Rangiora High School has opened a new building that creates an open space the size of 27 classrooms.
The $15.5 million facility is the latest in a string of so-called "modern learning environments" being rolled out in schools.
It includes break-out rooms, laboratories and a communal hangout area, and brings 500 students under one roof.
Deputy principal Brian Hays said it allows teachers and students to work collaboratively.
He said it had been designed to reduce the noise coming from any one area so students would not be distracted from their studies.
