Just don't mention the "R" word around him - retirement, that is.
He has tried it once before, retiring in 1990 after long stints at Kings High School and Kaikorai Valley High School.
He joined St Hildas Collegiate School "to do a bit of relief work" in 1993. That relief work turned into "pretty much full-time" employment.
While there is no compulsory retirement age for New Zealanders, for many workers, 65 or sooner is the target.
But not for Mr Huggett, who celebrates his 75th birthday next Friday.
"As long as I have something to contribute, I will stay. I said to the principal at the time 'I will help out but the moment I don't enjoy it, I will stop'."
Teaching a wide range of subjects, from geography, social studies, art history to his current favourite, Information Communications Technology (ICT), had helped him maintain his enthusiasm for the job - as well as for the pupils.
During his time in front of the classroom he has been quick to embrace new technology to connect with pupils who were increasingly "technically savvy".
"Deep down though, I don't think the kids have changed that much."
Mr Huggett's achievements were celebrated with an early birthday present at a special school service attended by family, friends, staff members and pupils yesterday.
Principal Melissa Bell said Mr Huggett had taught more than 6000 Dunedin pupils during his time and was the most beloved staff member at the school.
"He is everyone's granddad, uncle or dad.
"He is exceptional."
