But as they have displayed all season, Opaki are always in for the fight and will certainly start as favourites in this encounter.
Still in with a mathematical chance of snatching the title are Gladstone/Carterton, but they would need to wipe the floor against Masterton/Trinity in their match being played tonight and hope Opaki suffer a heavy defeat.
With Jono Hurley and Georgia Atkinson lining up for Masterton/Trinity that would seem a far-fetched notion, so it is likely Gladstone/Carterton will have to settle for the runners-up position and focus on finishing this part of the season on a high note.
The last time these two teams squared off Gladstone/Carterton performed a Houdini act to secure an unlikely 5-4 victory, and it would appear as though a similar result is in the offing here.
Masterton/Trinity have been the "Jekyll & Hyde" package of the competition and certainly have the personnel to rip any team apart on their day, though inconsistency has dogged their season.
For the record, Opaki have a four-point buffer over Gladstone/Carterton while Masterton/Trinity are a further four points adrift.
In the regional two competition, unbeaten Masterton 1 could face their stiffest test to date when they take on fellow contenders Martinborough at Martinborough.
Opaki 1 will start as favourites against the rapidly improving Gladstone while in other action Masterton 2 should have the measure of Trinity 2, and the local derby is a coin-flip between Opaki 2 and Opaki 3.
