The team beat Marlborough by just one run to bring home the silverware and cap off a good week of competitive cricket.
Batting first, Mid Canterbury scored 148 in the plate final, before being bowled out in the 38th over of the 40 over match.
Top scorers were Patrick McHugh on 39 and Blake Robinson with 27. George Fulton followed up his 21 runs with the bat to take 5-20 off his eight overs.
Day one of the five-day tournament did not start well for Mid Canterbury, with their first T20 game against Southland Country abandoned and the second game resulting in a defeat against Marlborough.
On day two, they upset a Dunedin team in the 20-over encounter with three balls to spare, but lost a second game to Nelson by 29 runs. Day three resulted in wins over Buller and Otago Country.
Mid Canterbury finished 4th equal with five other teams after the grading rounds, but a lower net run rate put them in the bottom division of the play-offs.
Playing in the semi-final of the Neville Hoskin Plate against West Coast, the Mid Canterbury boys scored 385-5 from their 40 overs and went on to comfortably win the match by a huge 330 run margin.
Blake Robinson retired on 84, Tyler Maher hit 78 off just 36 balls, George Fulton picked up a half century and Hanroux Wessels took 4-10 from his 4.4 overs.
The Mid Canterbury team was coached by Kathryn Clark and Rosie Robinson was the team manager.
