Voting in the referendum is by post only and people must be enrolled by today to get voting papers, and they will need to be back with the Returning Officer by noon on December 17 to count.
The referendum is required under law after the Labour and Greens-led Keep Our Assets coalition secured 327,224 signatures in a petition this year.
People can check your enrolment details at www.elections.org.nz or phone 0800 36 76 56.
If you have moved house since you last updated your enrolment details, your papers will be sent to your previous address. In that case, you have two options: apply to have your mail redirected at New Zealand Post or online at www.changemyaddress.co.nz, or register to have a replacement voting paper sent to your new or temporary address at www.elections.org.nz.
