"The elderly community in Rotorua is expected to rise by 34 per cent in the next 10 years, that is a New Zealand statistic. Parksyde is being proactive in meeting the current and expected need."
Mr Monty said the centre was finding a balance between using the room for patrons' activities and commercial use, in a bid to be self-sustainable.
The room can also host conferences with a commercial PA system and on-site catering facilities.
Rotorua Energy Charitable Trust chairman Grahame Hall said the trust provided $100,000 towards the room's development.
"In 2000 this became a Rotorua Trust Millennium Project and we made sure it had some continuity with tremendous success. This centre is used every single day," Mr Hall said.
"This used to be a storage area and has been redeveloped into more useable space."
Parksyde was designed as a community entertainment centre for the elderly.
Run without a bar or gaming facilities, it operates as an event centre, including a dining room, library and activities room as well as the meeting room.
