He is still icing the knee heavily.
"With the injury I haven't been able to put as much work into my kicking as I would have liked.
"I missed a few on the weekend, that's going to happen, but it's slowly coming back and it's a matter of me trusting my technique and going through the systems."
Cruden this week re-signed with the franchise through to 2014 after switching from the Hurricanes in the off-season.
Instructions to his agent were clear - he's settled in Hamilton and is enjoying his footie so get a deal done.
"I told him if there's an offer be sure to take it and put pen to paper quickly. Negotiations are on the backburner now and I can focus fully on the footie."
Chiefs coach Dave Rennie brought Cruden with him from Manawatu to Hamilton and rates his pivot at the very top of the pack chasing Dan Carter, albeit with a few kinks in his game still to be ironed out.
"He's got some strides to make yet. Aaron's a bloody good player, fantastic with ball in hand, brave and good at making space for others. His goalkicking is coming on but the area he wants to focus on is controlling a game with his boot.
"We know he can do it ball in hand really well but that's an area of his game he is trying to grow."
With first-fives Gareth Anscombe and Tyler Bleyendaal starting to blossom on the bigger stage, Rennie still backs his boy as the one to keep the heat on Carter.
"There's a couple of young guys coming through and they're all guys who have come out of the (national) 20s programme so I know them all really well. But I still rate the guy we've got here at the top."
Cruden, who will get his first taste of playing at Baypark Stadium tonight against the Brumbies, said Rennie's worth as a coach was starting to fully emerge after the Chiefs' two win/one loss start to the season.
"It's great to see how Dave's evolving and coming up with a few new tricks, and with Wayne Smith, Andrew Strawbridge and Tom Coventry involved too they're working well off each other.
"It's good to have that many coaches so it's not the same guy barking the same things at you all the time."
