Tuielu said all the players involved in the first XV at the time appreciated the impact Gordon and George had on them.
"They instilled in us the value of being loyal and commitment to one another and never to give up. We were very lucky to have them and that's why we've got a lot of time for them now, and in many ways they are the reason why we organised this [reunion].
"What they taught us was respect - to respect one another and respect our opponents."
While some of the team haven't seen one another since they left school, others are in regular contact.
Tuielu said the side had good role models provided by previous first XV teams and in turn wanted to create a legacy for future sides from the school.
The first time the reunion was thought of was at the funeral of Te Kowhai's mother last year.
After a muster this evening, there will be a bus tour and quiz tomorrow afternoon, the formal presentation of a framed commemorative jersey that will be hung in the school hall. The jersey commemorates Gordon's years as first XV coach and includes his nickname, Flash.
There will be a social event tomorrow evening open to all former students.
