The Māori electoral option is a four-month period that occurs every four to six years, where some voters can choose to move between the general and Māori electoral rolls. It is the only time when Māori voters can change their roll choice. The last Māori electoral option was in 2018, and the next one is due to be in 2024. This timing means that without changes being made, Māori will be locked in to their roll choice for two general elections: the first in 2020, and then for the upcoming 2023 general election.
