The Citadel Cafe in Whanganui's Castlecliff has turned into a post office for the Christmas season, but it is only accepting mail for a very famous personality.
Cafe owners Roxi Douglas and Malcolm Whitlock say it's all about good Christmas cheer and keeping the wonder of Christmas alive.
Small children can write letters to Santa and post them in Santa's postbox at the Citadel.
According to Whitlock, Santa says every letter will get a reply.
"We are encouraging anyone in the area with kids to come into the Citadel, write a little letter to Santa and we will ensure that it gets there to the North Pole," says Whitlock.
