With the injury of Scott Barrett, the All Blacks have confirmed Ardie Savea will captain the side in both home Rugby Championship tests against Argentina.
A second change is that Blues first-five Harry Plummer has also been added to the squad after an injury to Stephen Perofeta.

Barrett injured a finger during the All Blacks 47-5 win against Fiji in San Diego, which required a surgical treatment after his return to New Zealand.
All Blacks assistant coach Jason Ryan confirmed the changes on Monday and said Argentina were never easy to beat.
"Argentina bring a different intensity to the first three tests that we had…it should be a good contest, they've been playing really well," said Ryan.
The Pumas, split a series 1-1 with France and thrashed neighbours Uruguay in their three tests so far in 2024.
"I think they've always been a passionate side, they play with energy and momentum. (Matias) Kremer and (Pablo) Matera are big around the breakdown."
Ryan said that the focus now the squad had reassembled for the Rugby Championship was to adapt to challenge that the Pumas, Springboks and Wallabies would pose.
"You've always got to be evolving your game, week to week. We're always trying to tweak things."
The first test at Wellington's Sky Stadium on Saturday (kick-off 7.05pm), with the second match seven days later at Auckland's Eden Park.
