Member Lauren Brant, in New Zealand to promote the film, said it was a new twist on the show and something different for fans.
"It's a really special cinematic experience for parents and children. There are parts where we call on the children to get up and dance and there's a lot of singing as well. It's not your typical movie."
Brant said it was an exciting time for the show, given those children who grew up with the original cast were now in their early twenties.
"Hi-5 is now close to 14 years old. It's been the same format this whole time and they haven't really involved the audience before because obviously children grow up.
"We just thought that this was a really great way to involve the audience...We wanted to show the parents and the children just how much passion and energy there is behind Hi-5."
Brant said the team was planning a tour around New Zealand - where they have a huge fan base - at the end of the year.
"It'll be really cool... I've never had the chance to tour in New Zealand so I can't wait for that...I was here for the Rugby World Cup and it was amazing."
Tickets to the film are on sale now at Hoyts Cinemas and website.
