Police believe fireworks may have caused the blaze that gutted the gymnasium at Wellington's Rongotai College early on Christmas morning.
The blaze tore through the building, causing the steel-framed roof to collapse and destroying around $500,000 worth of equipment.
Investigators are still trying to find out how the fire started
