Newbridge opened up a five-point lead at the top of Division 1A when they beat their nearest early season rivals Enniscorthy 29-14 at home in Rosetown last Saturday night.
Winger Padraig Mahon, out-half Harry Murphy, prop forward Grant Wattleworth and scrum-half Ryan Jones were the home side's try scorers.
Coolmine made the short trip over the M50 to Westmanstown for a local derby clash with Garda and returned home with full points following a 32-22 success, making third place their own.
Monkstown also continued their solid start to the season and are a point further back on nine points, after they eked out a tough 17-13 victory at home over Skerries.
In the remaining game, Dundalk picked up their first win of the season when they beat visitors Tullamore 16-9 at Mill Road.
Division 1B is a much tighter affair as Tullow, Co Carlow and Cill Dara are all on eight points.
Tullow won 22-17 in Portlaoise, and Co Carlow posted a 15-11 home victory against Longford.
An injury time try by No8 Damian Broughall gave Cill Dara a 24-22 win over visitors Clondalkin. Wicklow got off the mark with a 13-6 home success against Ashbourne, whose failure to pick up a losing bonus point condemns them to the bottom of the pile -- for now.
Malahide are the early pacesetters in Division 2A with a maximum 10 points following their 45-0 victory in Ferbane against the West Offaly Lions. On Sunday they welcome the team just a point behind them, Kilkenny. The Noresiders picked up a four-try bonus point when they won 27-14 at Clane. They are pursued by Portarlington, who beat Roscrea 18-12 last week and on Sunday travel to the West Offaly Lions.
New Ross beat visitors North Kildare 19-10 last week.
Athy, Mullingar and Railway Union are the early leaders in Division 2B.
Tallaght, with a win and a draw, are the leaders in Division 3.
