Repolling in 28 polling stations across four districts in Manipur began on Friday amid tight security.
Voters were seen standing in queues before the polling stations to exercise their franchise which has been peaceful so far, an election commission official said.
Polling in Ukul, Tengnoupal, Kangpokpi and Senapati districts was held during the second phase of the assembly elections on March 8.
The repoll was ordered on Tuesday following electoral malpractices in these polling stations, the official said.
Repolling started at 7 am.
On Thursday, repoll was held in 34 polling stations in three districts in Manipur and 89 % voting was recorded.
