Coming into the All Blacks camp has been a step up for debutant Waisake Naholo.
The Highlanders winger is one of two new caps in the All Blacks side to take on Argentina at AMI Christchurch on Friday.
Crusaders hooker, Codie Taylor, is the other newcomer and but he'll start on the bench.
Waisake Naholo says the All Blacks environment is more intense than what he's used to at the Highlanders.
"Coming in here you meet players you've only seen on TV or players that you idolise, you get to hang around them and learn from them, yea it's different."
Naholo says he's ready to pull on the black jersey.
"I am really, really excited about it, this week has been really different to what I've been through, I'm just really excited to get out there on the weekend."
Meanwhile starting halfback TJ Perenara will be hoping to recycle the ball quicker to his backs after the test against Samoa.
"We've got some of the best backs in the world and giving them the ball as fast as they can and giving them that little bit of extra space is going to be important and just controlling my side of the game, getting us into the right sort of positions, making the right decisions and executing my core role."
Coach Steve Hansen resisted making wholesale changes to the team who scraped to a 25-16 victory over Samoa despite the influx of 17 players from the Hurricanes and Highlanders, who missed the Apia game because of the Super Rugby final.
Naholo, centre Ma'a Nonu and halfback TJ Perenara were the only players from the Super Rugby final brought into the starting team for Friday's match.
World Player of the Year lock Brodie Retallick has also shifted from the bench into the run on side in place of Sam Whitelock.
"We have a lot of respect for Argentina and what they bring and understand that we will have to improve our game quite considerably from our Samoan effort," Hansen said.
"With that in mind, the selectors did not want to make too many changes."
"It's a fine balancing act between getting game time for those who need it, giving others the rest they may need, and giving ourselves an opportunity to see players and combinations in the heat of the test battle so we can make good selections going forward."
The Crusaders hooker Codie Taylor should also make his test debut off the bench.
Hansen said while the World Cup was now clearly in their sights, he wanted the team to focus on each of their three Rugby Championship clashes as they came up.
"There has been a lot of talk about the Rugby World Cup and so forth, but this test match is all about the here and now," he said.
"It's important that we get away to a really good start... as we will only be playing each other once this year and we only have this one home game."
"We will need to get points early if we are going to give ourselves a chance of winning the Championship."
