A dance crew from the Netherlands were named world champions, and two British crews placed second and third.
Ms Martin said she was "incredibly proud" of her young charges, who competed with 100 per cent commitment, passion, and huge pride on the world stage.
"These competitions are not just about winning titles, but it gives our dancers a huge confidence and morale boost, and also gives them great exposure to international choreographers and talent scouts, who can help open doors for them."
De Visu are the current Street Dance New Zealand's Bay of Plenty regional champions and National Hip Hop Unite Champions.
De Visu also competed at the 2016 UDO Street Dance World Champions in Las Vegas.
Ms Martin said De Visu members also attended a training camp in Germany attended by about 2200 students and many of the top international choreographers.
They also spent time training with America's best dance crew Kinjaz in Los Angeles, who also shared tips about making it in the industry, she said.
De Visu Dance Crew also performed at the gala opening of the 2017 Anchor Aims Games.
Ms Martin said next month eight of the crew members would head to Brisbane to compete among about 40 crews at the Australasian House of Champions competition.
