Clearly shaken by the costly losses Ireland were further behind when Barrett added a controversial try for New Zealand when it looked like he didn't ground the ball, but he was given the benefit of the doubt by the TMO.
Ireland ended their 111-year wait for a maiden victory over the All Blacks with the 40-29 win in Chicago on November 5, and are now primed for a furious backlash in Dublin on Saturday.
The average odds remain with Ireland placed at six to one for victory, with the All Blacks one to nine on to win.
Despite being the two-time world champions, Hansen's side have clearly been rattled by what Ireland inflicted upon them two weeks ago.
"Warrior effort from Ireland".
Ireland, whose only change from Chicago has Sean O'Brien replacing the injured Jordi Murphy at openside flanker, is expecting a "Blacklash".
In the backs Israel Dagg, Malakai Fekitoa, Anton Lienert-Brown come in while in the pack there's a return for the vastly experienced second row pair of Samuel Whitelock and Brodie Retallick. Andrew Trimble, 13. Jared Payne, 12. Cian Healy, 18. Finlay Bealham, 19.
"Josh Van der Flier was excellent, he had a big presence and slotted in really well".
Sexton stormed down the tunnel with a hamstring injury and on came Paddy Jackson. Robbie Henshaw's match winning try was scored following pressure on Julian Savea from a Zebo kick. Beauden Barrett, 9. Aaron Smith; 8.
First-team regulars such as Ben Smith, Julian Savea, Beauden Barrett and Dane Coles will all reappear at the Aviva Stadium, as will skipper Kieran Read. Sam Whitelock and Brodie Retallick will return to do all of the dirty work.
Replacements: 16. Codie Taylor, 17.
The All Blacks' reaction to a loss can be gauged by the seven years since any one team beat them back to back.
Meyer, Harbaugh have a chance to recharge a rivalry

ON a day where pretty much everything that could have gone wrong for Ireland did, they were denied back-to-back wins over a cynical New Zealand.
"I felt we deserved to get our nose in front, the players rolled their sleeves up and hung in and managed to protect the lead we had". I don't think there is going to be anything massively different.
"We're at about 6-1, not that we're allowed to indulge in that".
"We'll need a performance that's up there with the best we've ever produced in an Ireland shirt".
"I think Steve Hansen's just being modest".
"I thought we didn't get the rub of the green on the (two) calls but that's something that can be a distraction, it's not for us to make those decisions".
"But I wouldn't suggest that Steve Hansen become a bookmaker".
Both sides go into the clash on the back of straight-forward Test wins, having cruised past Canada and Gli Azzurri respectively last weekend.
"They'll be full of confidence and committed to delivering on their home patch".
"We just want to try to focus on our own performance, try to use Chicago as a reference point", Schmidt said.
"We were tested a lot in that game. When we look at the tapes I'm sure some of those are avoidable", Hansen said of the penalties.
