"And, I guess, this offers an opportunity to share resources, reduce costs and to share membership ... and is probably more sustainable."
According to architectural drawings, the state-of-the-art facility will include a two-storey building with a reception, golf shop, large social areas and lounges, plus an indoor batting area. Two smaller buildings for changing rooms are also included in the plans.
The facility would be erected between the cricket ground and hockey turfs at Smallbone Park.
Mr Mortimore said costs were not yet known for the new facility, nor had any start dates been set for construction.
He said their focus at this stage was simply setting up a shared trust so they could move on from there with gaining funding.
"The three sports groups are in the process of creating a trust - a legal entity to take the process forward," he said.
Rotorua Lakes Council owns the grounds at Smallbone Park and have allocated $300,000 to $350,000 towards building public toilets in the area, in its long-term plan.
Councillor Charles Sturt, who heads the council's sport and recreation portfolio, said the toilets could be built in conjunction with this project and he liked the idea of a joint facility.
Springfield Golf Club president Brent Frew said the club had approved the idea in principle and would be willing to move its clubrooms down the road if the project went ahead.
"We quite like the idea, but we would definitely have to change the course a bit."
