He came up with the idea after being asked by others for help with their maths, including pupils at Pt England School, where he had given a talk at a careers day.
"I had to go to school myself, so I made Tristan's Learning Hub, which is me using videos to teach people," he told the Herald.
Tristan, who gave a presentation at a TEDx event in Auckland last year, said the videos used "in-depth vertical learning". At present there are around 30 videos on maths, but Tristan has plans to add English and science videos.
