Tauranga Rowing Club president Simon Aubrey says Ling's success comes as no surprise to anyone who has known him over the years.
"He is a good lad, who has been in the system a long time and has worked incredibly hard. He is very dedicated," Aubrey said.
Aubrey thinks the Christchurch earthquakes may have been the making of Ling, who was at university there, as he was forced to work on his stamina indoors.
"He couldn't row in Christchurch for 18 months. Every day he did an hour on the ergometer. I think that was the basis of his new-found belief."
Two Tauranga Rowing Club members, Zoe Stevenson and Curtis Rapley, qualified for Rio at the world championships.
Stevenson and Eve Macfarlane took out the women's double ahead of teams from Lithuania and Great Britain, while Rapley was part of the men's lightweight four with James Lassche, Alistair Bond and James Hunter.
Aubrey says the club's high profile stars inspire the next generation of rowers.
"Those athletes come and see the club members and go out with them on the water a couple of times a season. They come and speak to them and keep in touch on social media. It is very inspiring."
Meanwhile, former Tauranga resident Mahe Drysdale is in line to win a record sixth world single sculls title.
