Captain Berry captured two Māori chiefs responsible for the massacre, at first holding them for ransom for the return of survivors. After the survivors were returned, Berry told the chiefs that they would be taken to Europe to answer for their crimes unless they released the "Boyd's" papers. After the papers were given to him, he released the chiefs. He made it a condition of their release that they would be "degraded from their rank, and received among the number of his slaves", although he never expected this condition to be complied with.
