The Electoral Commission is beginning an enrolment drive to make sure people are enrolled for this year's local body elections.

"It's time to check you're enrolled, and that you're listed at the right address, so you're ready to vote in October's local elections," says Ross McPherson, enrolment and community engagement acting general manager.

"Over the next week, we'll be sending an enrolment update pack to everyone on the electoral roll. That's more than 3.5m packs.

"Check your details when you receive your pack. If they're correct, you're all set to vote. If anything needs changing, go to vote.nz to update your details online or make the changes on the form and send it back.

"If you don't get a pack by July 7, it means you're not enrolled or you need to update your address.

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

People can enrol or update their details online at vote.nz using their New Zealand driver licence, New Zealand passport or RealMe verified identity.

The local elections will be held in October for city, district, and regional councils.

The elections are run by local councils and are held by postal vote.

Voters need to be enrolled at the correct address to receive their voting papers in the mail.

"Councils make decisions that affect our daily lives on things like rates, rubbish collection, and public transport, so it's important that you're enrolled and ready to have your say this October."
