Sonny Bill Williams and George Moala are the notable inclusions to the All Blacks squad to play in the Rugby Championship which starts in three weeks with a test against Australia in Sydney.
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."
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.
