Read didn't train with the team on Thursday (Wales time) and has been replaced by Luke Whitelock who will start at No. 8.
With Read out, lock Sam Whitelock will lead New Zealand against the Welsh at Millennium Stadium on Sunday morning (NZ time).
"Whilst it's disappointing to not have 'Reado' [Kieran Read] available, it's a great opportunity to further grow the leadership of the team and, in this case, Sam Whitelock gets the opportunity to captain the side," said All Blacks coach Steve Hansen.
