Owen Farrell, the English center who has Irish parentage, showed he had ice water in his veins with a 77th minute penalty to even the game 15-15.
Four penalties from Owen Farrell and one from Elliot Daly kept the All Blacks in check to secure a first tied series since 1955.
There was an air of anti-climax following the final whistle in Auckland, with team captains Sam Warburton and Kieran Read admitting their obvious disappointment at the result. An exhilarating finale saw a New Zealand penalty downgraded to a scrum but the double world champions were unable to convert late possession into a series-winning score as the Lions held firm heroically.
"After nights like this I can't believe the future of the Lions has come into any doubt to be honest".
"We all know what happened and we all know probably what should have happened but at the end of the day it's a game and as little kids we were taught to take the good with the bad", Hansen said. It was right in front and it would in all probability have been the last kick of the series - and possibly the series decider.
"So after that I might just go to the beach and put my feet up for a while".
The All Blacks' gamble in starting rookies Jordie Barrett and Laumape paid off in the first half, with both scoring tries as the hosts dominated.
But this time the full-back was in place to slide over for a score of his own and take some vital wind out of their foes' sails so close to half-time, with the missed conversion keeping the All Blacks 12-6 up at the interval. "It was a shot to nothing as they had already awarded the penalty".
Farrell was all but flawless in Wellington (after being shaky earlier in the tour), while Barrett missed three of his ten shots at goal.
The Lions tour of New Zealand began in ominous fashion with losses to the Highlanders and the Blues.
The penalty, had it stood, would have given Beauden Barrett a routine kick at goal to win both win the match and clinch the three-match series. At the same time, it is never nice to be on the end of a draw.
I didn't want a refereeing decision in the last minute to be the lasting memory of the series.
But the attention soon turned to referee Romain Poite's 77th-minute decision in which he first awarded a penalty to the All Blacks for offside but then changed his original decision on the advice of the assistant referees and Television Match Official.
"I said last night, as young people we were always taught to respect the referee and play to what he sees and that's what we'll do".style="text-align: center;"
