Horse riders and farmers fed up with unmanned aerial drones traumatising animals want to start shooting them "out of the sky".

After a Dannevirke horse-rider posted on social media about being harassed by a drone operated by an unseen person, a host of people suggested drones should, and could, be shot if they flew over a farm and were worrying animals.

When approached by Hawke's Bay Today to clarify whether a drone could be legally shot at over a farm, the Police said a number of agencies, including CAA and the Privacy Commissioner, had a role to play in relation to the use of drones.

"If a remotely piloted aircraft operation causes a safety risk to persons, property or other aircraft, police will respond and take all the details for forwarding to the CAA.

"Police access every situation on its merits.

"Any person using a firearm must do so lawfully and there are a range of offences that can apply based on the facts of each situation."

The use of drones is restricted under the Civil Aviation Act, which states that drone operators usually need consent from land and park owners prior to flying over either council-owned or privately-owned land.

The act also ensures drones must remain within the controller's line of sight, unless special permission is obtained.

However, Keiasha McGhie from Dannevirke said she had now has several unfriendly encounters with unmanned craft with no controller in sight that had left two horses "traumatised".

"I ride my horses at Herbertville on the beach and on the roads, also on private farm land.

"So far I've had drones chase my horses around the paddocks and while out riding. I have clients' horses here for training so it can be bit of a hassle if the horses get hurt by being chased from the drones.

"My usual bombproof horse that has been worked on a farm his whole life and used to all sorts of unusual things reared up and tried to fight a drone that came close enough I could have touched it.

"Drones are becoming a big safety issue as you don't need a licence or permit to drive one. There's not much anyone can do at the moment especially if you can't find the controllers so people like myself tend to take matters into our own hands when it comes to the safety of our clients and my own horses and stock."

While there were plenty of positive outcomes from drone use, they could be a "real danger" in the wrong hands.

After she posted her experience on Facebook, one user suggested people "shoot them out of the sky and stomp them to bits...huge invasion of safety".

Others also agreed with the sentiment, while some people recounted experiences when their safety had also been impacted by drones flying too close to horses.

A Federated Farmers spokeswoman said it was legal - under the Dangerous Dogs Act - for a farmer to shoot a dog worrying stock or poultry but this applied to only dogs, not drones.

"As far as we are aware there are no rules about shooting unmanned aerial drones."

A CAA spokesman added police would be involved if a drone was shot at.

Any dangerous drone activity should be reported on the CAA website, he said.

Hastings certified drone operator Tim Whittaker said had permission not been obtained for the drone operator to fly over McGhie's property then there was "no excuse" for the operators actions.

He recommended the incident be reported to the CAA because drone operators could "absolutely be nailed for that".

However, Whittaker added a bigger issue with amateur drone users was the sheer number of them.

"I've heard anecdotally, daily stories of people flying illegally.

"I don't think CAA are doing enough, I don't think they realise how big it is.

"What I see as the big issue is essentially CAA's role in education the public involve issuing a tiny bit of paper directing a new drone owner to a website to familiarise themselves with the rules.

"Except can you imagine a dad and son or daughter with a drone they have just bought from Harvey Norman wanting to even read that piece of paper?

"The first thing they will want to do is charge it up and fly the thing."
