"Instead, the Pumphouse served New Zealand red deer tenderloin."
The meat claim was found last August to be in violation of state and federal law by the Department of Environmental Conservation. It ordered the restaurant to correct its menu.
As well as the US$50,000 fine, owners of the Pump House also donated US$10,532 to three charities.
Pump House owner Vivian Bubbel refused to comment when contacted by the Weekend Herald.
"It's just radio silence,' she said.
"We're not talking about this at all under any circumstances."
Deer Industry NZ chief executive Dan Coup said although the US was an important market for Kiwi venison, he did not think deer farmers would be too worried about the case.
He said it was "sad" top New Zealand produce had been mislabelled, adding many top restaurants in the US were "proud to have grass-fed New Zealand venison on the menu".
"I really think this would be in your 'quirky anomaly' category," he said.
"Farm-raised venison is a pretty expensive, high-quality product so it would be unusual for it to be passed off as feral reindeer.
"This incident is possibly driven by the restaurant having a 'local' theme in its menu."
