Centre Enesu Seloti scored a double before halftime, with Lasa Ulukuta, Manulua Lafi, Brett Turner and Gordon Karaitiana adding second-half five-pointers.
With two weeks left in regular season, Ulukuta is looking the strong favourite for the MVP honours, opening up a four-point lead over Border fullback Fraser Middleton.
Middleton's Border team got the result they were looking for during what is never an easy trip in Marton, scoring four tries in the 29-3 win over the home side.
Again giving away a nervous start, Border turned around a 3-0 deficit with a try to in-form halfback Lindsay Horrocks.
Up by seven at halftime, Border ran in tries to Sailosi Naqiso, Lance Devane, Kampeli Latu as they look ahead to another tilt at Ruapehu's dominance, this time on home soil.
Despite successive heavy losses, Marton still have a chance to snatch fourth spot from Taihape, who sit with their potential game in hand with Kaierau.
While playing a home again, Marton is likely to find opposition Marist a stronger team than the side they thumped 27-5 at Spriggens Park in May.
In Senior championship rugby, Hunterville righted their sole wrong for season 2013 by holding off Celtic in the second half to win 20-10, this time successfully defending the Stihl Shop Wanganui Challenge Shield which shot through six pairs of hands after they originally lost it to Celtic in May.
Ruapehu had a harder challenge from Taihape than their Premier team faced, but still prevailed 20-13.
The consolation round sees Marton on top of the pack after their 24-17 win over Border.
