The Bulls now seek to capitalise on their success with three home games in a row. They play Kaikohe this weekend, followed by must win matches against Takahiwai and the Falcons before away encounters against Otaua and Hora Hora.
Selkirk said Joey Paniora and Edwards were standouts as the Tigers swarmed seeking a late try but the Bulls defended like a team that were determined to win.
It was an unusual weekend for the competition with not one, but two games abandoned without a ball being played. A rare default by Hora Hora showed the lack of playing numbers available to the new club. They were well short of getting the numbers needed to make the long trip to Kaitaia to play the Falcons and were forced to make a late cancellation.
The other abandoned match between leaders Hikurangi and third-placed Hokianga wasn't played because the appointed referee failed to show up. Given the important nature of the game both sides failed to agree on a suitable replacement and following the competition guidelines both sides had to settle for a share of the points.
Rugby League Northland CEO Alex Smits appealed for former players to step up and sign up for the next refereeing course starting on Wednesday evening at Sport Northland. He said the area's dwindling refereeing numbers could be the biggest hurdle to growing the game in Northland.
Takahiwai leapfrogged Hokianga into third place in the competition, thanks to a superior points' differential, after a solid 30-10 away win over Otaua. The other completed matches saw City Knights keep their faint playoff hopes alive with a comfortable 34-6 win over Kaikohe, while Bay Slayers beat Marist 44-18.
