At a preliminary stage of the committee's investigation, the teacher said it was not his intention to continue teaching.
The concluding paragraphs of his letter to the committee stated: "Finally I would like to say that teaching is not a particularly well paid occupation which I took up because I thought I could do some good."
The hassle of the investigation was not worth the compensations, he said.
"I have been so mentally and physically stressed by these events that I will not be teaching in a school either primary or secondary in the foreseeable future, even if the NZTC allows me to keep my registration.
"Hence, I no longer really care what happens from here on. So if you want to deregister me please do so quickly so I can get on with the rest of my life."
The teacher denied that there was anything improper - sexual or otherwise - in his relationship with the student, however accepted he had failed to maintain appropriate boundaries and as a result was not "safe".
He said the student slept in his bed without any coercion or persuasion "based I would speculate on his need for a surrogate father figure".
The tribunal found the teacher guilty of serious misconduct, censured him and cancelled his registration.
