It was a huge undertaking to turn the comic into an animated feature film in the 1980s, he says, as there were no animators based in New Zealand and no opportunities for Government funding.
On top of that, Ball turned down Cox's idea to turn the comic into a movie but was later swayed, and the pair remain good friends.
John Barnett helped get the funding off the ground, and about 200 animators worked on the film in Australia, drawing every frame by hand.
Cox hopes the re-release will encourage parents and grandparents to show a new generation the iconic Kiwi movie.
"It think it's just as important now as it was then to enjoy the characters, the language and the jokes and, in some ways, to laugh at yourself," he says.
The film will screen at 14 Event Cinemas around the country for a limited two-week season, September 1 to 14.
