Read has not played since breaking a thumb in April, having spent much of 2017 recuperating from wrist surgery.
The skipper is unlikely to play any part in the All Blacks' practice match against Samoa on Friday as plans for the first Test in a fortnight at Eden Park draw into sharp focus.
But having seen Read's predecessor Richie McCaw have huge impacts on previous series with similarly low-key preparation, Hansen has no concerns.
"Our last skipper used to be able to do it, and this one's got similar mental fortitude and strength of character," Hansen said.
