Gurias now advance to the second round of the elimination finals this weekend.
Gurias got off to a flyer, dominating the first half with powerful centre and man of the match, Alex Max scoring a double, before Muruks clawed their way back into the contest, only to fall short by 2 points.
After their heartbreaking 22-12 loss to Muruks without head coach Francis Ray, back in round 14, the East New Britain men took to the Santos National Football stadium with a plan to tame Muruks in an early surge.
