Christopher Reive runs you through all you need to know ahead of the All Blacks test against Argentina in Nelson.
All Blacks v Argentina, 7.35pm kick-off
In 2012, Taylor Swift serenaded the world with the words "All I know is a simple name, everything has changed." You could imagine a similar message being spread in the South Island and among the Richie Mo'unga bandwagon with the Crusaders No.10 given his first All Blacks start. Mo'unga's call up was one of a handful of changes to the match day 23 made by Steve Hansen, with Shannon Frizell, TJ Perenara, Karl Tu'inukuafe, Nehe Milner-Skudder, Ardie Savea and Scott Barrett joining the starting 15. Argentina aren't without changes, though not to the extent of the All Blacks. The experienced Martin Landajo returns in the No.9 jersey, while Jeronimo de la Fuente, Santiago Garcia Botta and Tomas Lezana also join the run-on side.
All Blacks:
15. Ben Smith, 14. Nehe Milner-Skudder, 13. Jack Goodhue, 12. Ngani Laumape, 11. Waisake Naholo, 10. Richie Mo'unga, 9. TJ Perenara, 8. Kieran Read, 7. Ardie Savea, 6. Shannon Frizell, 5. Scott Barrett, 4. Brodie Retallick, 3. Owen Franks, 2. Codie Taylor, 1. Karl Tu'inukuafe.
