Taika Waititi appeared on US talk show Jimmy Kimmel Live to promote his new film Jojo Rabbit, and he mocked the talk show host for his made-up nickname for New Zealanders.
He admitted to the talk show host there was "no real way to pitch" his latest movie, which is about a boy in Hitler Youth whose imaginary friend is Adolf Hitler.
"I'm from New Zealand, we're useless at pitching," he said.
Kimmel said: "The New Zealish aren't good at pitching, huh?" and Waititi wasn't a fan of the invented label.

Waititi gave Kimmel a disapproving look: "The New Zealish?"
"We're not good at knowing things about other countries," Kimmel said.
Waititi added: "Or words."
The filmmaker said he sent the script for Jojo Rabbit to various different studios, and after the success of Thor: Ragnarok, Fox Searchlight approached him to make the movie. There was one condition though: he had to play Adolf Hitler in the film.
During the talk show segment, the director confirmed his character Korg from Thor: Ragnarok will return in the Thor franchise's fourth installment.
He said: "My character's coming back, Korg." The studio audience erupted into cheers.
Thor: Love and Thunder is due for release in 2021, and Jojo Rabbit is released in New Zealand on October 24.
