The trio will look to win New Zealand's first medals in sailing at a Youth Olympics.
It will cap off a busy few months for Tauranga-based athletes van der Zalm, and ten Have who are currently in France competing in the RS:X youth world championships and will travel to the United States to compete in the upcoming youth sailing world championships.
Ten Have will then return to Europe for the sailing world championships in Denmark where New Zealand's top sailors have their first chance to qualify boats for the 2020 Tokyo Olympics.
The Olympics is on the agenda for both van der Zalm and ten Have, but the Youth Olympics is their first ambition.
"The level in the sport is so high, but I believe a realistic goal is top five [in Buenos Aires]," van der Zalm said. "I want to be in the top and fighting for a medal.
"I am looking forward to the entire experience, from meeting new friends to being involved in one of the biggest competitions in the world."
Van der Zalm had made good strides over the past 18 months and was inside the top 10 at last year's youth sailing world championships in China in his first major international regatta.
The Youth Olympic Games run from October 6–18, 2018, in Buenos Aires, Argentina.
