While not a chanceless innings, his century set it up for Bevan Hunter (25), Kane Watkin (38) and Paul O'Callaghan (30no) to all hit out.
The bowlers suffered horribly with John McIlraith (1-80), Craig Thorpe (2-95) and Sam O'Leary (0-62) all going for plenty from their ten overs, where fortunately the long grass in the outfield prevented a number extra boundaries to further inflate the score.
Fraser Kinnerley (1-40) did his best to pin Tech down in the early stages, while captain Mark Fraser brought himself on to remove Lock and two of the tail enders to finish with a truly respectable 3-28 including two maidens.
Trying to mitigate the lack of fielding options, at one point Fraser got into a lengthy debate with Hunter when he was umpiring after initially calling a no ball for the number of players outside the circle.
Starting with only eight wickets in hand, it got no better for Marist as Tech's Trent Hemi picked up a couple of early scalps, leaving them at 113-5 after 19 overs.
Only Fraser pushed on doggedly, scoring 56 which included a towering six into the trees at the far end of the ground, before Dominic Lock returned the favour of the first innings by having him caught trying to hit over the top.
There just weren't as many scalps for the Tech bowlers to share, but O'Callaghan bagged 3-17 off his 6.5 overs, while Hemi was the next best with 2-20 from six.
A disappointed Fraser said university and Marist rugby commitments were still keeping a few players away, but Marist was truly the Premier team most suffering from the wider issue of not enough local depth among 20-30 year olds, as well as a lack of enthusiasm from youngsters.
"We're sort of relying on more school kids and they seem to not be interested in cricket.
"You don't know what people are getting up to these days. But not playing every Saturday, for those thinking about Central Districts [representative level], they're going to go downhill.
"We should hopefully come right, for December and January at least."
Down in Marton, it was another match where key players were like Atlas carrying their teams as Property Brokers United saw off Matt Burke Engineering Marton Saracens' chase by 47 runs.
Marton captain and Active Physio Wanganui coach Dominic Rayner would do well to ask five of club cricket's lesser players if they wouldn't mind doing a spot of farm work on Hawke Cup weekends so that United's Tom Lance could declare himself available.
To follow his 97 against Tech the previous Saturday, Lance batted through to 110 of United's 208-7 total and only he could dismiss himself hitting the wicket while attempting a pull shot.
By comparison the next highest for United was Mr Extras with 27, followed by Robbie Power's 15.
Rayner took 2-24 from his ten overs while Mark Jones was the pick of the Marton bowlers with his medium pacers, 3-29.
Marton could not haul in the gettable total as they slumped to 161 all out in the 48th over.
Continuing his captain's knock, Rayner fought through with 59, even sharing a 50-run partnership for the eighth wicket with Bryant Galpin, but there was no other support.
Gerard Hobbs had to leave Marton early but left his mark before he did - opening the bowling and finishing with 3-23 from his ten overs while Power took 2-27 off seven.
