The clock is ticking on the second referendum on the New Zealand flag, and the Electoral Commission is reminding voters to make sure they have their say.

"You need to make sure your voting paper is completed and back in the post before voting closes," said chief electoral officer Robert Peden.

"If you haven't received your voting paper yet, contact us urgently on 0800 36 76 56 so that we can check your enrolment and, if you're enrolled, issue you a replacement paper."

Voters should complete their voting paper by ticking the box next to their choice, put it in the return envelope provided, and drop it into a New Zealand Post postbox by Monday 21 March.


"We encourage people to get their return envelope into a postbox by next Monday, March 21" Mr Peden said.

"That way you can be sure it'll reach us in time to be counted."
