Scaracens' Bryant Galpin (5-18) tore through the school boys who managed 76 before being dismissed in 20 overs.
Beau Hourigan (25) and Nate Lewis (17) were the only Collegiate batsmen to score double figures.
At Tasman Tanning Victoria Park, 91 and more than a run a ball from Ross Kinnerley was the only resistance St Johns Tech put up in their pursuit of Paraparaumu's 232.
The defending champion Paraparaumu batted out their 50 overs amassing 232 and were able to create mini-partnerships for each wicket.
Fraser Kinnerley picked up 3-38 of his 10 overs but Tech were unable to find the back-to-back wickets they probably needed to give themselves a chance.
In response Ross Kinnerley's innings was a shining light and the only batsmen to score double figures as he hit 10 fours and two sixes on his way to 91 off 85.
Tech were 67-2 at one point in the chase but from there lost regular wickets to be all out for 160 in the 40th over.
Meanwhile, Marist's trip to Weka Park in Raumati Beach was short-lived as they were demolished by Kapiti Old Boys by eight wickets in 13 overs.
The Whanganui side could only manage 105 despite a half-century from Mark Fraser.
Marist were going strong at 78-3 approaching the 20th over before a collapse ended their innings just 12 overs later with the only 27 more runs on the board.
Kapiti bowler Carter Andrews (4-24) proved a handful for Marist.
In Levin, Weraroa cruised in their chase of Levin Old Boys' 215 all out clinching a five-wicket in with fours overs to spare thanks to openers Matthew Good (97) and Adam Simonsen (72) who put on a 151-run opening stand.
