Rowley clouted three sixes and 11 fours in his punishing knock and dragged his side through to a competitive total of 224 for five.
He had some solid support from Corey Blair, who added 37 in a stand of 111 for the fifth wicket.
Cromwell’s Finn Farquharson was threatening with the ball. He picked up two for 29 and Sukhdev Singh’s one for 16 from eight overs was an impressive effort.
Singh made a big contribution with the bat, as well. He scored 58 from 51 deliveries and combined with Sam Pimm in a cracking second-wicket partnership of 93. Pimm reached 87 from 96.
The pair had Cromwell on course but the innings stalled when their partnership was broken.
Rowley (two for 31) nabbed Singh’s wicket and Scott Mitchell (three for 48) also helped restrict Cromwell to 215 for nine.
Maniototo eked out a modest total of 120 against Wakatipu in Oturehua but was good enough to defend it.
James Laurent top-scored with 55 and Duncan Elliott starred with four for 37. Cameron Ryall had stood out for Wakatipu with five for 33. Not a bad effort but still part of a losing effort. His team crashed to be all out for 96.
