Head judge Mark Wylie said the institute team stood out for their innovation and professionalism.
"Their dishes were innovative and contemporary and were to such an impressive standard that they could have been served in a top restaurant," he said.
The institute's head tutor, Jon Sefton, said it was great to see his team recognised for their hard work.
"We've been training since March ... tweaking and refining and we pulled a lot of late nights. The team have been hugely enthusiastic and dedicated."
The team's prize package is worth more than $7000.
Each member took home $1000, cookware and culinary products.
The institute, which is in Waipapa Road, also received a swag of prizes.
