They are both members of the Kaikorai Bowling Club and have played together in interclub games this season.
Fahey started bowls after he retired from the Burnside freezing works 25 years ago, and Jonty has been rolling them up for the past two years.
Fahey was persuaded to start the game by a few friends.
"I have won nothing and my game is just as bad as when I started," he said.
"But I enjoy the companionship and have had a ball.
"I just enjoy coming down to the club. They are a great bunch to be with."
Jonty, a pupil at Balmacewen Intermediate, was talked into starting the game by his uncles - Steve and Peter Wilson - two years ago.
He believes he is the only pupil at his school who is a member of a bowling club.
"Other kids talk to me about bowls," he said.
"But they play cricket and other stuff themselves.
"Bowls is a challenging game and you meet a lot of new people each week."
Bowls is just one of his sporting interests. He also plays futsal, touch and Rippa Rugby and has represented Otago at indoor bowls.
His attitude has impressed Kaikorai president Pat O'Dea.
"Jonty is very relaxed on the green and has got ambitions to succeed in bowls," O'Dea said.
Fahey is a regular in the Kaikorai team for Wednesday interclub competition and fills in where necessary for the Saturday competitions.
He was born in Canada of Irish descent and settled in New Zealand in 1943 when the ship he was working on left without him.
He has a lifestyle farm above Burnside that is now run by his daughter but he still does a few chores. Fahey has the energy of a 60-year-old and has no intention of retiring from bowls.
"I have good genes," he said. "Bowls keeps me healthy and gets me out in the fresh air."
Fahey has been impressed by the play of Jonty and believes he has a good future in the sport.
"Jonty's fantastic," he said. "I would like to be able to play as good as him. When we played together he hit the jack three times in a row."
Jonty wants to represent New Zealand in the future, win a Bowls Dunedin title and win a Kittyhawk (national under-18) title.
The pair received a special presentation at the centennial dinner of the Kaikorai club last weekend for being the youngest and oldest active members of the club.
• Dunedin bowler Peter Wilson suffered his share of misfortune to exit the Welsh grand prix at Swansea yesterday, NZPA reports.
Wilson bowed out in the second round after losing his second-round match 6-6, 8-7 to England's Mark Royal.
Royal needed a lucky last shot to draw the first set as Wilson was 6-4 up and holding on the head, but the Englishman drove, hitting up a short bowl into the head, removing Wilson's shot and tipping the jack back to two of Royal's bowls.
Wilson appeared to lose his weight early in the second set and allowed Royal the early advantage before battling back although a three on the last end was not enough for him to save the match.
