People who are not so fortunate are at the forefront of Richard's birthday wishes, specifically, the children and families of the Starship hospital.
Proceeds from his birthday bash at Baycourt are all going to the Starship Foundation.
Among the guests performing is virtuoso pianist Grant Winterburn and Tauranga blues and roots band Kokomo. Also joining Richard is long-time friend and well-known broadcaster Mark Sainsbury.
Award-winning Australian actor/singer Craig McLachlan, who played Frank N Furter in the 2014 revival of The Rocky Horror Show, is flying over from Australia to join the fun.
Supporting Starship children's hospital is a tradition for Richard who asked family and fans to donate to the hospital in lieu of a gift for his birthday.
"Richard O'Brien has been a wonderful supporter of Starship Foundation over the years and we are so honoured he has chosen to support us again by giving up his 75th birthday for Starship.
It's a brilliant concept, and one we hope will inspire others to jump on board and give up their own birthdays to help children, young people and their families from all over New Zealand," says Starship Foundation chief executive Brad Clark.
