Beauden Barrett will travel with the All Blacks to Argentina after being named on Friday to replace Lima Sopoaga in the upcoming Rugby Championship clash against Los Pumas.
Sopoaga is staying home with his partner as they await the birth of their first child.
Barrett was one of six All Blacks originally named to sit out the trip to face Argentina in Buenos Aires on Sunday, after coach Steve Hansen selected a slimmed-down squad of 28.
