Bower (28) comes into the team with Joe Moody under a head injury cloud and fellow prop Nepo Laulala under an injury cloud.
It is a swift rise for Bower, who was not even first choice for his Super Rugby side the Crusaders this season.
Bower was born in Wellington and moved to Dunedin after leaving school. He played one game for Otago in 2014, but then had to wait until 2018 to play another game. He has been in fine form for Otago this year.
Wellington loose forward and captain Du'Plessis Kirifi has also come into the squad.
The squad also features the inclusion of lock Mitchell Dunshea and midfielders Ngani Laumape and Peter Umaga-Jensen who have already assembled with the All Blacks as cover.
