About 11.30pm Wednesday two men entered a licenced premises on Fullerton Street, understood to be the The Boatrowers Hotel, armed with what's believed to be a rifle and a tomahawk.

The two men threatened patrons and staff. A 40-year-old man received a small laceration to the face during the robbery.

One of the offenders demanded cash from a staff member before the pair fled the scene in a vehicle.

The 40-year-old man was treated at the scene by paramedics; no one else was injured.

Later in the night emergency services were called to a car fire at Pitt Street Reserve, Stockton.

"On arrival crews found a car totally involved in fire and quickly got to work wearing breathing apparatus to protect them from smoke and other contaminants," a statement from Fire and Rescue NSW Stockton crews said.

"It was later revealed that the car was suspected to be involved in an armed robbery.

"The car was extinguished and then handed over to NSW Police Force for further investigation."

Officers from Newcastle City Police District have since established two crime scenes.

Police are now appealing for anyone with information or anyone who may have noticed any suspicious activity in the area at that time to come forward.
