Andrews' fortunes, however, were about to take a turn for the worse, the Kawasaki seemingly hitting problems to fall into the chasing pack and reduce the front group to four.
Back at the front, having spent a few laps getting back on terms with his rival, Easton got the better of Ellison again to reassume the lead, Camier following later on in the lap with a clean pass on his team-mate at Lodge.
Now in pursuit of Easton with six laps of the race remaining, Camier immediately began to put pressure on the Scot. However, Easton's apparent superior straight line was negating Camier's strength in the bends, the Croft winner not putting a wheel wrong as he confidently kept the new runaway champion at bay.
Camier's persistence would be rewarded though when he out-braked Easton into Lodge, the 23-year-old succeeding in pulling Ellison through too before quickly putting on a sprint for the finish.
However, having rebuffed Ellison's pass with a move back into second almost immediately, Easton was not allowing Camier to pull away, signalling his intentions at the start of the final lap by overtaking at Old Hall.
Although Camier would slip back up the inside again, Easton would shadow him through the Cascades, Shell and Britten's to get good speed on the run down to Hizzy's. Pulling up alongside, Easton dived past into the lead, giving Camier no chance to respond.
Despite Camier's best efforts to get him back, Easton rounded Deer Leap to take a popular victory for the Hydrex outfit.
There was double joy for Shaun Muir's team too after Hill got himself up to third by mirroring his team-mate's pass on the final lap, this time over Ellison. Ellison had to settle for fourth, just 0.3secs from the winner.
Beyond the fight for victory, the battle for fifth went down to the chequered flag, Andrews' problems backing up a line of eight bikes. A superb display of defensive riding ensured he would allow through just one rider – Guintoli – to cross the line an important sixth.
Julien Da Costa followed his team-mate in seventh, ahead of Ian Lowry and Walker, while John Laverty completed the top ten on his Buildbase Kawasaki. Alastair Seeley had been on course for a possible top ten finish on his debut, only for him to crash heavily at Hizzy's with two laps remaining.
Others to miss out on a finish included Josh Brookes, who was up to second by turn two of the first start, only for a terminal mechanical problem to strike him almost as quickly.
