But the country has a growing list of strong surfers who could also be contenders to compete at Japan in 2020.
Kiwi surfer Ella Williams said the qualification process was a big announcement for Kiwis and others outside the Tour.
"We have so much potential and talent in New Zealand, but time will tell who puts in the work. It's one of those sports where you have to keep on working at it," the 22-year-old said.
"I like that idea. It mixes things up. It gives some of us surfers who are still trying to get on to the World Tour an opportunity to be part of it. I think that's exciting."
The former junior world champion has been a strong competitor on the ISA World Games stage, finishing in the semifinals the past two years.
And while Olympic qualification is among her goals, the proposed qualification process will not change her focus.
"It's definitely a goal and a dream of mine to compete at the Olympics in surfing, but at the moment, I'm just taking things comp by comp, heat by heat, and trying to qualify for the World Tour."
With fewer Olympic spots guaranteed to the WSL than many expected, Williams said more Tour surfers will contest the ISA World Games as a result.
This year, just three of the 18 full-time competitors on the women's Tour took part in the World Games, and only two of the 35 men.
"You'll see it, for sure. There'll be more of those World Tour surfers at the World Games now, because who doesn't want a spot at the Olympics?"
WSL chief executive Sophie Goldschmidt said the Olympics offered an incredible platform for the sport and she expected it would benefit from its debut in 2020.
"It is essential for surfing to showcase its best possible surfing through this opportunity and that requires the world's best surfers from the Championship Tour to participate," she said.
"It's great that the ISA and WSL, in conversation with the athletes, could come to an agreement on the qualification process for 2020. We look forward to enhancing the partnership as we get closer to this fantastic opportunity."
The qualifying process must be approved by the International Olympic Committee's executive board in February.
