"It was pleasing to get a strong performance like that under my belt leading into this tournament. The reason you get performances like that is through hard work and I've worked extremely hard all year."
Carter was asked about how the noise might affect him and his team against the Pumas at a stadium in which the crowd are almost within touching distance of the players.
"It all blends into background noise," he said. "Having those rugby or football or rugby specific stadiums like this which we don't always get in New Zealand, can change the atmosphere a little bit. It can make it a better atmosphere to play in. I don't mind it, to be honest. It's not like you can hear individual people yelling out stuff. As a player it just turns into background noise.
"It's quite good to familiarise yourself with the stadium before game day," he said of the kickabout with Barrett. "Obviously there will be a few nerves this time tomorrow so to take in something new then could be quite challenging. To be here 24 hours before we're more relaxed and can learn more about the stadium. It could be as simple as the touchlines to the stand, just getting your bearings."
Coach Steve Hansen, meanwhile, sitting between the pair, was reluctant to talk about the performance of the match officials in the opening match between England and Fiji at Twickenham, a game which went for more than 100 minutes due to the constant stoppages and TMO referrals.
"People will form their own opinions - you only have to read what's being tweeted and what's been said," Hansen said. "There's no point in me jumping on it. They'll sort it out.
At the end of the day, it's obviously a new toy they are playing with, the [television technology] Hawk Eye, and people are a bit excited about it, but it will come back."
