Archer, 24, said he was subjected to racism from the stands after he was out on the final day of England's innings defeat in Mount Maunganui.

"Everyone has made sure he's OK and let him know we have his back and we're supporting him," Root said.

"He has dealt with it very well; he'll be absolutely fine to play."

The boards of both countries are investigating the abuse against Archer, which he says came "from one guy" at the Bay Oval.

Barbados-born fast bowler Archer made his England debut in May and has captured 23 Test wickets in five matches and 23 wickets in 14 one-day internationals, featuring in the World Cup final victory over New Zealand in July and the Ashes.

"He's dealt with so much already for such a young man," Root added.

"It's impressive to see his attitude and how he continues to stay generally pretty level."

England vice-captain Ben Stokes, who was born and raised in New Zealand until leaving with his family to move to England aged 12, said: "It's a shame because that doesn't represent what New Zealand is about as a country whatsoever.

"I think what New Zealand represents is how much support Jofra's had, not just from the New Zealand cricket team but New Zealand in general after that incident."

New Zealand captain Kane Williamson said he planned to apologise in person to Archer for the "horrific" racist abuse.

"It's against everything that we as Kiwis are about," Williamson said.

New Zealand have confirmed that all-rounder Daryl Mitchell will make his Test debut in Hamilton in place of the injured Colin de Grandhomme.
