England said Jofra Archer had moved on from the racist abuse and was ready to fire in the second Test at Hamilton.
England, though, have another injury concern over wicket-keeper batsman Jos Buttler, who pulled a back muscle while exercising.
"He has dealt with it very well," Root told the BBC. Archer, in his column for Dailymail, wrote that he has "moved on" and was eager to contribute for his side in the second Test.
England captain told journalists that he was not in a position to announce the playing XI over a potential injury concern for Jos Buttler.
"We'll have to find out more information about that today and tomorrow to see where he's at," Root said.
Ollie Pope is being considered to take over the wicket-keeping duties if Buttler doesn’t take part but according to Root, there were a few other possibilities which would depend on the pitch at Hamilton.
New Zealand have also a decision to make whether to include Matt Henry or Lockie Ferguson in place of injured Trent Boult.
Ferguson, just like Jofra Archer, can bowl up to 150 clicks while Henry is more of a pitch-it-up bowler who can move the ball both ways.
New Zealand have confirmed the inclusion of Daryl Mitchell in the playing XI as he will replace Colin de Grandhomme, who has to sit out with a torn abdominal muscle.
