Tuatara's volumes run at about two million litres a year and it is a leading light in the booming New Zealand brewing industry.
With sales growth continuing in New Zealand, Tuatara has cracked important export markets in Australia, Britain, Ireland, Scotland, China, Taiwan, Hong Kong, Singapore and Indonesia.
"New Zealand beer is hugely respected overseas and the Brewers Guild awards is a highly recognised international competition," Vasta said.
"That recognition is as important and sought-after internationally as it is here at home."
Tuatara won trophies (best in category) for best New Zealand lager (Mot Eureka), best pale ale (Sauvinova) and best wheat and other grain beer (Weiz Guy).
This year's Brewers Guild awards saw 946 beers from 98 breweries entered across 14 beer categories.
A total of 88 New Zealand breweries were entered in the awards, joining 10 breweries from Australia, Germany and the United States.
