Brook was fined and given a final warning over his conduct following the incident. But that only came to light more than two months later, after the final Test against Australia in Sydney.
In January, 27-year-old Brook said supporters have “every right to be annoyed” with his behaviour as he issued a public apology.
But he also stated he was on his own when the bouncer “clocked ” him and only later admitted other players had been present. He explained he had lied about that because he had been trying to protect his team-mates from further scrutiny.
It also emerged the Cricket Regulator was looking into the matter.
England’s players were widely criticised for their off-field behaviour during the Ashes, including claims of excessive drinking during a mid-series break in the coastal resort of Noosa.
Tongue, 28, told BBC Sport earlier this week he had learned from what had happened in the New Zealand capital and is “just trying to focus on the cricket now”.
During a meeting at Lord’s to discuss the findings of a review of the tour last week, England’s managing director Rob Key said there is not an “easy fix” to cricket’s relationship with alcohol.
