Weber will replace scrumhalf Folau Fakatava, who has suffered a season-ending knee injury, while lock Tuipulotu covers for Sam Whitelock and McKenzie for outside back Will Jordan, who both have inner ear issues.
Brothers Beauden, Jordie and Scott Barrett stayed behind in New Zealand after the death of their grandmother but should arrive in Tokyo later this week in time for Saturday's match, New Zealand Rugby said in a statement. Hooker Aumua will travel to Japan on Sunday as cover for Dane Coles, who is "managing" yet another calf issue.
All of the replacement players have been brought in from the All Blacks XV squad, which is preparing for matches against Ireland 'A' in Dublin on November 4 and the Barbarians at Tottenham Stadium on November 12.
"Players are able to re-join the All Blacks XV on tour," the statement added. "Any potential extra additions to the All Blacks XV are being worked through now."
The All Blacks travel on to Wales, Scotland and England to play November tests in successive weeks after Saturday's match against the Brave Blossoms at Tokyo's National Stadium.
