Two years after their maiden triumph over the All Blacks in Chicago, Joe Schmidt's side treated the Aviva Stadium crowd to a slice of glorious history on Saturday.
The All Blacks may be top of the rankings but according to their head coach, Steve Hansen, Ireland have overtaken them and become the best team in the world.
Ireland's entire November series has been building up to the All Blacks clash, with the opening fixtures against Italy and Argentina becoming nearly like warm-up games for head coach Joe Schmidt. Physicality and intensity wins test matches.
Ireland defended for their lives in the second half and shut out the All Blacks, with the visitors tryless for the first time against a northern hemisphere nation since the 1995 clash with France. The absence of Conor Murray for Ireland is huge.
It was telling that Beauden Barrett opted successfully for the posts rather than the corner with his first opportunity in range, an option Sexton turned down nearly immediately after the visitors gave away their sixth penalty in just over 20 minutes.
New Zealand native Bundee Aki was involved in the build-up, finding Jacob Stockdale on the wing who chipped the ball over the top before charging through to finish.
Barrett quickly levelled the scoring again, this time with an effortless drop goal from distance, but Ireland continued to put the pressure on with 22-year-old lock James Ryan once more hugely impressive all over the park.
"Ireland are a hard team to beat at the Aviva these days so when the All Blacks come into town everyone is going to pay attention", O'Driscoll told ESPN. "And when we get those chances to get the ball back we do that".
New Zealand this year swept the home series against France, won another Rugby Championship, and overcame the English at Twickenham last weekend by blanking them for the last hour in the rain.
I had visions of 2013 as they made their way up the pitch but I thought we kept our discipline really well and stayed in the system towards the end.
"I think the last few times we have played Ireland have been good Test matches".
"We've played in some big games before and we know it's about the process; getting our details right in the early part of the week so that we focus on playing and implementing that detail".
"They defended really well, we actually couldn't really break them down tonight so we'll learn from that".
