"We're especially pleased that 16,694 voters in the 18-29 age group enrolled during August, but there are still a lot of people who aren't enrolled," chief electoral officer Alicia Wright said.
"You need to be enrolled to be able to vote and have your say this election, so if you're not on a roll already, get it sorted now," she said.
