Before being invited to tonight's test, she had been planning just to be at the Viaduct Harbour to watch the opening celebrations and then go home to watch the game on television.
"I think I will be the envy of everyone in the community when they find out I'll be going to watch our boys.
"In Tonga, rugby is like a second religion and everyone is just mad about the game and the players. I think they are even more crazy than supporters for the All Blacks."
This week, about 7000 supporters turned up at Auckland Airport to welcome the Tongan team, 'Ikale Tahi.
Mrs Edwards said she had been exercising quite a bit more in the past week "to get match fit" just in case the car is parked quite some distance from Eden Park and she has to walk.
"My legs aren't as strong as they used to be, but I think they're ready to take me to the game."
But unlike 1969, when she felt "more Tongan than Kiwi", her loyalties are split after spending 48 years of her life here.
Although she will be dressed in Tongan colours tonight, Mrs Edwards will be bringing both the Tongan and All Black supporters flags with her.
"From the sipi tau to the haka, I am just going to enjoy every minute and every second of the game."
However, when pressed on which team she hopes will win the cup, she said: "I love my boys, but New Zealand's my home now. I'm backing the All Blacks to go all the way."
