Border's tryscoring forwards hooker Cole Baldwin, No8 Ray Stark and standout flanker John Laurie hammered their opposition into easy turnovers and ran through traffic at will.
The most welcome recipient of the domination was the season's top points scorer Sikeli Ulukuta, who easily cut through despairing final tackle attempts for a hat-trick of tries, while getting plenty of goal-kicking practice to add 13 points.
At 58-0 with 20 minutes left, Border seemed likely to surpass McCarthy Ruapehu's 80-0 massacre of Utiku Old Boys on April 5.
But with the semifinals looming, Border coach Ross Williams subbed all his leading players, which allowed previous coach Peter Richardson going on for a halfback cameo.
Ulukuta and prop Kamipeli Latu were also sinbinned for professional fouls.
That let Marist get into rare attacking position for two late consolation tries.
Facing an anxious wait to see who they face and where in the semifinals, based on this coming weekend, Williams said their initial training sessions will be "light stuff" to let his players clear their heads after the pressure of the past month, before "ramping up" the following week.
"Realistically, it's not the physical thing.
"It's been a long season. The body is willing, but they're sore.
"Is the bye a hindrance?
"We'll tell you in two weeks."
They won't be relying on Marist pulling off a miracle against Pirates, with Marist coach Jason Hamlin admitting it will be a hard ask to get his relatively young side to lift themselves out of the quagmire.
"The boys are a bit down in the dumps on it.
"Our lack of depth has hurt us, resting guys with niggles, and the others have no experience. We're not quite there."
Other than kickoffs, only once in the entire first half did Marist get out of their own 50m zone after centre Ioesia Bolealeki managed a breakout, but Middleton just spread the ball to centre Sailoso Naqiso as they ran it 60m back and set up Ulukuta for his second try.
Ulukuta, Naqiso and double tryscoring fullback Ben Aiken often had to stop for bounced or lobbed passes, yet they still easily stepped through some woeful tackle attempts to scoot over.
Border were so tired from all the running that despite a 31-0 score they let Ulukuta take a penalty kick on halftime so they could get a breather.
It was getting embarrassing as Marist lock Tom Monaghan chased one second-half kickoff, only for it to bounce off his head.
Ulukuta completed his hat-trick after another Baldwin burst but was then binned for knocking the ball down, with Marist second five Matt Neilson burrowing over in a rare bright spot for the visitors.
Latu's departure allowed Marist No8 Ian Hawkes to add their second try after a series of quick taps, but an attempt to keep pushing for consolation points saw the ball spilled as Laurie swooped and dashed 70m untouched for a deserved five-pointer.
