"This programme will help these remote villages become more self-sufficient and improve the villagers' standard of living."
Safe chief executive Debra Ashton said Aucklanders would be shocked to learn their park was being used to raise animals for the controversial live export trade.
"Does the Cornwall Park Trust Board know for certain the conditions that they're sending their cows to?
"They'll face a long, rough journey in cramped, disgusting conditions before arriving at a country with high elevations and cold, dry conditions."
The trust board has been approached for comment.
Ashton said conditions in Mongolia would be "far different" from their upbringings at leafy Cornwall Park.
Many upset and disgruntled locals also made their views known on Facebook.
Many of those who commented said they did not support the live export of animals to other countries.
"Surely they have their own cows already in their country more suited to their climate and area. I don't agree with live exports," one woman wrote.
"Please do not do this," another appealed.
"It is an incredibly cruel journey and the Mongolian conditions are very cold and harsh - that's why the yaks there have so much hair! Ban live export."
Another said: "This is so sad, Cornwall Park. Is the few extra [dollars] you will get in the short term for these cows worth the suffering they will go through on board a ship?"
