A $2 million re-development at Cullinane College is on track to be finished by Christmas.
The new buildings will house the school's wharenui, te reo Māori teaching space, performing arts space and recording studio.
Principal Kevin Shore said the new building would replicate what was already there, although in a different format.
"The old buildings date from the 1960s, but they met only 20 per cent of the current earthquake standards. Obviously that's not ideal.
"It will also be a more modern learning environment for our students."
