Nigeria’s election commission has postponed the West African nation’s March 11 gubernatorial election, an official announced late Wednesday, citing logistics challenges.

The election for new governors for 28 of Nigeria’s 36 states will now be held on March 18. The move will allow more time for voting machines used in last month’s presidential and legislative elections to be reconfigured and deployed for the upcoming vote, said Festus Okoye, a spokesman for Nigeria’s Independent National Electoral Commission, in a statement.

The gubernatorial vote is part of Nigeria’s general elections for four-year single terms for major political positions, including last month’s presidential vote won by the ruling party’s Bola Tinubu. That outcome is being contested by the opposition.

Ahead of the gubernatorial election, a local court on Wednesday approved the electoral body’s request to reset the Bimodal Voter Accreditation System, or BVAS machines — part of new technologies heavily used this year in Nigeria elections to make them more transparent.
