Yesterday at Springvale, Berridge and co-organiser KJ Allen were supervising preparations for the three courts inside the building, as well as across the way, to accommodate the 35 teams.
"We're going down to Jubilee [Stadium] and created a fourth court," said Berridge.
"We picked up portable hoops from Arena Manawatu and we're laying the floor down today."
Wanganui Girls College was briefly considered as the venue for the fourth court, but Berridge said there was better viewing capacity to have the matchups in the neighbouring building.
As well as Premier, there will be some good matchups in the Men's A grade.
The 2011 champions Trentham, from Wellington, will meet 2013's champions OBC, as they are drawn in the same pool, at 4pm today.
Games start today and tomorrow at 9am and carry on until the last matchups at 6pm.
Labour Day Monday will be finals day across the three grades, starting at 10am.
The Men's Premier semifinals will be side by side on Courts 1-2 at 12pm, with the final on Court 1 at 3pm.
