Each BrewKeg 50 is assembled at the company's Hastings factory. General manger Jeremy Absolom said, while the team had been "quietly confident" about winning the award for Most Innovative New Equipment, they had been stunned to also receive the overall prize.
"It was a surprise, but it was certainly a just reward for our two directors who have been tirelessly working away."
While the equipment was only test marketed earlier this year, he said it was quite an exciting time in the food and beverage area.
"People are looking for points of difference, they're looking for locally made, fresh food and fresh beverages, that's where our product sits," Mr Absolom said.
"We're enabling restaurants and bars access to brewing capabilities that historically have been beyond their reach.
"Restaurants can be creative with food and menus, and build their brand that way, but until recently they haven't been able to do that with their beverages."
North Port Events CEO Dona White said choosing the winners proved difficult due to the high calibre of entrants.
Held every two years since 2010, Fine Food New Zealand is an international trade event for the food service, food retail and hospitality industries, with this year its biggest yet. Fine Food New Zealand, run by North Port Events, recognised the country's unique selling position as an innovator in the entire culinary field, Ms White said.
