The school is one of eight around New Zealand selected to take part in the Visique ''Have A Sunny Day'' video competition, which illustrates the importance of wearing sunglasses and protecting young eyes.
And although they have started filming, no-one is saying what the video will be like.
''We're keeping our ideas for the video under wraps,'' teacher Judith Stanbridge said.
That is because the prize is worth having, and they do not want to leak their ideas to the other competing schools.
Visique Dunedin optometrist Peter Dick said the winning school would win $1000 and free sunglasses for the class that made the film.
Last month, he visited the school to explain why young people needed to protect their eyes from UV exposure in the playground, using electronic devices and in everyday life.
He revealed 80% of UV damage to the eyes was done before people turned 20.
Yesterday, all pupils and staff wore sunglasses to school, as the school's young film-makers started filming.
Mrs Stanbridge said pupils would be working hard over the next month to complete their video before the April 15 deadline.
