The opening game of the four-Test November tour pits the two nations against each other in one of the most challenging rivalries in the All Blacks' recent history.
Robertson said the selection was the best for this game, with an emphasis on the finishing side.
Centre Quinn Tupaea and No8 Peter Lakai played well in the second Bledisloe Cup Test and earned their opportunity to start again.
"Peter is very good both sides of the ball and with the ball in hand. He defends well and is good on the ground. He's a power athlete and good at all aspects, so he's a good Test footballer."
The history between the sides, especially their last meeting in Chicago when Ireland beat the All Blacks for the first time, was ever present, with the number of Irish fans in the city. The key for the All Blacks will be learning from the lessons of the last game.
Robertson didn't expect the fact that Ireland coach Andy Farrell hasn't coached the side since the Six Nations due to his British & Irish Lions commitment would hinder them.
"They know who they are, they've been around long enough. They've got a lot of cohesion and have played together a lot. They'll be pretty clear on how they want to play. They'll be up for it."
He said having a strong ball carrier at second five-eighths in Stuart McCloskey was a surprise in Ireland's selection.
"They've got a few dings and a few players not available but he's a big ball carrier and will add to the team. Sometimes guys get the occasion and rise to it and I'm sure he will."
Robertson did not subscribe to the view that the All Blacks' wins in their last two Tests against Ireland meant they had their number.
"I don't think you can say we have the edge over them. These games are really close. We expect that this weekend as well. It will be a tight, physical match that will come down to skill set or effort.
"You expect the best of them, and we've got to be on our best.
Both sides have named strong benches, and Robertson said that was necessary for the All Blacks because their finishing is critical.
"We've got some good combinations and guys that can cover different positions, it's important."
The field for the game will be narrower than usual for Test matches, but Robertson said they had prepared for that.
One of the contests in the game is that between former Chiefs wing James Lowe and new All Blacks wing Leroy Carter, who plays for the Chiefs.
"James has made a great career for himself in Ireland, and we've got a fledgling wing who's going pretty good after coming from Sevens. They've got their own storylines so it'll be a great head-to-head."
Wing Caleb Clarke is grateful to be back in the side after missing the last Test due to injury.
"Watching Leicester [Fainga'anuku] in that last game in Perth inspired me to lift my game seeing what he does, how he is on the field, and I'm looking forward to it."
There were some new challenges in the Irish side with a new back-three combination. They had talked with Jordie Barrett, after his season in Ireland, to get some intelligence on their opponents.
He is expecting to have plenty of opportunities to indulge his enjoyment in fielding box kicks from Ireland's inside backs.
"It's going to be a big part of this game and this year you can see how much winning the aerial battle swings momentum in games."
Lakai said that, apart from the fact that they are meeting in the United States, it is his first time playing Ireland, and he is looking forward to playing at Soldier Field.
"It's an exciting opportunity to have our chance to rewrite history. I was in school the last time the team played here. Speaking to a couple of the boys who were a part of that squad, they are looking forward to righting a few wrongs."
But that wasn't preoccupying their preparations.
"We're taking our opportunity again. We've had a look at the past but it hasn't been our main focus."
