Creating the props and puppets took 12 hours over three days, while filming took six hours. The film runs for 13 minutes.
Carter, who called in to the cinema on Wednesday to watch a check screening, said she is "stoked" with the end result.
She said there was a lot of excitment among the children about making a real film. "The kids took it and ran with it."
Her team involved David Clark, editor; Stephanie Fourie, a fine arts student and Lizzie Murray, who assisted with the workshop.
The screening includes a three-minute animated stop-motion "teaser" trailer called Bully of the Day.
The Time Machine will screen at Regent 3 in Masterton on September 23, 4.30pm for drinks and nibbles, 5pm screening.
