More than 23,300 Māori have opted to change roll types or have enrolled to vote.
The 2018 Māori Electoral Option ran from April 3 to August 2 and gave all enrolled voters of Māori descent the choice to be on the Māori or general roll.
A total 52.4 per cent of Māori voters were on the Māori roll and 47.6 per cent were on the general roll, compared with 52.8 per cent and 47.2 per cent at the start of the Option period.
There have been net increases of 1200 on the Māori roll and 4015 on the general roll.
Enrolment and community engagement national manager Mandy Bohté said about 95 per cent of Māori voters chose to stay on the roll they were already on.
