Other commenters asked if zoo staff realised Australia and New Zealand were two different countries and criticised them for failing to do their research beforehand.
The zoo responded on Facebook with a statement, saying Māori people were "native" to both nations, Stuff reported.
That comment has since been edited to say they received incorrect information.
"The various entertainment featured recently in Walkabout Australia is a preview of our upcoming event Summer Safari, which features entertainment from all over the globe. Again, our apologies," the zoo's statement said.
"As a New Zealander, I can confirm that statement is incorrect," commenter Jason Solomon said.
"Just plain ignorant, and offensive that you try to defend it," commenter John Schwager said.
"Change the name to Trump Zoo!"
