"High enrolment numbers, which has been the case for many elections."
However, that leaves 3 per cent possibly not enrolled - and the commission wants them to have their chance to vote.
"Make sure your details are correct now it means that you'll be sent more information about voting closer to election day, and that you'll be able to vote more easily on the day," says Mr Wicks.
People who do not receive their enrolment update pack by Friday will need to complete a new enrolment form.
People can enrol or update their details online at www.elections.org.nz, or get a form by free texting their name and address to 3676, calling 0800 36 76 56 or by visiting any PostShop.
They can also get information at www.facebook.com/ivotenz.
"We can't say it strongly enough the only way to vote in this year's General Election is to be enrolled, so get ready for it now," said Mr Wicks.
