The Trentham Sports Centre is an indoor artificial-turf practice area in Trentham Memorial Park, at 68A Barton Road, Upper Hutt. It is a registered charity run by a volunteer trust on behalf of Junior Cricket Upper Hutt Inc, which owns the building. All income from users goes back into maintaining the centre. The practice area is about 38 metres long and 11 metres wide, and retractable nets can divide it into three lanes. It is used for cricket, football, softball and baseball.
The Trust provides a cricket bowling machine, a softball pitching machine and the balls for them, six cricket wickets, two indoor football goals and a ball speed radar at the end of lane 2. Users bring their own other equipment. There is seating for spectators, a changing room, and CCTV monitoring of the centre. The bowling machine may not be operated by anyone under 16, and batters must wear helmets with face guards, pads and gloves. Regulation cricket balls must not be used in the machine.
