Hansen said: "The form of the players in Investec Super Rugby has been outstanding and, whilst there is not a lot of change from the Steinlager Series squad, it was still a challenging team to select. It was more a case of who do we leave out, rather than who do we pick.
"We're confident that we've picked the right players for the Championship, with some proven combinations and some Test experience being balanced out by the need to continue to grow the newer players in our environment."
Hansen said the number one goal for the All Blacks, clearly, was to win the Investec Rugby Championship but there were also secondary goals supporting that.
"One is to re-establish our team, from a leadership and playing point of view. The second goal is to grow the understanding and confidence of our newer players, both on and off the track; and thirdly, we want to play a standard of rugby that we can all be proud of and excited by," he said.
"The quality of the opposition we'll face during the Investec Rugby Championship will require a growth in our physicality, intensity and the standard of our preparation. How well we do that will be reflected in our results. It's going to be a very competitive Championship, which we're all really looking forward to.
"By the end of the tournament, we'd expect to have a greater understanding of where the 32 individual players are at, and their ability to cope and perform at Test level."
The All Blacks squad will assemble on Thursday this week for a two-day camp on Auckland's North Shore minus the five Hurricanes who are preparing for this weekend's Super Rugby final against the Lions. Five additional players will also attend the camp: McKenzie, Tamanivalu and their fellow Chiefs back Anton Lienert-Brown as well as Blues loose forward Steven Luatua, Blues outside back Melani Nanai and Crusaders loose forward Matt Todd.
Following this week's camp, the All Blacks will re-assemble in Auckland next Thursday, August 11.
The squad will play training matches against Counties Manukau and Northland in the "Game of Three Halves" event at ECOLight Stadium in Pukekohe on Friday, August 12 before heading to Sydney on Sunday ,August 14.
