Acting president Roger Neilson, who has taken over for Kerry Ridgway, said the extra time will allow the club to get a handle on the whole situation.
The club announced their decision to delay discussions due to "a lot of talk about it around the town," said another committee member.
Laird Park, with around 40 members, has supported the idea of merger since Wanganui East first raised it, although president Judy Titter said they can carry on without it.
Ridgway previously said the amalgamation would be "right down the middle" and both clubs had to be satisfied they would not be kicked out of Laird Park by WBC after a move.
"[The Wanganui East property] could fit about eight houses, we are told, so it must be worth a bit of money.
"With that money and support from community grants, we are confident our plans for an indoor complex can go ahead for the benefit of the sport in Whanganui."
However, club life member Barry Stevens said the sale of the 5000sqm property would not bring in enough money to build indoor bowling greens.
"If, after moving to Laird Park BC, the indoor complex was found to be uneconomical, the Wanganui East BC would have moved from a two-green club to another two-green club, and moved to a council-owned property from a property completely owned by the Wanganui East BC.
"Why should the Wanganui East BC move and risk everything by investing heavily in another bowling club with the present situation of membership declining significantly throughout New Zealand?"
