The 19-year-old Ioane, who All Blacks coach Steve Hansen has earmarked as a potential centre, has just returned from the Rio Olympics, where he was part of New Zealand's rugby sevens team.
Utility back Damian McKenzie and centre Seta Tamanivalu, both of whom were in the squad for the June series against Wales but not included for the Rugby Championship, have also been called into the team on Monday.
McKenzie did not play in June, while Tamanivalu made two appearances off the bench.
Hookers Liam Coltman, uncapped, and James Parsons, who was called in as a replacement on the end of season tour in 2014, have also been summoned to Wellington after Nathan Harris (knee) and Codie Taylor (concussion) were injured in Sydney.
The loss of both hookers last week meant Hansen was forced to field first choice Dane Coles, despite the Wellington Hurricanes hooker suffering pain from a rib cartilage injury.
