Also wondering what might have been were Harvey Round Motors Ratana as they completed the regular season with a 27-17 win over Utiku at Memorial Park.
After a tight first half, a further five tries were scored in the second stanza, with Ratana halfback Kane Tamou getting a double.
Despite wins over Pirates, Border and McCarthy's Ruapehu this season, Ratana ultimately finished just three points adrift of Taihape in fifth place, which magnified their 18-15 loss on June 7 to Marist when they blew a 12-point lead, along with their large number of tight matches where they were unable to secure four-try bonus points.
At Marton Park, Wanganui Car Centre Kaierau were able to get themselves a home game in the consolation semifinals, beating Speirs Food Marton 41-20.
Kaierau were also awarded a penalty try amongst their five pointers, while Ace Malo had a good day with the boot by slotting seven kicks.
In the Senior championship, all three games had a bearing on the final makeup of the Top 4 and it was Power Farming (PN) Hunterville and Ruapehu who finished in the strongest positions.
Defending the Stihl Shop Wanganui Challenge Shield at home against a Marist Celtic team that upset them in Round 1, Hunterville held on for a 28-25 victory to retain the shield for another year, although in 2014 they did lose it to Ruapehu early in the season before regaining it from Tech later on.
Their loss consigned Celtic to the long trip up to Ohakune after Ruapehu completed three weeks of very consistent form to comprehensively polish off Border 40-7, who had been eyeing up fourth spot until the last fortnight.
That result meant Tech were safe for the semifinals no matter what their result, but they made sure of it by running up a 50-7 scoreline over Pirates, who have been outgunned after making it through to the championship group when the senior competition split after June 14.
In Senior consolation, Counties finished top of the table with a 24-8 win over Marist Buffalo's, setting up the semifinal between the same two teams as the Buffalo's were unable to climb past Taihape, who were on their bye week, into third spot.
Marton had to settle for second spot after their 72-0 mauling of bottom of the table Kaierau.
