Over 3000 people have signed up, including New Zealand's Prime Minister, Jacinda Ardern.
“So you may have noticed I don't tweet especially often (I just lurk) but as a ridiculous lover of Christmas, I couldn't miss the chance to join the @nzsecretsanta movement,” Ardern wrote on Twitter.
The giant gift-giving operation started in 2010 after a man who calls himself a giant pumpkin grower. However, NZPost has since taken over the sorting process.
Although registration is now closed, you can follow NZSecretSanta and stay up-to-date for next year.
