The assurances that Cane will be available for the Crusaders match in Hamilton suggest he will be fit to play for the All Blacks against France next month. The 21-year-old is the only specialist openside flanker in Steve Hansen's 38-man wider training squad, though Luke Braid or Matt Todd would be only a phone call away.
While the Crusaders are clearly already in Rennie's plans, wisely probably given they tipped over the Chiefs in Hamilton last season, the Hurricanes are at the forefront of his mind.
In the two other changes to the starting line-up, Pauliasi Manu starts at loosehead prop and Charlie Ngatai returns from a hamstring strain to centre, replacing Save Tokula.
"It's a great opportunity for Charlie to make a bit of a statement," Rennie said of Ngatai who is up against his former team, before noting the challenge his side faced against their New Zealand rivals over the coming weeks. "They're brutal these games, with test match intensity, and you've got guys coming up against each other who have aspirations to play higher. It's certainly going to be a tough game and a tough few weeks but it's no different to last year when we played the Bulls and then we had four New Zealand sides to finish off."
He said of the Hurricanes, who looked extremely good in thrashing the Cheetahs in Bloemfontein: "Their backs were against the wall. They've got a lot of character and a lot of very good players. We know full well if we kick poorly and you turn ball over you're going to be punished. They've got a good back three and they've got loosies who are great on the ball.
"A lot of people talk about the fact they have to travel home but I know from our point of view we've won both times we've come back from South Africa in the last two years. I think statistically the side coming home wins more often than not so we're not buying into any of that talk."
Rennie said he was making progress on a midfield replacement for Richard Kahui after their request to sign Casey Laulala from Munster was denied by the NZRU. Rennie said the player he was looking at was in the frame to make the sevens World Cup which could have implications for later in the season, but hoped to make an announcement soon.
Hawkes Bay player Dan Waenga has been named on the bench as cover for first-five following Gareth Anscombe's broken foot.
