New Zealand has taken Secret Santa to the next level with thousands of people taking part in a nationwide Christmas gift exchange.
Twitter users began receiving gifts from their Secret Santas as part of a quirky nationwide social media campaign.
Prime Minister Jacinda Ardern was among the 3,623 other Kiwis registered for the Secret Santa campaign, which was run by the New Zealand Post.
Ms Ardern received a handmade Christmas tree decoration from her Secret Santa, opening her gift in a video posted to twitter.
"It's beautiful. It's my first Christmas decoration," Ms Ardern said.
"Thank you so much to my Secret Santa. This is really special."
Participants were encouraged to Twitter-sleuth their giftees to see what they liked before sending their presents to a central "Santa Storehouse" for distribution.
Some participants seemed to have gone well beyond the $10 suggested gift limit, with one woman posting with the hashtag #NZSecretSanta that she had received an iPad, apparently from telecommunications company Chorus.
But many participants did not plan on waiting for Christmas to open their packages, and took to Twitter to post photos and thank their anonymous gift giver.
