The new biennial Nations Championship opens on 4 July with a blistering Super Saturday, featuring six Test matches across three continents. New Zealand takes on France in Christchurch’s One New Zealand Stadium, while Australia faces Ireland in Brisbane and South Africa squares off with England in Johannesburg.

A 9‑hour slate delivers nonstop action, with kick‑offs staggered from 08:10 BST to 20:10 BST. Fiji plays Wales in Cardiff and Argentina meets Scotland in Córdoba, ensuring fans worldwide catch high‑stakes clashes without travel gaps.

The format stitches together every Six Nations side against the Southern Hemisphere’s top teams, creating a narrative that runs through July and November. Standings in each hemisphere pool determine the final weekend match‑ups at Twickenham’s Allianz Stadium, where a grand final will crown the inaugural champions.

ITV Sport holds UK broadcast rights, promising widespread coverage. The tournament’s structure offers a fresh rhythm to the Test calendar, giving teams a clear pathway to a continental title and a new competitive edge.
