He knows there is plenty of improving to be done. With Highlander Colin Slade - Carter's previous understudy before a run of injuries - and Hurricane Beauden Barrett, waiting, there will be no room for slippage.
The first sustained contact Cruden and his fellow All Blacks will have with the national coaches will be at the first of two training camps in Mt Maunganui on May 19.
"I'm reasonably happy with it I suppose," Cruden said of his form. "I think I can contribute more around the paddock and I suppose as a first-five you always want things to go smoothly, so when things get a bit loose you take it on your own shoulders to try to rectify that."
Cruden, who started in all of the Chiefs' 18 matches last season and is perhaps even more central to the team's hopes this year in the absence of Sonny Bill Williams, is one of the competition's form first-fives.
His kicking variations in the close defeat by the Stormers in Cape Town reaped two tries, but a duffed grubber in front of his posts gave the opposition seven points.
He does not believe the ever-changing nature of the Chiefs' midfield is an issue. Andrew Horrell will tonight become the third second-five for the Chiefs this season when he takes the field against the Highlanders at Waikato Stadium - after Bundee Aki and Charlie Ngatai.
"It's a matter of finding that consistency. Rugby is a pretty simple game when you can get that go-forward ball and that's what we're striving for."
