Richie Mo'unga will end a three-year international exile when he starts at fly-half for New Zealand against the Springboks in the fourth and final Test of the Rugby's Greatest Rivalry series in Baltimore on Saturday.

The 30-year-old last wore the All Blacks jersey in the 2023 Rugby World Cup final at the Stade de France, a match the Springboks won to claim back-to-back titles. His return displaces Ruben Love, who had started all six Tests under head coach Dave Rennie this year, and signals a significant shift in selection philosophy as New Zealand attempt to square the series.

Codie Taylor will captain the side from hooker, leading an entirely new front row alongside props Fletcher Newell and Ethan de Groot. Taylor steps into the leadership role with regular skipper Ardie Savea ruled out through injury. The reshuffle extends across the pack, where Ethan Blackadder earns his first Test start under Rennie at openside flanker and Peter Lakai fills the number eight vacancy left by Savea.

Backline Overhaul

Beyond Mo'unga's recall, the backline features further alterations. Josh Moorby replaces Leroy Carter on the wing, while Anton Lienert-Brown comes into the midfield for the injured Quinn Tupaea. Jordie Barrett retains the inside-centre berth, with Damian McKenzie and Will Jordan completing the back three. Cam Roigard partners Mo'unga at halfback in what represents one of the most heavily revised All Blacks line-ups of the Rennie tenure.

The bench carries an all-Hurricanes front row of Asafo Aumua, Xavier Numia and Tyrel Lomax, with Rennie maintaining a five-three split. Josh Lord returns as lock cover after missing the second and third Tests through concussion, sustained in a head clash with De Groot. Wallace Sititi provides the remaining forward option, while Kyle Preston continues at scrum-half.

Stakes for Baltimore

The scale of change underscores the stakes for New Zealand, who trail two-one in the series and face a Springbok side that has dominated recent encounters between the nations. Mo'unga's reintroduction offers tactical flexibility and goal-kicking security, qualities Rennie will hope can unlock a South African defence that has conceded sparingly across the opening three fixtures. Whether the recalibration proves sufficient to level the ledger will hinge on set-piece stability and the cohesion of a forward pack featuring multiple personnel shifts. For the Springboks, the challenge is familiar: nullify New Zealand's attacking threats and impose the physical template that has served them so effectively in this rivalry.
