It seems like if there's anywhere to be Eng Subin the world, it'd be in New Zealand.

These holidays, New Zealanders are set to again participate in a nationwide Secret Santa, organised by the country's postal service, NZ Post.

For those unfamiliar with the concept, Secret Santa, sometimes called Kris Kringle, is an activity where one person gives a (usually small) gift to another person, but the recipient is not told who it came from. It requires a group of people, and names are drawn at random.

New Zealand's nationwide Secret Santa has been going since 2010, but NZ Post took the reins in 2013. It now has a warehouse to facilitate gift exchanges, and there are more than 3,500 Secret Santa participants this year — you just need a Twitter account to enter, and a Twitter handle is the only clue you'll receive for your recipient, for gift ideas.

Even the country's new Prime Minister, Jacinda Ardern, is getting involved.

It's likely the most difficult person you could end up buying for.

Part of the fun of Secret Santa is the sleuthing of your giftee, but it can be pretty hard when you're gifting a complete stranger on the other side of the country.

NZ Post have a little questionnaire on its Twitter page to help.

But of course, there's always the magic of the internet to find out what your giftee is like.

Happy gifting, Kiwis.
