Subsequently, in 1959, this ward was split into Punggol SMC and Tampines SMC. The present-day Hougang, Punggol and Sengkang were hived off as Punggol SMC while Tampines SMC took on significant portions of Ulu Bedok SMC to become one of the larger wards in eastern Singapore. Thus, Tampines SMC was made up of present-day Bedok (except Kampong Chai Chee which is part of the Kampong Kembangan SMC), Pasir Ris, Simei, Tampines. It remained thus until 1968 when Bedok was largely transferred to Kampong Chai Chee SMC.
From 1968, no significant changes were made to the SMC until 1984 when Simei and part of Tampines (which is south of Tampines Avenue 2) formed the new Changkat SMC due to the growing population in the fast-development in Tampines New Town. From 1984 to 1988, this ward then only consisted of present-day Tampines and Pasir Ris. The ward only contain the residents committees in Tampines that is north of Tampines Avenue 2.
As Tampines New Town continued to grow, it was subsumed into the Tampines Group Representation Constituency in 1988 which was the first election in which the Group Representation Constituency system was used. The fast-growing Tampines had 60,084 voters; and it was necessary to split into three.
Note : Elections Department Singapore do not include rejected votes for calculation of candidate's vote share. Hence, the total of all candidates' vote share will be 100%.
