The 87-year-old was found lying on the floor of his Frank's Ham & Beef shop on Union Street at about 4.30pm on Monday 12 March 2007.
He'd been savagely bashed and later died in hospital.
Initially, detectives believed Mr Newbery had been the victim of a robbery-gone-wrong.
An inquest in 2012 delivered an open finding and failed to identify any suspects in the case.
Officers from Strike Force Rynan have renewed their appeal for help in solving the Mr Newbery's murder and are now not ruling out the incident could have been a deliberate attack on him.
The state government issued a $100,000 reward in October 2007 for information leading to the arrest and conviction of those responsible - to date no-one has come forward.
Anyone with information is being urged to contact Crime Stoppers on 1800 333 000.
