HBCA's statement on the outcome of that hearing said Greenwood "suspended the two players from playing until the end of the 2020-21 season, effectively a ban of 10 weeks, including the three-week standdown already served."
Rainger said Heron felt a better approach was to look at how many games they would miss and adjusted it down accordingly.
One player was suspended for 14 games and the other for 10 games after the adjustment.
This means they are free to play again, and both players took the field for the Napier Boys' High School 1st XI (a side coached by Mike Pawson) in their Central Districts competition.
"Mr Heron emphasised that by altering the sanction it does not reduce the seriousness of the conduct," Rainger said.
"He said that the conduct was completely unacceptable and hurtful."
Both hearings concluded that there had been racist and homophobic abuse during a Twenty20 match between a Napier Tech XI and a Western Districts Auckland Blue XI on January 21.
Western Districts Secondary School Cricket Association president Lynn Fuller said she could not comment on the appeal hearing outcome because of HBCA rules that mean only HBCA can comment on the matter.
A spokesperson for New Zealand Cricket said it regards the option to appeal a Code of Conduct finding as "an important part of a just and fair process".
"It is satisfied changes to the sanctions referenced do not reduce, or in any way excuse, the seriousness of the offending described."
