A yellow card didn't help Marist's chances either, and with an overlap to exploit from an attacking scrum, Clare fed Alekesio Vakarorogo in the midfield to dash through the gap and hold off his chasers to score.
Lost possession by Marist trying to come out of their own half saw Border swiftly transfer the ball to the far sideline for reserve Neihana Parkes to add his name to the sheet at 29-3.
But thankfully the scoreline didn't blow out further, as Marist finished with the last try when following a quick tap, No8 Marius Joseph took the ball and dived through a gap to score.
Border will now host Ngamatapouri for the annual duck shooting night game on Friday, while Marist must steel themselves for the derby with Wanganui Car Centre Kaierau.
In the Senior competition, the Country group is proving a 'murderers row' of tough matches, as all three games finished as close thrillers in the race to get in the Top 3 to join the championship group.
Having started from behind the blocks due to defaulting their opening game, Harvey Round Motors Ratana withstood a second half comeback from Bennett's Taihape to hold on 19-15 in the Pa.
The Stihl Shop Wanganui Challenge Shield is proving an absolute talisman for Speirs Food Marton, who after two seasons at the lower end of Senior have shocked last year's dominant champions Kelso Hunterville, coming back from eight points down at halftime to win 31-27 in Hunterville's own backyard.
Having lost to Marton last weekend, Utiku Old Boys picked themselves back up for the trip to Ohakune, beating McCarthy's Transport Ruapehu 24-19.
In the Town group, Gemini Pepper Construction Kaierau is the only remaining unbeaten team, taking centre stage with their Premier club mates on their bye to run out 40-10 winners over Ali Arc Logistics–DNA Kennels Marist Celtic at the Country Club.
Black Bull Liquor Pirates recovered from losing to Celtic in their first game to running rampant over Border at Spriggens Park in a 73-0 shutout.
At McNab Domain, home side McCrea Scanning Counties also picked up an important bonus point in their 42-7 win over Marist Buffalo's 42-7.
