A 72-year-old Waikato man has died after cutting himself with an angle grinder on a Bideford farm, near Masterton.
The accident took place at about 10.30am today on a farm on Maringi Rd.
Senior Sergeant Mike Sutton said the man had been working by himself on the bucket of a digger when he cut his leg with the angle grinder.
"He was working on that with the grinder and that is when the accident occurred and that has put a severe cut into his leg."
The man got to his car but was unable to get to help.
He was found shortly afterwards by a farm worker.
"It's very tragic. We've referred the matter to the coroner," Mr Sutton said.
The man had been visiting family and helping out on the farm, and was not a farm worker, Mr Sutton said.
A post mortem would be conducted and police had referred the death to Worksafe.
