Centre Kaveni Dabonaise scored a hat trick as five members of Border's in-form backline crossed the chalk, with fullback Nick Harding contributing 17 points.
Te Rangi Tapu McLeod scored two tries for Taihape, as well as adding a conversion.
Down at the Pa, visiting Settlers Honey Ngamatapouri accomplished their goal of a third-straight win to join the playoffs race with a 36-0 dismissal of wooden-spooners Harvey Round Motors Ratana.
Ngamatapouri scored three tries in each half, with Emosi Vucago getting a double, while first-five Te Tua Kemp added three conversions against his old club.
The South Taranaki club will have a tough conclusion to their debut round in Premier, taking on Border at the annual duck shooting night game on Friday, followed by a home match with Ruapehu on May 13.
In Senior rugby, Speirs Food Marton confirmed their hot favouritism for the title after they beat second-placed Black Bull Liquor Pirates 46-7 to lift the Stihl Shop Wanganui Challenge Shield at Spriggens Park.
It was their seventh straight win and puts them clear on top of the table, while Pirates are still clear of Hunterville in third spot, as they were on the bye.
Celtic missed the chance to move into the Top 4 after they were upset 10-5 by Counties in the other Spriggens Park game, with the visitors getting a small measure of payback for their narrow quarterfinal defeat last year.
Border leapfrogged Taihape into fourth spot after a 19-6 win over them at Dallison Park, while Ruapehu won a high scoring game at home against the Buffalo's, 56-26.
