The Dave Rennie era is upon the All Blacks, and the new head coach is determined to make some tactical shifts for the All Blacks ahead of their upcoming matches.

The pressure's on for Rennie to make a difference, with 122 days to go until his first test against France in Christchurch.

Former All Black and Sky Sport commentator, Jeff Wilson, says Rennie's contract lasts until the end of the men's Rugby World Cup in November 2027, which isn't long.

"This is, as Dave Rennie himself said, a bit of a sprint. He obviously fitted the brief that they were looking for and I think he'll go in there and he'll be aggressive and try and make quick changes."
