A man has been cut free by firefighters after his arm became trapped in a harvester in mid-Canterbury.
Emergency services were called to a property in Barhill between Methven and Rakaia just after 1pm.
A Fire Service spokesman said the man's arm had been caught in a harvester and had to be cut free.
He has been flown to Christchurch Hospital in a serious condition.
A St John's ambulance spokeswoman said the man was "very sick" by the time he was freed.
It is not known whether he has lost his arm.
