The building has been built and retrofitted to the latest updated Nepal building code.
Nepalese Association Bay of Plenty president Ramesh Gurung said the school had reopened 15 days after the first quake but, two days later, another quake hit the school again.
Mr Gurung said the school's 204 pupils ranged in age from 5 to 14. While the rebuild was under way, the children were being taught in temporary shelters, built with tin and wood.
He said the Bay of Plenty community had reacted positively and generously to the Nepalis' plight and the commitment towards the fundraising programme by the Nepalese students living locally was commendable.
The school is in a remote area and Mr Gurung said the association's vice-president,Kumar Limbu, experienced this first hand when he visited Nepal to inspect the work.
"He believes the walk upwards is better than going to the gym."
Mr Gurung said the rebuild was a project that would enrich the lives of many future students who, without this project, would not have much of a future in education.
"Our well-wishers, supporters and most of all people and the community of Bay of Plenty, thank you from the bottom of our hearts," he said. "It was through the funding of the Bay of Plenty community. Everyone was generous, so we wanted to let everyone know what happened with the money."
The association had $7000 remaining from the funds raised and Mr Gurung said they were considering what to do with the money. It would likely be used for classroom equipment like computers.
The association aimed to visit the project site soon.
