FBC News reports Supervisor of Elections, Mohammed Saneem said this was done to meet the need of voters and in some cases, their safety.
He said FEO staff were unable to reach a pre-poll venue in Vanua Levu due to a flooded river and they will have to wait until the water subsides to cross the bridge.
He added in another case, schedules were moved to accommodate students, who are sitting their external examinations.
The SOE added any changes made to pre-poll schedules are updated to the general public as well as political party registered officers.
