A prominent Auckland school is being celebrated for its decision to build gender-neutral bathrooms.

Auckland Grammar is putting one of these bathrooms in its new block to accommodate for transgender students.

They don't currently have any trans students but the principal Tim O'Connor wants the school to be ready.

PPTA rainbow taskforce member Shawn Cooper says he applauds the school headmaster's foresight.

"This is a fantastic move by Grammar to prepare for what the future challenges may be for them."
