As the All Blacks look to finish the unprecedented season of 2020 with a good enough win over Argentina to secure the Investec Tri Nations title in Newcastle on Saturday, they have been working on exercises designed by coach Ian Foster to ensure they don't let their discipline slip.
Consecutive losses to Australia and Argentina due to penalties conceded, especially within goal-kicking range, have put the acid on the side to lift themselves and to learn to turn the other cheek.
Experienced fullback and first five-eighths Beauden Barrett said discipline had been an issue for the All Blacks, but also for opponents, and the referees had been forced to make some big decisions.
It was up to the All Blacks to ensure they didn't give the referees anything to penalise them for, he said.
Assistant coach John Plumtree said plenty of pressure had been going on the discipline aspect in training with some innovation being applied.
"We've come a long way in that space and, definitely, a lot of the players have learnt more about that and just about controlling their emotions on the pitch," he said.
Barrett said while they worked hard without a Test last week, there was more incentive this week with a game at the end of it and they were keen to finish their season strongly and their year on a high.
"We've got an opportunity to win the competition. We clearly respect the opposition this weekend, that is Argentina.
"We have to go about our work and take it just one day at a time. There is plenty of edge around and we can't play the game too soon," he said.
Barrett said they had learnt a lot about the Argentina defensive plan from reviewing the Test and had been working on areas they would attempt to exploit on Saturday, he said.
They had seen opportunities during the review and were kicking themselves they hadn't seen them in the game.
"We're aware that there is opportunity and that's just about us executing it, and seeing it, so we're excited that we can break that wall down," he said.
"Whilst it felt like they gave us nothing, looking at the tape is always easy and as long as we learn from that and look to exploit it this weekend," he said.
Barrett said there was nothing wrong with the heart in the side.
"Our intent might not have been where it needed to be at times, but that is something we can learn from. There's no doubting our heart and our desire to win and to do the best in this black jersey," he said.
