Tech head to Donnelly Park to meet Levin in the battle for fourth spot, while Marton could also creep into the playoffs if they can somehow upset Paraparaumu at Kena Kena Park, while hoping Weraroa and Levin also lose.
Marton swept the board against their fellow Whanganui teams with three victories, but have lost all their matches against the Horowhenua-Kapiti clubs.
Tech was the only Whanganui team to make the semifinals last year, barely scrapping into fourth spot, but then pulled out two tremendous upsets over Weraroa and Levin to win the inaugural title.
In the other game today, winless Marist host Kapiti at Victoria Park.
Points after six rounds
United 22, Paraparaumu 21, Weraroa 18, Levin 15, Tech 14, Marton 14, Kapiti 3, Marist 2.
