A 25-year-old Auckland man broke both wrists and his nose after falling down a 20m bank while mountain biking in the Tongariro Forest, in the central North Island.
Youthtown Trust Rescue Helicopter spokesman Hendry de Waal said the man was on the 42 Traverse mountain biking track when the accident happened.
He was airlifted to Rotorua Hospital after a long-line was used to rescue him.
