John Kirwan's read on the All Blacks' Nations Championship squad is that the experimentation phase is nearly over — Rennie has used 50-plus players through 2026, but the November window is likely the last chance to trial fringe options before the Rugby World Cup squad crystallises. Kirwan identifies the lock selection as the only genuine surprise, with Jamie Hannah jumping Sam Darry and Patrick Tuipulotu despite both featuring in the series against the Boks. The subtext there is whether Rennie is hunting for a specialist six rather than a pure lock. In the back three, Kirwan sees Chay Fihaki's selection over Emoni Narawa as a bet on X-factor, while Leicester Fainga'anuku's dual role as outside back and loose forward remains the biggest talking point. For Springbok fans, the relevant context is that New Zealand's only losses in 2026 were their 3-1 series defeat to South Africa — and this entire squad-building exercise is framed around eventually solving that problem.
