Togia Tuliau pleaded guilty last year to eight charges of sexual connection and one charge of indecent assault.
The victim, a member of Tuliau's church, was abused by him several times last year while she was staying at the pastor's house.
The presiding judge, Mata Keli Tuatagaloa, said Tuliau neglected his duty of care to her and abused his respected position as a church pastor.
