Richie McCaw and George Whitelock were defensively outstanding on Friday night and the All Blacks' skipper prefers the openside flanker position rather than No8, although he played at the back of the scrum in the third test against Ireland a few weeks ago and has filled in there for the Crusaders.
Blackadder could leave McCaw and Whitelock where they are and bring in Luke Whitelock or Matt Todd at No8, with the latter possibly getting the nod due to his greater experience.
No matter the personnel, Blackadder hopes his side maintain their intensity levels after reaching new heights against the Chiefs.
"I know we're a far better side than we showed on Friday and we will get better," he said. "We have to keep focusing on getting the little things right. I definitely feel we've had a shift in mindset."
Carter, who strained a hamstring in training for the third test against Ireland and, like Read, also missed the Hurricanes loss, controlled the game expertly when facing up against All Blacks' teammate Aaron Cruden. Even better news for Blackadder afterwards was that he felt no ill effects from the match.
"That was just about the best news I'd heard all week," Blackadder said.
