Sometime between Wednesday night and Thursday morning, the Shooters, Fishers and Farmers Party (SFF) candidate's corflutes were set on fire on the back of his truck. 

The vehicle had been parked overnight in a well-lit area of Durham Street, near KFC, as a way to build his profile during the election campaign.

While the damage was minor, Mr May said the situation could have been much worse.

"If it had of gone up in flames, it could have burnt trees - it would have been a real mess," he said.

"It's lucky that it didn't take hold, because I've got my potato boxes on the back [of the truck] and those potato boxes, because they're so dry, they would have gone up in flames so quickly. 

"It just would have engulfed the truck and engulfed the trees around the truck."

Mr May didn't initially report the incident to police, saying it had slipped his mind due to pre-polling commitments, but he did get in contact with police on Friday afternoon and now plans to make a formal report. 

The fire was not the first time in this election the candidate has had issues with his promotional material.

Around 50 of his corflutes have been stolen around the electorate, leading Mr May to believe that the thefts and arson were "dirty tactics" carried out by supporters of an opposing political party. 

"It must be. I know I'm a threat and it seems that I'm being targetted," he said.

He went on to say that if anyone thought it was acceptable to light his signage on fire, they needed to "take a good, hard look at themselves". 

The incidents will not deter him from his campaign, but rather motivate him further. 

"It makes me even more determined, because this is illegal activity," Mr May said.

"It makes me more determined to push forward and push harder, because I believe in what I'm doing.

"I'm doing this for the good of the people in the community and I believe that we're in a place where we really need change, and to have a situation with new, fresh blood, where there is someone on the ground listening all the time, to take those concerns of the Bathurst electorate into Sydney." 

Voting for the NSW election will be held on Saturday, March 23.

There are six candidates vying for the seat of Bathurst.
