The board requested that the information from police about the timing and detail of the offence be provided to Tuetue.
At last month's hearing, Tuetue changed his stance and acknowledged he was responsible for the crime.
He said he had not been prepared to discuss it before, but following the death of one of his supporters, and on reflection, he wanted to take full responsibility for all his offending.
Tuetue did not seek parole.
The board said he has been removed from reintegrative activities because of the risk of prosecution and a further finite sentence, which would affect his eligibility for parole.
The board noted another of his victims opposed parole because he had not yet fully disclosed his offending to family and friends.
