Scott Robertson (48), widely tipped to succeed Ian Foster (57) as the head coach of the All Blacks after the tournament in France, said on Wednesday he was expecting an announcement to be made soon.

NZR appeared to be caught on the hop by Robertson's comments and later released a statement saying "an announcement about the All Blacks head coach or process is not imminent".

Japan coach Jamie Joseph (53) is another possible candidate to replace Foster when his contract runs out after the World Cup, which will be held in France from September 8th to October 28th.

"What gives us the best chance as an All Blacks team of winning the World Cup is having as little off-field distraction as we can so that all the energy can be going into performance and playing," Cane said on Thursday.

"I just think as long as it's dealt with in a way that's least disruptive for the current group so that there's as little off-field distraction as possible. Whether that's before a World Cup or after, that's not up to me."

Before the World Cup, New Zealand will compete in the 2023 Rugby Championship in July and August.
