"Never in a million years could I have thought this day would come," Lowe said.
"Since I was a kid I dreamt of being an All Black, man. That's just a very Kiwi thing to do. But I gave up that dream. I wasn't quite good enough when I was at my best.
"But to be able to come over here and put in a performance against the best team in the world, they're the standard-bearers, and words can't describe what it was like to hear my country's national anthem and to stand in front of the haka. It's a childhood dream."
On the whole experience, the Kiwi told RTE: "It was awesome, it's been a big week.
"We backed up the way we played against Japan. It was good rugby, the way the game should be played. We put in a performance against the world's best and came out on top. It's sinking in. You don't get to play against New Zealand very often.
"I have never played against New Zealand [before]. It's up there.
"There were a few key moments that determined the outcome of the game. I'll cherish the win."
An emotional Lowe also got to spend a few tender moments after the full-time whistle with his old pals from back home.
"I spent a lot of time with a lot of those boys, some of my best friends, people I've lived with, who I seriously admire in terms of who they are as people, what they represent," Lowe told RTE.
"I've got to stand there and have a good old chinwag with a lot of the boys.
"It's a game of rugby at the end of the day. We're best mates, I've got best mates on both side of the fence. They were happy for me, I was happy for them but it's rugby at the end of the day."
