Only one other batsman reached double figures, Regan Fricker unbeaten on 14, while spinner Robbie Power took 2-20.
In reply, the visitors had it all sewn up in just 22 overs, as Andrew Penn (58 not out) carried his bat through the run chase, hitting five boundaries.
Although Penn lost three partners cheaply, Chris Sharrock then came in for an aggressive 45 in 33 balls, hitting four boundaries and two sixes, before being caught out with 13 runs required for victory. Simon Badger entered lower in the order than last weekend to help Penn tick them off.
It was Penn's second half-century in as many games.
Up the road in Paraparaumu, Marist were always going to struggle to hold off Kapiti Old Boys after they were bowled out for 166 in 42 overs.
This despite an outstanding innings of 91 not out in 116 balls from Mark Fraser, making up for his tough dismissal the weekend before, as he struck nine boundaries and swatted two sixes.
However, he was left stranded short of a deserved century as the rest of the batsmen folded, other than John McIlraith with a typically spirited 32 in 33 balls, including four boundaries.
Six Kapiti bowlers picked up wickets, with the pick of the bowlers being Zack Benton (3-16) and Andre Halbert (3-30), who in four overs took some punishment from Fraser but cleaned up the tail around him.
In reply, Kapiti had the winning runs in the 38th over as, despite Nick Harding (2-32) getting an early wicket, opener Daniel Franks (74 not out) carried his bat through the innings.
The in-form Halbert (45) came in to hit seven boundaries, and while Harding also got him to an edge behind, Ryan Hickey (28 not out) joined with Franks to wrap up proceedings.
In the other games, Levin Old Boys and Paraparaumu Medical Centre CC continue to occupy the top two spots on the table, courtesy of convincing home wins over Weraroa CC and Burger King Red Star respectively.
