Fullback John Kilisi is the top Marton points scorer with 78 including a dozen tries.
Mid-fielder Eric Sagapolutele has scored eight tries with prop Isaac Greer and loose forward Stephen Kerehana collecting six each.
Hunterville, who reigned supreme with six titles in a row between 2009 and 2014, were finally beaten 28-7 by Ruapehu in the 2015 final and last winter finished third behind Ngamatapouri and Marton, being eliminated 29-17 by the hosts at Marton Park in the semifinals.
This year, Hunterville dropped two successive early matches - a shock 20-17 home game to Taihape for the Stihl Shop Wanganui Challenge Shield and then 25-19 away to Marton a week later.
Since then, there were second round Top Six defeats at the hands of Marton (30-3) and Celtic (34-13), but Hunterville avenged the Celtic loss with a close 11-9 semifinal victory on the same Spriggens Park field last weekend.
Fullback Leigham Harding has scored 124 points for Hunterville this year with the top try scorers being winger Matt Horton (nine) and first-five Scott Parkes and flanker George Gardiner (six each).
It is just the third time since the turn of the century that Marton has played in a senior final.
Pourewa (Hunterville and Marton combined) was beaten 34-11 by Marist in the 2000 final and Marton contested last season's final.
Marton won the Premier combined title in 1989 (21-12 vs Marist) and 1994 (38-15 vs Ohakune-Karioi) after losing 13-9 to Marist in the 1988 final.
Ruapehu beat Border 22-14 in the recent Senior Consolation final in Waverley to win the title for a second year following a 51-12 victory over Buffalos last season.
