The veteran motorist, who turned 95 on Sunday, has been driving for the past 80 years.
Mr Templeton got his licence in 1930 - just three years after production ceased on the Model T Ford.
"I got my licence the day I turned 15, in Christchurch," he said this week.
"I remember I sat the test in my father's old Redbird Overland. I wish I could claim I've never had a prang, but I've had one or two. I've only had one speeding ticket, though," he chuckled.
"My first car was an Austin Cambridge, which my parents gave me. Since then, I've had a Ford Prefect, a Durant, a New Beauty Ford, which was a bit later than the Model T, a Humber 80, a Hillman Super Minx, a Vauxhall Viva, a Mazda 808 and now a Mitsubishi RVR. It's my second RVR. The first one was red.
"I mainly drive down to the Blueskin store to get the paper and mail, now. But I probably drive into Dunedin four times a week. If I couldn't drive into town I'd become a hermit."
Mr Templeton grew up in Addington, Christchurch, and had ministries in Ashburton, Greymouth, Christchurch and Wanganui, as well as serving as a military chaplain.
He moved to Dunedin in 1956 to become the Northeast Valley Church of Christ minister and lecture at the Bishopgrove Bible College.
"I've been a minister for 69 years. I haven't been disgraced yet. The locals out here have dubbed me 'the Bishop of Blueskin'."
A community function was held at the Waitati Hall recently to celebrate his 95th birthday.
"There were only meant to be 20 people there, but the locals got wind of it and more than 40 turned up," he said, feigning indignation.
In 1996, he was awarded a Queen's Service Order, for his services to the community.
Asked how long he will continue driving, Mr Templeton said: "I wouldn't know".
And then he patiently explained to the ODT photographer how to execute a three-point turn to get out of his driveway.
