"We're prepared to fight for what we think are the principles of trade," said ambassador to Indonesia Trevor Matheson. "These are not just principles that we have chosen out of the sky - these are principles that Indonesia accepted by becoming a member of the WTO."
NZ has a free-trade agreement with Indonesia through its combined FTA with Australia and the Association of Southeast Asian Nations, which came into force in 2010.
The import restrictions have hit the wallets of Indonesian consumers.
"The price of beef here is double the world price," Matheson said. "We've made those representations to Indonesian ministers and officials that it's hard to understand how such policies benefit their own people."
Indonesian Trade Minister Rachmat Gobel lost the portfolio this month after outrage over the price spike. His successor, Thomas Lembong, has indicated beef imports could rise, but only "if necessary".
New Zealand's Trade Commissioner in Jakarta, Tim Anderson, said previously strong exports of beef offal products to Indonesia had been a "game-changer" for Kiwi exporters. However, the import restrictions had made companies wary of the country, he said. New Zealand exports to Indonesia were worth $886 million in 2013.
