The group have put together a new community centre concept, which they will discuss at the meeting.
The concept was designed by the local architects, and people from the town who have experience in the building sector.
It has an estimated cost of $2.9m -- less than half the estimated cost of the Waihinga Centre.
Mr Freeth, who will chair tonight's meeting, said the new concept would be "a practical, affordable and attractive alternative".
He said the new design was not a plan but "an example or demonstration about what [the centre] could be".
"We are putting up the concept to help get a proper discussion going -- a discussion that involves the whole community," he said. "We want to show the community and the council that there are other options."
Mr Freeth said a lot of money and time had gone into the proposed Waihinga Centre -- a design that was now looking "very uncertain".
Late last year the SWDC rejected a targeted rate which would see ratepayers pick up the $6.4m project's remaining $1.3m balance.
He said the new concept was an environmentally friendly design and would be more affordable to ratepayers.
There would be "half-a-dozen" speakers at the meeting and councillors had been invited to attend, Mr Freeth said.
