Injury to Dan Carter and a rotation policy at hooker mean that Aaron Cruden and Andrew Hore will start this weekend in Argentina.
In the absence of Richie McCaw, no. 8 Keiren Reid will again captain the men from New Zealand, whilst the workload of young hooker Dane Coles is being managed, as he drops out of the match day squad for Hore, who will play his 80th test match in the famous black jersey.
Head Coach Steve Hansen said, “This game has huge significance with regard to us having any chance of winning the Rugby Championship.
“Playing Argentina at home is never an easy assignment so we have worked hard on, firstly, our recovery on arrival and, secondly, our preparation throughout the week. We know that we will have to be physically on top of our game and strategically smart.
“As always, we are expecting a huge challenge from the Argentina and a very vocal crowd but everyone is looking forward to embracing this challenge.
“The city of La Plata has had its difficulties since we were here last, with the flooding, so it is an opportunity for both teams to bring something positive to the region.”
Commenting on the change at hooker, he said: “We are very happy with where Dane is at and with his performances of late. But like a lot of the young players, we are also mindful of managing their game time as part of their development so have brought in Andrew to start this week.”
