"Costumes are a big part of it," says Giancarlo. "About 10 per cent is your presentation, that's your hair, your costume, your stage presence."
It's not surprising to discover the couple, who work, train and live together, have a habit of finishing each other's sentences. "As soon as you come on stage," continues Masha, who spent 10 years representing Slovenia in rhythmic gymnastics, "you've got to look like a champion, otherwise you won't be one."
Her exceptional flexibility is evident as she shares video footage from the duo's winning performance.
As well as competing, they are often asked to perform at salsa congresses overseas and were lead choreographers for salsa and Latin on New Zealand's version of So You Think You Can Dance.
"It was a really cool experience," says Masha. "Life's a lot different on TV. They want you to have some drama. They'd tell you, 'Step up the bitch factor' after lunch."
While the pair are in hot demand on the international circuit, it's their dedication to teaching others that's helped boost the profile of New Zealand salsa.
Giancarlo is originally from Peru and was introduced to salsa in Stockholm. From there he began a school in Melbourne before joining Masha in Auckland. The intention was to introduce a salsa-based syllabus which could be used throughout schools in New Zealand.
In their beginner class, they now have about 40 students; 23 in competitive teams. As is evident in the photos around the room, the dance form is not limited to the young.
"When we started out, there wasn't a lot happening here," says Masha.
"So when you consider New Zealand's a rugby nation, it's pretty good," adds Giancarlo, pointing out some blokes in sleek, bedazzled shirts.
Together the pair have produced some of the best salsa dancers in the country and on the world stage. "I got an email the other day from someone who's really high up in salsa in Australia," Masha says. "He said, 'You two are solely responsible for the growth of salsa in New Zealand'."
After finishing 15th in the previous world championships, in Puerto Rico, the pair are pleased with their latest second placing but would be stoked to take out the world title next time.
"It has just put wood on the fire," says Masha.
