Toby Ricketts and Marianna Young will be married by the leader of the New Zealand Church of the Flying Spaghetti Monster, and attendees - bride and groom included - will be in full pirate regalia.
Pastafarians believe in an airborne noodle god, wear colanders on their heads and practice a gentle form of piracy.
The couple are recent converts to the Church of the Flying Spaghetti Monster, and the bride-to-be Ms Young said a conventional marriage and all the traditions that went along with it did not appeal.
"So this offered an opportunity to do something different that fitted for us."
The Church of the Flying Spaghetti Monster started as a parody to protest the teaching of creationism in Kansas public schools.
And now look at how it has evolved.
And to be honest, is it really any more ridiculous than any of the other religions that it was created to mock?
