Seven Freyberg High students want their new book Pio the Whio to be compulsory in the school curriculum.
The story book for tamariki was launched in Palmerston North by the students under their business moniker Thirteen7, and places them up against 30 schools in the region for this year's Young Enterprise Scheme (YES) awards.
The regional winner will then go through to the nationals in Wellington.
The book created in te reo Māori and English is a fully illustrated book that educates tamariki about the consequences that come with pollution of our environment.
