Assistant coach John Plumtree said the laws were in place for player safety reasons. Coaches were always talking about body height and doing the right thing by targeting the right areas for contact.
But sometimes under pressure players got that wrong as had happened at the weekend.
Lock Sam Whitelock, who made his 100th Test start in the 22-24 loss, said absorbing changed interpretations of laws affecting all parts of the game was the same. It required going back to the start, breaking everything down, walking through the changes initially and then building the skill slowly.
Working with the coaches allowed players to break old habits by putting in hard over time to the point where it became an instinct in the player's armoury.
"When that happens, it's really rewarding to review your game, or even in the game, know that you've improved on that skill that you've been working on for the last week or two, or sometimes even longer," he said.
Plumtree said the management had pulled apart their game from the weekend. There had been things they got wrong, and they had been working on that ahead of playing Argentina on Saturday.
"It's just been correcting little parts of our game that we know if we execute we are going to create more opportunities to score tries and right now we're just not nailing a few of those little roles," he said.
The changes made for the Test had still seen a good side put out, but the changes in combinations resulted in a loss of rhythm yet, it was within two points of winning the Test.
"We're looking to build again and with new opposition we'll carry on," he said.
Plumtree wouldn't say what the approach to selection would be for the game but said loosehead prop Joe Moody would be available for consideration after his injury. Nepo Laulala would join the side after his paternity leave.
There had been a heavy workload carried by some players who had appeared in four Tests in five weeks, but Plumtree said there were no concerns with overload and the players had been responding well to the demands of the series.
Having different opposition for the first time in their campaign provided a different focus and Whitelock said it was refreshing to prepare for a new opponent.
Argentina hadn't played a lot of rugby recently, so there wasn't a lot of material to watch on them, but they had played them often enough in the past to remind them of traits to their game.
"It has been refreshing working out how they're going to play how we're going to try and stop it but also how we're going to impose our game against them," he said.
