Both were granted interim name suppression when they appeared on Friday, and were remanded on bail to appear in court again on June 28.
A bail condition prohibited them from associating with the alleged victims.
A photo showing the boy with blood on his shirt was published online after the incident.
Meanwhile, Cherie Kurarangi is overwhelmed by the support for a playground hui she's co-ordinating to be held at Anderson Park, Napier, on Monday, starting at 1pm.
By mid-afternoon on Friday almost 4000 people had responded to her Facebook post about the hui, and over 570 had said they had been victims-of or witnessed violence in the community.
The site also posed questions for what people wanted done, to make and keep public places safe for children, whanau and community.
Everyone will be welcomed in what she hopes will be a gang patch-free event on what is forecast to be a fine day, and she hopes chapter leaders concerned about what happened on Monday would be among speakers.
