Sitting on 23 points and 22 points respectively, Old Boys Marist and Eastern United are within reach of an upset series win, but will need other results to go their way.
Missing the first round, Awanui put on a solid showing to make the round two championship final versus Massey.
Going down 31-14 in that fixture, Awanui were made to settle for second, but their impressive form - which included a 31-10 win over table-toppers Hikurangi (who beat Onerahi 71-0 in pool play) in the semifinals - showed they could have been on top of the standings had they contested the opening round in Dargaville.
Failing to fire in the first two rounds were, Kamo, Sharks, Mid Western and Whangarei Boys' High School.
Winning the championship final in round one and two of the Northland Club Sevens Series, Massey have claimed top honours with their back-to-back championship finals appearances, however, due to being an Auckland club they are ineligible for competition points.
