Rod Slater - head of steak, sauces and other meaty matters at Beef + Lamb New Zealand - said the results of the research were quite interesting.
"For a data junkie like myself, this research is absolutely fascinating.
"I always held the belief that New Zealand-grown, grass-fed beef was simply too tasty to require sauce. However, what we are seeing is a fundamental shift in the Kiwi palate," Slater said.
For Amy Vu, who oversaw marketing for Wattie's Tomato Sauce, the results were no surprise.
"Of course we know many New Zealanders love our tomato sauce on their steak – It's a Kiwi thing," Vu said.
Not everyone is as enthusiastic about the combination however, with comments from outraged steak lovers joining the debate on Beef + Lamb's Facebook page.
"If you put ketchup on steak, you're just as bad as Donald Trump"
"Maybe the world keeps omitting NZ from maps because you guys are putting ketchup on steaks"
"If it's steak in a pie - yeah."
