The 23 year old loosehead is the son of Fijian front-row legend Joeli Veitayaki, who played 49 tests for Fiji between 1994 and 2003.
Hetet was born and raised in New Zealand but said it had always been a childhood goal to play for Fiji.
"Growing up I always supported Fiji, just because it was a part of me, and watching them play every game they play - whether it's rugby or other sports I would always back them," he said.
"It's just like being a Kiwi and backing every New Zealander."
