"We were so nervous," she said.
"Then we won after the first three games - so there was no pressure on the last two people to play."
Year 11 student Erin Wyllie said there were "so many people watching and yelling" but she was just trying to stay calm.
"It felt good that I didn't have to put pressure on the last two players."
Three of the players - Gen Kennerley, Grace Spencer and Erin Wyllie - then went on to win the transtasman tournament later that month, representing the junior national squad, going head-to-head with students from across Australia.
The trio played in Queensland alongside two other students from Takapuna Grammar and Marlborough Girls' College.
Wyllie, who started playing squash at the age of seven, said it felt "quite crazy" to be representing New Zealand overseas.
"It almost didn't feel like it was real," she said.
Mia Bowles said winning an offshore tournament "felt pretty amazing".
The team, who train between four to six times a week, all agreed they "put in a lot of time" and had made sacrifices when it came to their social lives to reach their level of success.
They also felt the school attracted top squash players, with Kayla saying the team's success would not waiver in the coming years.
"I am the only one leaving one next year - and the team is going to be the same for the next two years. So there are going to be some pretty good players for quite a while."
