Ireland coach Andy Farrell has revealed their intent to "bring a bit of chaos" to create doubt within the All Blacks' minds in the series-decider in Wellington on Saturday.
New Zealand are on the verge of their first test-series defeat at home since 1994, after their historic loss to the Irish last week.
The tourists claimed their first-ever win over the All Blacks on Kiwi soil, prompting coach Ian Foster to ring the changes for the decider.
Meanwhile, Farrell has made just one change to his triumphant XV, with Bundee Aki starting over the injured Garry Ringrose.
Farrell signalled their intention of disrupting the All Blacks' gameplan, and hopes to create a sense of disbelief within the opposition players.
"We'll see whether there is that much improvement that's needed because we're in control as well as them," he said.
"They've got a plan but it's up to us to make sure we bring a bit of chaos to that plan. We've got to make sure that we put a bit of doubt in the All Blacks' minds as the game goes.
"Like every other game, because of our intention and accuracy and what we do, that's what we need to get over the line first and foremost.
"If one team is imposing their game on the opposition, then there's always that little bit of doubt that creeps in from both sides.
"I think the All Blacks over the years have been the world's best at being calm under pressure, staying on point and not letting things get to them," Farrell said. "But it's our job to make sure we push them to the limits of that."
Ireland have now won their last four of seven test matches against the All Blacks, dating back to 2016.
But Farrell is wary of a potential New Zealand backlash at Sky Stadium.
"It really doesn't get any better for us. We've all talked about playing against the All Blacks when their backs are against the wall and they've come off a loss. We know what history says about all that.
"But that's exactly where we want to be. We know they'll be hurting, we know that they bounce back unbelievably strong. We've played them enough times now to know what's coming.
"To have them in the last game before we break for another season, we expect them to be fired up and really wanting to prove a point to us and themselves.
"It couldn't be any better for us, to be able to deal with those types of situations, it's exactly where we want to be."
