Williamson to miss Australia series under NZC casual agreement

Kane Williamson will miss the upcoming T20I series against Australia but is committed to playing in the T20 World Cup after signing a casual playing agreement with New Zealand Cricket (NZC) alongside Devon Conway, Finn Allen, Lockie Ferguson and Tim Seifert.

The five players were not among the 20 centrally contracted New Zealand players announced in June for the 2025-26 season but have signed casual agreements in order to have some flexibility between playing for New Zealand, remaining within the high-performance system, and taking up franchise opportunities overseas.

Allen, Seifert and Ferguson have existing BBL contracts that will see them play in Australia while the New Zealand Super Smash is taking place. New Zealand women's captain Sophie Devine has signed a similar agreement for 2025-26 as she intends to retire from ODI cricket after the upcoming World Cup in India but remains available for T20Is.

Williamson did not play in New Zealand's most recent Test series against Zimbabwe and also missed the T20I tri-series that preceded it. Instead he played in the T20 Blast for Middlesex, and two County Championship games, as well as the Hundred for London Spirit.

NZC stated that to be eligible for the casual playing agreement, players were required to commit themselves to the T20 World Cup campaign which included home series against Australia, England and the West Indies ahead of the tournament in India and Sri Lanka in February and March. It had previously been confirmed that Allen would miss the Australia matches, to be played from October 1-4 in Mount Maunganui, after undergoing foot surgery.

An exception has been made for Williamson who has made himself unavailable for the series.

NZC CEO Scott Weenink said the casual agreements were sensible arrangements in a T20 World Cup year.

"With such a pinnacle event on the horizon we wanted to ensure our best T20 players were ready and available to push for inclusion," he said. "The casual agreements are a commitment from the players to NZC and the Black Caps, and in return NZC will offer our full support to these players as part of our high-performance system.

"The message from the players is that playing for the Black Caps is hugely important to them and I'm pleased we've been able to agree terms to have them casually contracted for the coming season.

"Rob [Walter] and the team have a massive period of cricket ahead, home and away, and I know myself along with all of our fans can't wait to follow and support."

New Zealand's squad to face Australia will be named later this week.
