"It's been one part of the school that we haven't been really strong at. That bond between the past and the present we haven't done very well."
Old Boys' Association chairman Barry Rosenberg said the inductees were a great start to the new initiative and the association planned on making it an annual event.
"These four people have excelled and really done well."
Reuben Lowe said he was pleased to be at the dinner representing his brother.
"It's a pretty big honour for George, I think he would have been delighted."
Mr Robertson, who played 34 All Blacks test matches, said he was very humbled to have been one of the first people inducted into the wall of fame.
"It came quite out of the blue. I didn't really expect it and I'm very happy that they chose me."
Mr Hickson's response to being invited into the wall of fame was feeling "proud and privileged".
"It was a surprise, it feels special. It's a fine school and the current [principal] appears to be ... enhancing their tradition."
