They were the top side defensively as well, conceding just under 17 points a week.
Their big strength lies in the backline. Marshalled by Northland halves combination Matty Markwick and Peter Breen, they've struck fear into most teams they've come up against.
OBM are coming off a dominant semifinal performance where they comfortably accounted for Hora Hora 64-17.
However, Mid Northern will be quietly confident. After a bumpy end to the round-robin stage, Mid Northern hit their straps in the semifinals against a determined Waipu outfit to come out muddy 24-10 victors.
Led by instrumental hooker Jordan Olsen, Mid Northern have proven their big game mettle.
While OBM have led the statistics on attack and defence, Mid Northern have been no slouches.
They've averaged 28 points while conceding only 20. More importantly, they've struck a bit of form at the right time.
The weather outlook isn't the best for the match, with showers expected in the morning, though they should clear before kick off.
Poorer weather may play into Mid Northern's hands as they've proved in two consecutive semifinals that bad conditions are certainly not a hindrance for them.
However, no matter what the conditions are like, both sides will be primed to etch their names on the trophy.
Meanwhile, the curtain-raiser will be just as exciting as Kamo look to reverse their fortunes from 2016 with a win over OBM.
OBM grabbed a 22-13 victory last season to complete one half of the club title double.
Previous matches between the two foes have been tight with their last four encounters being decided by less than nine points.
