Barrett will extend his record as world rugby's most-capped back when he takes over as skipper from Codie Taylor in his 149th test.
Taylor is replaced at hooker by Asafo Aumua and George Bower comes in at prop in place of Ethan de Groot.
Josh Lord has been chosen ahead of Fabian Holland in the second row, while German-born Anton Segner makes his first All Blacks start on the flank, replacing Tupou Vaa'i.
There is also a first start for wing Fehi Fineanganofo, who comes in for the injured Will Jordan to win his second cap, while veteran Anton Lienert-Brown earns a 95th cap in place of Jordie Barrett at centre.
There is a new halfback pairing as Richie Mo’unga plays at number 10 and Cortez Ratima at scrumhalf. Mo’unga missed last month’s Bledisloe Cup clashes against Australia with a calf tear.
