However, the referee didn't appear to see the flag and, being 1989 when technology and professionalism wasn't what it is now, it looked like he was going to award the try.
But then a hero appeared: a ball boy pointed the flag out to the referee, and justice was served.
"I saw the touch judge's flag up and then I saw that New Zealand were scoring a try," the brave ball boy said after the game.
"And when they scored the try, I said to the touch judge 'this shouldn't happen, why don't you go on and tell him?' And the touch judge said 'no I can't do that'.
"Then one of the people in the ground told me to go on yourself."
The rest, as they say, is history.
