If their record in Wellington in recent years is anything to go by, the All Blacks will be nervous heading into the decider against Ireland on Saturday.
Ireland levelled the series with the 23-12 victory over the All Blacks last weekend, their first win on Kiwi soil.
As Ireland hope to make more history this weekend, they will take solace in the All Blacks' shaky recent record in Wellington, where they've won only once in their last five matches.
Here's how the All Blacks' last five tests in Wellington played out:
The first test of the Ian Foster-Sam Cane All Blacks era got off to a nervous start.
After the All Blacks failed to kill the game off, Wallabies wing drew the game level at 13-all after 63 minutes.
James O'Connor then put Australia ahead with a 73rd minute penalty, before the All Blacks escaped with a draw on a typically wet and blustery Wellington day thanks to a 79th minute Jordie Barrett penalty.
The match would stretch nine minutes into added time and could easily have gone either way, before the referee called an end to the clash.
July 2019: All Blacks 16 Springboks 16
In a preview of the two sides' opening 2019 Rugby World Cup clash, the All Blacks and South Africa played out a 16-all draw in a tense Rugby Championship test.
Springboks replacement halfback Herschel Jantjies scored a try in the final minute of play to help his side snatch victory from the All Blacks.
Jack Goodhue scored the All Blacks' only try of the day, sparked by a sensational break from Beauden Barrett.
Handre Pollard slotted over three penalties for the visitors and held his nerve to convert Jantjies' try to even the scoring as the hooter sounded.
September 2018: All Blacks 34 Springboks 36
It was a different time, when the All Blacks losing to South Africa was still a shock.
The Springboks put in one of their best defensive performances as they hung on to a 36-34 victory.
The All Blacks played most of the rugby but couldn't break down the visitors in a final 20-minute onslaught.
The Lions levelled the series after a controversial victory in Wellington, which was notable for the sending off of Sonny Bill Williams after 55 minutes.
The All Blacks failed to score a try all game, with Beauden Barrett slotting over seven penalties, while Taulupe Faletau and Conor Murray tries for the Lions levelled the game at 21-21.
After Charlie Faumuiina was penalised for tackling Kyle Sinckler in the air, Owen Farrell stepped up and kicked the winning penalty for a famous win.
