"The incident in question was not school-related [and] it was not a certainty that Mr Simpkins was going to be convicted. He may well have been discharged without conviction," it said.
"The board will meet as soon as all details and advice are at hand. The principal and board chairman are in the process of gathering that advice at this time.
"Mr Simpkins is as of today [Tuesday] on leave until the school and the board have been able to gain the necessary advice and consider the implications of yesterday's decision by the court."
Parents of the school will be notified when the board comes to a decision.
Education Minister Hekia Parata did not comment, directing the questions asked by the Rotorua Daily Post to the Ministry of Education.
Ministry of Education head of sector enablement and support Kim Shannon said the ministry was concerned about the incident and had been in touch with the school.
"As the legal employer of all staff in a school, boards of trustees are required to apply the law as it relates to employees, particularly when a court has convicted a member of staff.
"Now that the court proceedings are over and the outcome known, the board of trustees is again seeking advice from the New Zealand School Trustees Association and considering their options in relation to this advice.
"The school will have policies and procedures in place for vetting of all staff. These policies will be in line with the requirements of the Vulnerable Children's Act."
Labour Party education spokesman Chris Hipkins said schools had a responsibility to ensure all those working with children were appropriately vetted.
"A decision about whether to stand someone down is ultimately one for the school to make, but I would expect them always to act in the best interests of their students and avoid exposing them to unnecessary risk.
"It's difficult to legislate for every possible scenario, and ultimately schools will always need to make careful judgments depending on the details of any situation."
According to the summary of facts, during the incident Ngarimu Simpkins pinned one boy on the ground and punched him in the head more than once.
He also kicked or punched the boy in the stomach, winding him, and later punched one of the boys in the face, knocking him to the ground.
Two boys were taken to hospital where they were treated for injuries.
The grandmother of one yesterday told the court he was an innocent bystander who had been destroyed by the assault.
