People who didn't get an enrolment update pack in the mail earlier this week need to enrol or update their details.

The local elections are on their way and New Zealanders are being asked to check they’re enrolled and ready to vote.

National Manager of Enrolment and Community Engagement for the Electoral Commission Mandy Bohté said more than three million enrolment packs were sent starting at the end of last month.

She said if you didn't get a pack by last Monday (July 8), it means you're not enrolled or need to update your address.

"And if you get a pack that’s not addressed to anyone at your house, please send it back.”

For those who did get a pack in the pail, Ms Bohté said to check your details were correct so you don’t miss out on voting in the October local elections.

“If we’ve got the right details for you, you don’t need to do anything more. If anything needs updating, make the changes and send them back to us straight away.

Enrolling or updating your details is easy - go online at vote.nz, call 0800 36 76 56, or go into any PostShop.

The local elections are held by postal vote and people need to be enrolled at the right address to receive their voting papers in the mail. 

“Local councils and health boards make decisions on things like rates, parking, rubbish, parks and health services, so it’s important that you’re enrolled and ready to have your say,” Ms Bohté said.
