Ireland emerged victorious from a chaotic game to claim their first win over the All Blacks in New Zealand and level their three-match series.
The All Blacks were permanently reduced to 14 men when Angus Ta’avao was shown red on 31 minutes in a bizarrely undisciplined first half in Dunedin. Andrew Porter scored a try in each half for the visitors, who led throughout.
The series will be decided in next week’s winner-takes-all meeting in Wellington.
Having never beaten New Zealand before 2016, Ireland has now won four of the last seven meetings between the sides – with their latest victory arguably the most emphatic example of the strides taken under Andy Farrell.
Their cause was aided by a violently off-colour New Zealand, whose disciplinary problems saw them twice temporarily reduced to 13 men in the first half, while they only posed an attacking threat in the final stages of each half.
Ireland will anticipate an enormous response next week but will fear nothing as they go in search of what would be a sensational series win.
At the end of an utterly chaotic first half, which took almost an hour to complete, the All Blacks were somehow just three points behind, which would have given the hosts a huge boost as they went into the shed.
Most of their problems were of their own making, as shocking indiscipline led to one red card and two yellows to give Ireland their best chance ever of winning in New Zealand.
At no point in the half did the visitors cash out their numerical advantage, however, all 10 points of their first-half came before any cards were issued.
As was the case in Auckland a week ago, Ireland jumped out of the net and this time got to the try line within three minutes as Porter crashed after a huge carry-up in the middle from Tadhag Birne.
It was a devastatingly accurate start from the Irish as the All Blacks struggled to find any sort of rhythm.
In 17 minutes he found himself down 14 as Leicester Fanganuku was sent into the bin to fly past Mack Hansen’s shoulder, avoiding the young Crusaders wing only red as his first contact was with Hansen’s chest.
Ireland continued to dominate and was only a meter from the line, only to come off with a try-saving interception for Beauden Barrett.
It looked like New Zealand were out of jail, but video replays showed Ofa Tu’ungfusi facing Gary Ringrose with the ball and the centre set to pick up an inside pass from Johnny Sexton.
Although Ringrose appeared to be the favourite to run clear for the try line, he was not dealt, referee Jaco Peiper considered that there were enough cover tacklers and therefore opted to reward the penalty attempt, but Tungfasi was not dealt. sent in.
