Cruden was hoping to be back to full fitness in time for the first pre-season game, after badly injuring his knee last year, but Rennie said they would keep him off the paddock for another week.
"We won't use Aza at all. We have been increasing his contact stuff and he is going pretty well, but we want to keep building that up. He will play a big part in the Blues trial game."
Rennie said they always enjoyed playing in Rotorua which had a great stadium and the community came out in force last time they were here.
"It is a good surface ... and I think the great thing last year was the community showed they were really interested and turned out in good numbers, which was certainly higher than expectations, so we are excited to go down there again.
"We did want to play [this game] in Tauranga to be honest.
"With not playing at Baypark we were pretty keen to reward that community as well, they are big supporters but we couldn't make it happen unfortunately.
"So, you know, with a bit of luck maybe the stadium will get a bit of a push there and we would certainly love to play there again."
The Chiefs boast a strong contingent from the Bay of Plenty Steamers in their squad this year. Players like Chase Tiatia, Ziggy Fisiihoi, Johan Bardoul, Nathan Harris, Brodie Retallick, Sam Cane, and Mike Kainga should all be available tomorrow.
Unfortunately for the Chiefs, they have lost halfback Augustine Pulu for much of the season after he broke his arm playing for the All Blacks Sevens last weekend in Sydney.
"There is a lot of competition for places and we have certainly been pushing that", Rennie said.
