Across the park, despite having their fair share of players who had not padded up in regular competition, Rangitikei gave Cullinane a tougher morning, raising 125-8 from their innings.
However, on the back of a Brett Cameron 69, the city school cruised to 126-1 in 16 overs.
Reliance on Cameron and his fellow top order players was near total for Cullinane in the final, but when their captain skied the ball for Joe Redpath to take a good catch, the writing was on the wall.
Adam Boult (36) and Raymond Teki (34) made the one noteworthy partnership as 103-6 was not likely to be enough. Caleb Martin (3-10) and Adam Gill (2-11) were the pick of the WHS bowlers.
Rangitikei handily won the playoff for 3rd/4th while Ruapehu, with Brendan Berquist providing some entertainment by slogging boundaries despite having not played since primary school.
