Logan Dunning Beck and Oscar Gunn rounded out a good week for the New Zealand 49er squad by finishing sixth, backing up the fifth they achieved in Auckland, and Isaac McHardie and William McKenzie also finished in the top 20.
Micah Wilkinson and Erica Dawson achieved a breakthrough result in the Nacra 17 by finishing seventh and they will now hope that is enough to convince the Olympic selectors to hand them a ticket to Tokyo. The pair have been sailing together for little more than nine months and were 19th in Auckland in December.
They did it off the back of consistently solid scoring as more fancied teams stumbled in the variable conditions dished up off Geelong all week.
"We're super-stoked," Dawson said. "Going into the regatta we had no idea where we would end up and it's probably better than we could have hoped, so we're really happy.
"It's part of our Olympic trials so it was definitely an important one and we are just happy we did our best and left it all out there."
Gemma Jones and Josh Porebski were the next best of the Kiwis in 13th, with Liv Mackay and Jason Saunders 15th.
A couple of other Kiwis will be chasing medals tomorrow across town at the Laser world championships, where Sam Meech is eighth and Tom Saunders 10th.
Germany's Philipp Buhl and France's Jean-Baptiste Bernaz continued to excel but with three gold fleet races still due to be sailed it's all still to play for.
Burling and Tuke can at least take their foot off the gas momentarily and reflect on another exceptional week that saw them win seven of the 13 races and confirm their position in the pantheon of Olympic class sailing.
"We've put in a lot of work over the last couple of years towards this Olympic campaign so it's definitely nice to see it all come together," Burling said. "It's a pretty key event. It's one that everyone tries to perform at so we are really happy with how we are progressing. It's just really exciting to wrap up another world champs."
Their attention will now switch to the Tokyo Olympics where the pair will be looking to defend the gold medal they won in Rio.
"It's an exciting few months coming up, that's for sure, but we will enjoy this," Tuke said. "It's been a great week. Obviously the result is great but the fashion we have done it has been pretty pleasing, too."
