Il Nuovo Postiglione - Rugby chiefs unveil 'watershed' Nations Championship

Organisers said the new biennial tournament signalled a "watershed moment for rugby union, years in the making" and would transform the two existing international playing windows, in July and November.

The Six Nations teams will represent the northern hemisphere, and face the SANZAAR nations (South Africa, New Zealand, Australia and Argentina), plus invitational teams Japan and Fiji, representing the southern hemisphere.

Each side will play six fixtures, taking on each of their hemisphere rivals from the opposing group before a Nations Championship Finals Weekend, to decide the tournament champion and winning hemisphere.

London will host the inaugural Finals Weekend, with three days of double-headers at Twickenham in November 2026.

Organisers said the championship would inject "jeopardy and context into every fixture".

Tom Harrison, CEO of Six Nations Rugby, said: "The Nations Championship has the power to redefine the future of rugby, and the partnership between Six Nations Rugby and SANZAAR signals a tectonic shift in the sport.

"Rugby's strongest nations have collaborated with a clear vision to grow the game, by challenging traditional ways of operating to create a tournament structure with genuine global relevance, which will unlock the true value of the sport."

Brendan Morris, CEO of SANZAAR, said the establishment of the Nations Championship was a "historic and exciiting move".

The first round of Nations Championship matches, on July 4, includes a series of blockbuster matches, with South Africa hosting England, France travelling to New Zealand and Australia facing Ireland.
