It's that time of year again when Santa's elves are gearing up to receive letters to Santa - with a little help from New Zealand Post.

Every year New Zealand Post receives tens of thousands of letters from children with their Christmas wish lists to deliver to Santa.

New Zealand Post spokesperson Tina Morgan says sitting down and writing a letter to Santa and putting it in the post is a Christmas tradition for many families.

'Messages can be sent to Santa online too, and this year we've set up a new interactive website for kids to create and decorate their own digital postcard for Santa,” she says.

'Whether you're writing a traditional letter or sending a digital postcard, remember to include your name, address and age.

'Write to Santa and see what you get back!”

The address for letters, no stamp required, is:

Santa Claus

Santa's Workshop

North Pole 0001

Letters and digital postcards need to be sent in by December 4 to receive a personalised response in the mail from Santa.
