The boy's younger brother was also involved and has come forward as well, Mr Henderson said.
Some of the stolen goods were recovered but other items had been passed on and were still being tracked down.
He would be working with the family to arrange compensation if necessary, he said.
"I don't want them to be disadvantaged ... [but] we want our money as quickly as possible."
The Trev's Sports Facebook page received about 16,000 hits and the Wairarapa Times-Age Facebook page received 6000 hits on the story.
The other two boys have also been identified and their details passed on to the police, Mr Henderson said.
He will be looking into the possibility of putting barbed wire on the internal wall that was used to access the shop.
Police confirmed several people had come forward in relation to the incident.
