With the current projections, Fuller said the school was expecting to reach about 230 pupils by the end of the year with ease.
"It's a beautiful day to celebrate the journey we've all been on to get here."
The primary school was catering for Years 1 to 6 pupils in the school zone this year, with Year 7s to be welcomed in 2020 and Year 8s in 2021.
Like any new school, the keyword was "foundation", with Fuller acknowledging all of the foundation board, teachers, parents and pupils.
The room lit up with pride as the children as young as five stood up to sing two waiata for the guests and parents.
Politicians at the opening included Tauranga MP Simon Bridges, National education spokeswoman Nikki Kaye, local Labour List MP Jan Tinetti and Bay of Plenty MP Todd Muller.
Bridges said he was thrilled that after the long journey to get the school up and running, they had finally got there.
Growth at The Lakes had been "massive" and Bridges said it was as if the "centre of gravity had moved to the area", including many "refugees from Auckland" who had come to their senses and moved to the "best city in New Zealand".
Figures released to the Bay of Plenty Times under the Official Information Act showed $18m was allocated in 2017 for the new school.
At the ceremony, a special taonga was unveiled for the school, which was a large stone uncovered from kumara pits on the school site.
Bridges was given the task to unveil the school plaque, which he said he always struggled to do "gracefully", however it went to plan and the school was declared officially open.
