The Black and Ambers are now 32 games unbeaten at their historic ground having avoided defeat in the last two Welsh Premiership seasons. But they had to come from behind to beat a spirited All Whites side who led for more than an hour through tries from full-back Aaron Mitchell and flanker Ben Lewis.
However Swansea failed to shake off the home side, who stayed in touch with tries from Will Kershaw-Naylor and Alex Walker. The game finally turned Newport's way when outside-half Aled Thomas, one of Newport's new recruits this summer, gave the Black and Ambers the lead seven minutes from time. Centre Richard Payne went over late on to seal the victory.
Defending champions Neath crashed to their first defeat of the season at Sardis Road where Pontypridd clung on for a 25-21 victory. Neath looked dead and buried before Gareth Morris stormed over in injury time to bring them back to within a point only for James Hook to scuff his conversion. Instead Ponty outside-half David Flanagan held his nerve to slot over a penalty deep into extra time.
Llanelli's Lee Byrne scored two first-half tries as the Scarlets brushed past Ebbw Vale 24-3 at Stradey Park.
