"I feel a little embarrassed trying to talk up this game and I don't know a lot about [the history of the cup]," Miller explained.
"[When I played for the Mason Cup] it was more about 'hey there's a trophy on the line and we want to win it', and to be honest we were playing Boys' High so whether there was a cup or not it was a grudge match. But, the cup was something nice that you got in your hands."
While Miller believes, from his time playing for the cup and coaching Kamo High, the cup has always had a strong meaning for players, he hopes the rugby public is able to fill the void around who PJ Mason is, or was.
"In the past it has just been there's a cup on the line, and it has actually meant something without people really knowing what it is, so maybe if people did know about him it would mean more."
Miller's call for rugby historians is echoed by his Boys' High School counterpart Ben Smith.
Smith, who is Boys' High's director of rugby, was originally sent onto the PJ Mason hunt after Sky TV asked him for information on Mr Mason for their commentators who will call next weekend's game between Kamo and Boys' High.
Since then, Smith has spoken to members from the Boys' High Old Boys' network and people from the rugby community. All of which have come up empty.
"There's no information, I mean we're local boys as well," said Smith, who also played for Kamo in the Mason Cup. "It's been there since 1968 and in that time 40 years has gone by, and we've lost [the history].
"There are a lot of people who have gone onto to pull on All Black jerseys who would have played for that cup, I find it extremely odd.
"I think it's very important to re-establish the history, it is grass roots stuff that needs to come back."
With Smith's searches proving fruitless, he came to the Northern Advocate to see if there was anything in the archives. However, that search, too, proved fruitless.
Smith, along with Miller and the Northern Advocate, is hoping an appeal to the rugby public might be able to shed some light on the mystery surrounding PJ Mason.
"It's an appeal to the Old Boys network of both schools," Smith explained. "A game like this [next week's Sky TV televised game] does need the significance that it deserves, because we've watched communities like Christchurch have to fight back from the adversities of the earthquakes, and we need to keep our history."
Miller agreed that knowing the history of the cup was important, adding that if he had of known the story behind PJ Mason he may have been more inspired.
"[Come match day next week], I'll probably be saying something similar like 'hey there's a cup on the line boys, the Mason Cup, and it's something we want to win'."
