Curtis has plenty of experience in performing to others, as an actor in New Zealand and Hollywood films and through various other platforms.
Curtis told the Rotorua Daily Post when he was about 16 he did competitive break-dancing.
From there, he went on to do competitive rock 'n' roll when he was about 17 or 18.
Curtis said he and his partner won the nationals for senior rock 'n' roll twice in a row in the late 1980s.
The year before, in the juniors, he came second, he said.
He also did kapa haka at school for a couple of years when he was a teenager, attending a number of competitions.
He also performed kapa haka with Ngati Rongomai at a regionals competition about two years ago.
He said he was looking forward to Saturday's event, and to relaxing and enjoying himself.
"It's a fundraiser for fun, to raise awareness and help the hospice. That's the real kaupapa there: the hospice."
Curtis said the hospice helped a lot of families in need, from the elderly to young children.
The hospice was an important part of the community, as "you can never be prepared for what life throws at you", he said.
"When you don't need it it's out of mind, but when you need it it's crucial.
"I've been to hospice a couple of times supporting people and they've always done great work."
