The selection of Chiefs midfielders Ngatai, who played against Samoa, and Seta Tamanivaulu is a signpost to the future with Conrad Smith and Ma'a Nonu out of the picture. However sevens recruit Sonny Bill Williams (another Chiefs man) having decided not to return to rugby league, there is another major long term option available.
Dixon had to be picked after a storming year or so for the Highlanders, a tough and physical loose forward who has the grunt and attitude for the highest level. Liam Squire is another robust loose forward who has been part of the Tasman success story.
But so much focus will be on McKenzie, who is still very much a work in progress. Selector Grant Fox said McKenzie is brave and "makes things happen".
He wouldn't elaborate on the work ons, but said: "This will help him grow his game. It's not if he is going to be an All bLack but when".
Tu'ungafasi can play both sides of the scrum - the All Blacks would have needed six props otherwise.
All Blacks Head Coach Steve Hansen said: "Many people, including our opponents, may be thinking we're vulnerable and are rebuilding. However, we don't have that mindset. We, as selectors, are very confident that we have both the talent and the experience to continue enhancing the legacy of the All Blacks."
"It's often said that when the tall trees that cast the largest shadows are cut down, the remaining smaller trees grow more rapidly. We believe we'll see players stand tall and take their game to a higher standard this season.
"This group of players, I can assure you, is very excited about the opportunities that lay ahead for them. They know it's their time, their moment, and they can't wait to make their mark in the jersey," Hansen added.
"We're well aware that what we did yesterday will not be enough for today, so we'll be looking to raise the bar to an even higher level from where we've been. This is our challenge - one, I must say, we're really looking forward to getting stuck into."
