The match between Northern Wairoa and Takahiwai in Dargaville takes centre stage in the Whangarei and Districts Rugby League on Saturday.
Both are well-placed to make the play-offs, in fourth and fifth place respectively, but neither can afford a loss, with the pressure on them likely to provide a spectacular contest.
Leaders and defending champions Hikurangi face a tough test away at Otaua but, like Moerewa in second place, have already booked their semifinal spot.
Moerewa can still miss out on second place, however, and so won't be taking Marist's challenge lightly when the Whangarei side visit Simson Park.
With just three rounds to go after this week's games, there are a number of important encounters as the race for the two remaining playoff places intensifies.
