The Prince of Wales and the Governor-General are offering 64 New Zealanders the chance to party with them at Government House when they both celebrate their birthdays in November.
Prince Charles turns 64 on November 14 during his visit to New Zealand with his wife, the Duchess of Cornwall. He shares his birthday with Sir Jerry Mateparae.
Other New Zealanders born on the same day can enter a ballot to win an invitation to the birthday bash.
And just so you know the Governor-General and Charles say the winners do not need to worry about taking presents.

Niels Holm, Official Secretary at Government House, said the birthday party was a wonderful opportunity for New Zealanders to meet Prince Charles and the Duchess of Cornwall, saying "we couldn't simply allow it to pass without marking it in a special Kiwi way".
"And what better way to mark the Prince's birthday than to invite New Zealanders from a wide range of backgrounds who are also celebrating their special day to join a most memorable party."
Sir Jerry Mateparae welcomed the initiative and said: "The Diamond Jubilee visit is a chance to recognise 60 years' of remarkable service to New Zealand by our Queen."
"That we also have the chance to welcome the Prince of Wales and celebrate with him and the Duchess on this special day is, if you'll excuse the pun, the icing on the cake!"
Applicants must be 18-years-old and older, and will have to present a copy of their passport or NZ driver's licence for validation and security checks.
Guests will have to meet their own travel and accommodation costs. Each winner will be able to bring one guest to celebrate.
Applications close at 5pm on October 12. The application form can be downloaded from the Government House website.
Meanwhile, while on her trip, Camilla will take part in an event with young fans of New Zealand author Lynley Dodd, who created the bestselling Hairy Maclary children's stories about a dog's adventures with his canine friends.
The couple's tour will start in Papua New Guinea, the Pacific island state off the north coast of Australia that Charles first visited as a teenager in 1966.
The royal couple then travel to Australia for a busy six-day programme. They will meet members of the Australian Defence Force and the emergency services as well as farmers and school children.
As well as the usual round of political, military and religious engagements, the royal couple will watch the Melbourne Cup, one of the world's biggest horse races.
The last leg of the trip will be in New Zealand from November 11-16, with the focus on agriculture, business and sport.
