Down at Marton Park, Taihape moved back into the Top 4 after a no-frills 15-3 win over Speirs Food Marton, scoring a try in each half through front rowers Slade Hay-Horton and Rimu Wipaki.
Taihape's win coupled with Marist and Waverley Harvesting Border's losses creates a close jam from third through to sixth position, heading into the final three weeks of Round 1 which will be completed on May 17.
In the Tasman Tanning Senior competition, the Stihl Shop Wanganui Challenge Shield has its second owner in as many weeks as the Marist Buffalo's ended Ruapehu's short reign with a 29-15 win at Spriggens Park.
Defending champions Power Farming (PN) Hunterville continued their slump in form with a 17-13 defeat at home to Marist Celtic, leaving Hunterville in the rare position of sitting outside the Top 4.
The Downs Group Marton saw off Taihape 19-10 to currently move one point ahead of Tech at the cut-off point between the Senior championship and consolation grades, before the competition splits after June 14.
