"It was a vision we set for the Tokyo Olympics [in 2020] and just shows the depth, acceleration and growth in the sport that we have a chance to achieve it in 2016."
New Zealand would have hoped to get more than nine across the line at the worlds last year, but the men's quad missed out by 0.06s and the women's quad were sixth in the A final, but needed to be in the top five to advance directly to Rio.
Peterson says the success of New Zealand at the under-23 world champs two years ago, when the country topped the medal table for the first time, is often overlooked.
"That's where the men's eight came from and a lot of depth in the women's programme. That was a really significant achievement for us. It may be a surprise to others, but we saw it coming."
No country has nailed down all 14 spots at Rio yet. Britain are closest with 12, missing only the women's singles and quad. The United States have 10, Germany nine.
None of the crews are there for the ride. "We wouldn't be sending these five crews if we didn't believe they had a chance," Peterson said. "We're not flipping a coin.
"It's a calculated programme behind all this with the sports science involved these days and we're looking forward to this weekend and being successful with all five crews."
Racing begins on the Rotsee course tomorrow night (NZT).
