"I'm nice to everyone, well I try to be, but your special [sic], we get along great and I love talking to you."
Luff was 25 at the time and the volleyball and basketball coach for the Southern Regional Team. The girl was in the teams but studied at another school.
After a school sports competition the student sent Luff a Facebook friend request and they began messaging on Facebook, Snapchat and via text. Students knew they were texting and Luff was seen with the student in his car.
Luff was warned by the principal at his school to maintain a professional boundary but instead conspired to be "more subtle and discreet" in his contact with the girl.
He continued to prolifically message her on social media, with content of an intimate nature and late at night, and kept meeting her.
When the girl's mum intervened Luff tried to get the student to lie that they had not met up. He also told her when she had finished her schooling "no one will care".
The New Zealand Teachers' Disciplinary Tribunal found Luff's behaviour amounted to serious misconduct and "bears the hallmarks of sexual grooming". His attempt to have the student collude with his dishonesty was an aggravating feature and proved he knew the relationship was wrong.
It was likely to have adversely affected the learning or well-being of the student, the tribunal found. It had a negative impact on Luff's fitness to teach and brought the teaching profession into disrepute.
The tribunal said Luff had a responsibility to maintain professional boundaries.
"Students should be free from any type of exploitation, harassment or emotional entanglement with teachers."
His registration was cancelled.
Luff, now 27, declined to comment when he was contacted by the Herald.
He has since moved to Alexandra where he works as a heat pump installer and was made the youngest president of the Alexandra Musical Society in June this year, Fairfax reported.
