Acting principal Virginia Shortland said the work done by the two companies, all at no cost to the school, was very much appreciated.
Everyone was aware of the schedules of big businesses, and was grateful for the time and effort that had been freely given.
"God bless you," she said, adding that fewer than half of the school's 36 pupils would be able to swim a length of the pool without stopping.
"This will be an awesome asset for the school and the community," she said.
The children made no secret of their gratitude either. Pane Terewi said she had been at the school for four years, the last three without a pool (although a para pool had been set up over the last couple of years).
"Now you've fixed it and we can use it. Even my little sisters can learn to swim," she said.
Khalan Clyde, a pupil there for seven years, said the pool was now in the best shape it had ever been, "thanks to you guys."
"We don't have flash things or state of the art buildings, and the swimming pool is important to us," he added.
The formalities over, Ms Shortland announced that it was now "game on, time for fun (in the pool) and a feed."
The pool restoration project also had the support of Water Safety New Zealand's Save Our School Pool campaign.
It had been one of a dozen in the Far North, and more than 130 around the country that had been at risk of closing before the SOSP took up the cudgels, Water Safety New Zealand's Wendy Pannett said, adding that 156 school pools had closed nationwide in the past six years.
