A second vehicle tried to pull it free.
At the point tension came on to pull the trapped vehicle free, the beekeeper's foot came away from his leg. It was believed that his foot became caught in a loop in the rope or strop being used to pull the vehicle free.
The remote Pouto area, near the northern entrance of the Kaipara Harbour, is about 50km from Dargaville. Away from the single road to Pouto, some parts of the peninsula are so inaccessible that the beach on the western side is used to get in and out.
A spokeswoman for St John said the emergency service received a landline call at 8.43am on October 12 about the accident, but was not needed as the patient took himself to hospital.
A spokeswoman for Northland District Health Board said the patient was stabilised at Dargaville Hospital and then moved to Whangarei Hospital for further medical care. She said the person had since been discharged.
WorkSafe said it had started an investigation. The first stage of the inquiry would be to find if the injury was work-related.
Orthopaedic surgeon Professor Gary Hooper said had the accident happened higher up the man's leg, the larger bones would likely have stopped the limb from coming away.
"The rope would have been under a lot of pressure, a lot of force, and just cut right through like a guillotine."
Hooper, head of the orthopaedic department at the University of Otago, said it would be difficult to try and reattach the foot because of the limited use it would likely have provided.
He said amputations further down the leg often don't provide a benefit in function that people would experience with those reattached further up the limb.
