Photos of the pair became viral on social media, with the heart-warming moments praised by Māori and touching souls around the world.
However, it soon became clear that not many around the globe were aware of what the pair were doing.
So a Twitter user took the time to explain what a hongi is: "It's a traditional Māori greeting where one acknowledges and shares te hā (the breath of life) by touching noses," they wrote.
"I'm so proud and happy to see Māori culture practised openly and shared .. at the Oscars!!"
The tweet went viral and made many aware that it was more than just a greeting.
And of course, Māoris and Kiwis were proud that Waititi had managed to share their culture with the rest of the world.
With this person's help along with the Hollywood pair's hongi, the rest of the world got to learn about an important piece of Māori culture.
