The Nationals leader was dobbed in to Crime Stoppers by a member of the public in his home town of Armidale on Monday morning, after he was spotted without a face mask while paying for petrol after filling up at the bowser.
Police say they checked the service station's CCTV and issued a $A200 ($NZ214) fine to a 54-year-old man for breaching an order under the New South Wales Public Health Act.
The State Emergency Operations Controller, Deputy Commissioner Gary Worboys, said it was just one of 34 Covid-19 infringement notices issued on Monday - with 16 of them infringements for failing to wear a fitted face covering.
"Police were alerted to that. They took some action. That person was apologetic and co-operative with police and an infringement notice was issued," he told reporters on Tuesday.
On the NSW mid-north coast, a couple is facing assault charges after they allegedly started a fight after refusing to check in to a restaurant on Monday evening.

The man punched the owner, leaving him with facial injuries and a suspected broken nose, police say.
The women allegedly bit a bystander who tried to intervene. He has bruising and bleeding to his bicep.
