The Santiago Phelan-coached side trained at the Hutt Recreation Ground in Lower Hutt this afternoon as former All Blacks coach Graham Henry joined the team to continue his duties as part of their coaching staff.
No 8 Juan Martin Hernandez Lobbe will captain Argentina in what will be his 46th test.
The Pumas will name their reserves on Thursday, while the All Blacks will announce their playing 22 on the same day.
