Kate Feltham, lawyer for the PCC, said the man's offending was prolonged and repetitive, and sexual activity with the student occurred up to three times a week. It also involved a degree of sexual grooming and an abuse of authority, she said.
The practitioner was "a father figure in the household" and took advantage of the student's vulnerability. Her command of English was poor, Ms Feltham said.
While the practitioner admitted his behaviour reflected adversely on his fitness to practice, and that it brought his profession into disrepute, he believed - with certain conditions - he should be able to return to his work.
"When my job became difficult I put more and more of my life into my career and less into what should have been my most important relationship, my marriage and my family," he said in evidence today.
"Our 17-year-old student was reliant on our family to help her adjust to New Zealand for her pastoral care. She appeared to take a liking to me and I repaid her trust and affection by starting an inappropriate relationship with her.
"I am deeply remorseful for this and the lasting effect that this will have for her."
"I am deeply sorry. I will never place myself in a position where my job becomes more important than my family."
His wife, who was supported at the hearing by her friend, sister and mother, also gave evidence in support of him at today's hearing.
The practitioner's lawyer, Matthew McClelland, said a 10-and-a-half month suspension - taking into account the time he had been unable to work due to his home detention sentence - was the appropriate penalty.
He told the tribunal his client had already been punished by the High Court, and referred to his spotless complaints record with patients.
Before returning to work, he would undergo a psychological assessment approved by the appropriate professional council, and would also stick to strict supervision and reporting conditions once he was back on the job, Mr McClelland said.
The practitioner also planned to continue working with his psychologist and family doctor to address his issues, Mr McClelland said.
The tribunal reserved its decision in the case.
Last July, the practitioner was handed a sentence in the High Court of nine months' home detention and ordered to pay $10,000 in reparation.

* On the impact of the convictions: "The financial stress has been awful. We've had to go on the unemployment benefit, which has been humiliating and demeaning and inadequate."
