A spate of bikie-related drive-by shootings in the New South Wales Hunter region has triggered the formation of a new strike force to tackle gang-related violence.

A large number of gunshots were fired into a house and car in Chisholm, near the town of Maitland about 1:00am on Thursday.

Detective Superintendent Wayne Humphries said there have been six public shooting incidents and two Molotov cocktail attacks in the region since January.

"All of these matters relate to the behaviours of outlaw motorcycle gangs within this area … the Nomads and the Finks," he said.

"It is clear there is some type of dispute between these two groups.

"We have been actively investigating and operating on both groups."

Strike Force Danay has now been established to specifically tackle the violence in the Hunter region, and will work in tandem with the Strike Force Raptor, which specialises in investigating NSW's outlaw motorcycle gangs.

On Wednesday, police announced Strike Force Raptor had dismantled the Nomad's clubhouse in the Upper Hunter town of Muswellbrook after a raid last week which found a fully-functioning bar, as well as clubs, believed to be used as weapons.

This operation follows the dismantling of the Nomads clubhouse at Islington, Newcastle, in early February.

Both clubhouses were shut down for the illicit sale of alcohol under the Restricted Premises Act.

He said the cause of the feud was still unclear and none of shooting victims were cooperating with police.

"We believe there is no danger to the community in terms of randomness of attacks," he said.

"This is a targeted attack between two groups who are undertaking this criminality.

"They have a misguided code of silence and we've got to try and break that down."

Detective Superintendent Humphries encouraged anyone with more information to contact Crime Stoppers.
