Coach Scott Robertson has made four changes to the run on side.
De Groot replaces Tamaiti Williams, who drops to the bench, while Caleb Clarke takes over from Mark Tele'a, who misses out on the matchday 23.
Will Jordan moves to the right wing, pushing Sevu Reece to the reserves, with Barrett at fullback.
The loose forward trio of Ardie Savea, Sam Cane and Wallace Sititi remains unchanged, while captain Scott Barrett and Tupou Vai'i are at lock.
Cortez Ratima again starts at halfback inside Damian McKenzie, with Jordie Barrett and Rieko Ioane in the midfield.
With prop Fletcher Newell unavailable due to injury, Pasilio Tosi comes on to the bench alongside Asafo Aumua, Williams, Sam Darry, Luke Jacobson, TJ Perenara, Anton Lienert-Brown and Reece.
The All Blacks have held the Bledisloe Cup since 2003 and are favourites to retain the trophy again this year.
