The rise of the quintessential Kiwi coffee began in the US a few years ago but New York magazine placed the credit squarely with the Aussies.
"Although available in New York's few Australian restaurants and meat-pie shops for at least a decade, it has grown in prominence with the rise of our coffee culture," the February, 2012 story said.
But the rollout by Starbucks has been met with scepticism by some stateside.
US website Vox responded to Starbucks' announcement with a piece entitled: "The flat white is Starbucks' attempt to get more respect from coffee snobs."
It said the company had been "classing up its act in the last year or so, trying to appeal to coffee snobs and not just busy workers looking for a caffeine fix".
Regardless of Starbucks' motives, the move is likely to find favour with ex-pats keen for a taste of home.
