The difficulties have been accentuated for van der Kaay as the national body has seen their funding decreased in recent years.
"Financially it has been pretty hard with Tri NZ having funding cuts," said van der Kaay. "This is going to make a huge difference releasing the financial pressure."
As well as financial support, the programme offer a variety of initiatives to help athletes be their best, both inside and outside their chosen arena.
"There are other aspects, like developing your own brand and learning about finance," said van der Kaay. "I'm looking forward to the programs. I love the self development stuff, investments and finance, athlete specific stuff. I'm pretty excited to be a part of that and developing myself."
Achieving the right balance has been vital for the 23-year-old, who knows that the pressures can be overwhelming.
"It's about balancing it all; your work, life and social," said van der Kaay. "If you dive all into training, or all into work to try and fund training it's not good. [It's about] keeping a healthy mindset and motivated for training."
Van der Kaay's international breakthrough came at the 2018 Commonwealth Games. She claimed a bronze medal in the mixed relay with teammates Andrea Hewitt, Tayler Reid, and Ryan Sissons and was the best-placed Kiwi in the women's triathlon, finishing seventh.
As part of the young mixed relay team, van der Kaay continued that momentum this year, and they are currently ranked fifth in the world, with one more race in the series next year (the top eight gain passage to Tokyo).
"Qualifying for the Olympics would be a dream," said van der Kaay. "It's been a goal for a long time now. We are performing well in the mixed team relay — we have been on the podium a few times so we have a good chance."
