One person has been airlifted to Christchurch Hospital following a water-related incident at a lake near Twizel in Canterbury.
Emergency services were called to Lake Ruataniwha in the Mackenzie Basin about 3.30pm Thursday.
It was understood a child was injured. A witness on the scene told Stuff he saw emergency services help a young child before police asked him to launch his boat elsewhere.
St John sent an ambulance, a rapid response vehicle and a doctor to the scene before the person was flown to hospital in a critical condition, Stuff reported.
