Mr Stewart said Cossie Club members agreed a merger would be the club's best chance of long-term survival and Services & Citizens was approached.
"After our meeting we gave them some views on how it would work and we're waiting to hear back," said Mr Stewart.
"Now the ball's in their court."
Wairarapa Citizens & Services president Bill Hey said it had asked the Cosmopolitan club to put forward a detailed proposal, which his club had since received.
The proposal would be put to the Citizens & Services committee next Tuesday, at its monthly meeting, he said.
"It will go to committee members for a decision and we'll make a call at the meeting as to how we will respond to the Cossie club," Mr Hey said.
Any major decisions would be made at his club's annual meeting, which was coming up.
"Personally, I would like to see both clubs survive in their own right," he said.
"Contrary to what some people are saying, there is enough room for two clubs in this town."
