Hamilton's wet weather on Tuesday ensured the All Blacks were able to prepare for the eventuality of rain lasting through until the weekend.
Assistant coach Jason Ryan said there was at least one benefit from the rain: "Training in the rain helps you prepare for a game in the rain."
Adjusting to the wet meant catching the ball more on the chest, not giving passes that are unlikely to stick, and playing the game closer than usual.
Having wrapped up the series in Wellington, Ryan said Hamilton will give the management the chance to have a look at a few players who haven't been used already.
"Everyone that's had their opportunity of training, whether or not they've been called into the squad with injury replacements, or they've been training cover, have been outstanding for us."
Speaking to the performance of the front row, Ryan said tighthead prop Fletcher Newell had continued to show the form he demonstrated in Super Rugby Pacific, especially in the finals.
"He's had a consistent run of games which has set up his Test season and has got a lot of confidence."
Ollie Norris has shown the benefits of his change from loose forward play to prop.
"He had to change his whole body, and he's done that in a bit of a slow build in the last couple of years, and we put a bit of work into that space for him, too. We know he's aerobically got a big capacity, he moves well across the park, and he's dynamic.
"He's starting to understand the fundamentals and the dark arts of scrummaging, and we've got a lot of confidence in him, and he's done well in the couple of appearances he's had."
Ryan hinted at continuing evolution in the All Blacks' innovation approaches. Innovation is always possible, and they couldn't afford to get too comfortable performing the same things.
"We're having a crack at a few things but we are going to do simple things well too."
All teams are trying different things, and opponents are all doing their analysis.
"You've got to prepare for different pictures and it can change late. That's given the boys a bit of confidence in that sort of thing that they can execute and put a bit of work into it and have it come off."
Wing Sevu Reece said he had recovered from the head injury that he suffered in the first moments of the first Test and which kept him out of last weekend's Test.
Reece said he is enjoying the speed at which the team is attempting to play, and that trainer Nic Gill's approach has helped them.
"The way he trains us sets us up really well to suit the type of game we want to play."
Saturday's Test would be a chance for the All Blacks to make a statement about their 2025 season, and they are keen to make it a clean sweep of the French.
But they are also aware that the French threat remains.
"They will have nothing to lose mindset and we are expecting anything and everything from them. They'll throw everything at us. All the boys are wired for every like this. We know how the French play, they won't go away."
