Rangitikei College will no longer ask parents to pay any fees for Year 9 students, including to take part in sports.
The fees will be removed from the start of 2019 and the school hopes it will result in more of its youngest students taking up sports.
Rangitikei College principal Tony Booker said the school would no longer ask for three different types of fees from parents.
They included the voluntary school fees, subject fees that have a "take home" component where students take projects home, and sports fees.
"We're very conscious of the burden school and sports fees place on our families.
