
While he was a registered rider, he was not racing at the time of the event, she said.
"[He] crashed while out practising and was attended to by the Red Cross, the event medical personnel.
"His condition at this time is unknown, but the event team are in contact with his parents."
The championships, which were hosted by Mountain Biking Otago, attracted competitors from 110 schools.
Competitors raced in a number of events including enduro, downhill and cross-country.
Ms Douglas declined to disclose how old the teen was but confirmed he was from the "Otago region".
Mountain Biking Otago Club president Kristy Booth declined to comment.
St John media spokeswoman Neha Concisom confirmed St John had attended a "crash" incident but she did not have any further detail.
They received a call shortly after 8.40am yesterday.
She could not confirm the mountain biker's age.
