81-year-old Kiwi farmer throws water bottle at angry bull

An elderly man has had a lucky escape after he tried to stop a bull from attacking his ute by throwing a water bottle at it, followed by his hat.

The 81-year-old New Zealand farmer was filmed trying to shoo a large black bull named Rex away from his ute, which was parked in a paddock near Gisborne, reported Yahoo 7.

The footage was filmed by his son Whetu Konia and shows his father, known as "Mac", taking on the angry animal, which is butting against the vehicle.

Konia posted the footage to Facebook on Sunday with the caption: "81-year-old man vs Rex the Bull. Sort of funny after the fact, excuse the language."

The footage shows the bull sniffing around the wheels of the car before you can hear Konia saying "No, no, Dad - get back in here," as his father climbs over the fence, the Daily Mail reports.

He then says: "Oh my God, here we go. It's this guy's birthday today and he's not going to make 82."

"Dad! Get the f*** over here," he then yells.

"Oh f*** sake, get out! It's going to kill him."

Konia's father grabs a large, full water bottle and heaves it over his shoulder, before throwing it at the bull who is momentarily scared away from the vehicle.

The old man then stands next to the ute, stomping his feet and waving his arms around to keep it away from the vehicle.

Konia then says: "Dad, it's mad, get out!" as the bull grabs the water bottle in its mouth and shakes its head around and paws the ground aggressively.

As the bull heads back towards the ute it follows him around the other side, and he's forced to jump into the car to escape it.

But "Mac'' goes even further, jumping out of the car and taking off his blue bucket hat and flinging it at Rex in one final attempt to scare him away.

Konia, who is from Auckland, told One News he was visiting a cemetery next to a farm at Tikitiki, which is near Gisborne, with Mac and his two sons when the standoff took place.
