As the comical scene unfolds, director-general of health Ashley Bloomfield's face appears in the background, replacing a female aide from the film.
It ends with Bloomfield smiling with glee as the number 0 is highlighted in a government "United against Covid-19" poster.
The final scene pays homage to when Bloomfield revealed that even that though he is "not quite as good a dancer as the prime minister", he did allow himself "a little smile" when he heard the news.
People have praised the hilarious parody on social media.
"This is just brilliant. Bravo. Haha," one person wrote.
Another added: "She is a better prime minister than Hugh Grant."
While another wrote: "This is brilliant. Made me laugh soooo much. Such an amazing piece of art that makes the world laugh. Big thanks to the creator!!"
