After a break of one season, the competition was re-introduced last year leading to the Mount's win.
In other early afternoon games at Boord Park today Central Indians play Cadets with Te Puke facing Greerton.
Lake Taupo CC make their season entrance in the 3pm second round after sitting out the bye in round one, where they will square off with Tauranga Boys' College.
The Taupo team found out about the realities of Baywide premier club cricket in their inaugural season 12 months ago.
But with some quality new recruits and a season of Baywide battles in their scorebook, the team from the middle of the North Island are expected to be competitive this season.
Greerton and Cadets will both want to lay down the challenge to the other sides when they meet in round two, with Te Puke and Mount Maunganui rounding out opening day.
