However since principal Mona Stewart came out from retirement to take over the reins of the school, its roll has increased to 37. This means activities like yesterday's, which keep children safe and improve their knowledge, are set to become more common.
Yesterday's event was organised by her son, Matau. He is a Health and Safety adviser for Z and was using his paid skilled volunteering leave to offer his expertise by helping the school be prepared for fire and other emergencies.
He prepared the students for yesterday's evacuation drill and taught them how to respond to different emergencies.
"This emergency preparedness is giving them the knowledge of what to do, not just at school, but at home," he said. "It's a life skill. Now, even the little ones know where to go and what to do."
The skill was not lost on Kupa, 8, who said he now knew he had to "get out" in a fire, and to leave everything behind even if he didn't want to.
This was echoed by 8-year-old's Lukqas and Dayton,who said they had also enjoyed hiding under their desks during the "earthquake".
Joining them at school yesterday were also members of the Fire Service, who were able to give tips on the pupils' evacuation and speak to them about the importance of fire safety and a home escape plan.
This meant yesterday's lesson would not stay at school. It was hoped the children would be able to take what they had learnt yesterday home, to educate their families about the best ways to be prepared.
As well as their new knowledge, each child was able to take home a smoke alarm - which had been bought with proceeds from Mr Stewart's fundraising at Z corporate offices.
After the evacuation, the principal said she was pleased with how the evacuation had gone and glad the school would have a plan in place for the future.
"At least we know they'll be safe, that they know where to go if something happens," she said. "You never know when the next earthquake might hit."
