Coach Michael Cheika has kept faith with the rest of the starting XV and bench that defeated Wales 29-17 in their quarter-final clash in Marseille, including another start for Santiago Carreras at fly-half.
The side will be captained by hooker Julian Montoya, having won their last four games in a row since an opening defeat to England, a feat they have not achieved since the 2015 World Cup.
He makes up a front row that also includes props Thomas Gallo, who has beaten more defenders than any other forward in this year’s tournament, and Francisco Gomez Kodela.
Guido Petti and Tomas Lavanini are the lock pairing, while the powerful back row contains number eight Facundo Isa, earning a 50th cap, and flankers Juan Martin Gonzalez and Marcos Kremer.
Juan Cruz Mallia is at full-back, Mateo Carreras and Emiliano Boffelli on the wings, and the centre-pairing contains Santiago Chocobares and Lucio Cinti.
Veteran hooker Agustin Creevy, who has been involved in many a battle with the All Blacks down the years, is on the bench along with experienced fly-half Nicolas Sanchez, who has scored the second-most points of any test player against New Zealand (151). Only Australia’s Matt Burke has scored more (176).
Creevy will be aged 38 years and 219 days on Friday and become the oldest player to feature in a World Cup semi-final, surpassing South Africa’s Victor Matfield who was 38 years and 166 days against the All Blacks in 2015.
Argentina are seeking a first World Cup final appearance from their third semi-final but have won only two of their previous 36 tests against New Zealand, though those wins have come since 2020.
There are six players who featured in both those previous victories - replacement lock Matias Alemanno, Bertranou, Santiago Carreras, Kremer, Petti and Montoya.
