They then reached the target with six wickets down, led by a strong contribution from team newcomer Trey Bidois, who scored 71 from 54 balls.
It was a similar story in the 40 over game, as WCS bowled Parnell out for 193, with Bidois (3-38), Dinwiddie (2-22) and James Pennefather (2-29) sharing the spoils.
Set a challenging 4.8 runs-per-over target, WCS reached the promised land for another four wicket win, with the main contributions coming from Sam Sherriff (51), Ben Kelt (36) and Charles Greatbatch (21)
Touzel said the run chases were excellent against a competent bowling attack.
The WCS 1st XI will have six fixtures against fellow lower North Island cricket schools from February to April, as well as their annual trip to Christ's College in Canterbury in mid-March.
