WATCH: Jaedyn Randell stuns with te reo Māori performance on 'Moana' World Tour

Māori singer Jaedyn Randell, who voiced Moana in both te reo Māori versions of the Disney film and its sequel, surprised the audience with a switch in language during a performance at a special 'Moana' event in Sydney on Thursday night.

She took to the stage looking the part of a Disney princess in a stunning floor-length lilac gown embellished with sparkling floral accents.

She performed a beautiful rendition of 'How Far I’ll Go' from the first 'Moana' film, accompanied by the award-winning Signature Choir, before seamlessly launching into the te reo Māori version from the second verse.

Our very own rova reporter, Monika Barton, was there to capture the moment.

"There was such an incredible sense of pride for all the Pacific cultures on display, but the Kiwis in the crowd lost it when Jaedyn started singing in te reo," she said.

She’s so talented, and it was such a thrill to hear her represent Aotearoa with such an iconic Disney song.

Dwayne Johnson also delivered a surprise musical performance at the event.

Members of Polynesian music group Te Vaka joined Signature Choir to perform 'You’re Welcome', Maui's iconic song from the first film.

Naturally, the crowd went wild as the song reached the rap section, with a very buff-looking Dwayne appearing microphone in hand to help bring the performance home.

Peep the mic drop at the end - he knew he crushed it!

Afterwards, Dwayne took a moment to share why the 'Moana' franchise is so close to his heart.

"The character of Maui was inspired by my grandfather, the late High Chief Peter Maivia, and that is so special to me. But also, I think beyond that, and much more important than that, we have a film that represents our culture… And that really means something," he said.

"We have worked together for over a decade now, bringing one, two, three iterations of 'Moana' to the world, and what I have felt going around the world with this film is a real global embracing of Polynesian culture, and that is special."

That is something you can all be proud of... because it's a shared culture too. We have values, and we have anchors in our culture about pride, respect, loyalty and service for our culture that are shared among cultures around the world.

"Unlike any role that I've had the honour to play, this one is different, this one hits home, this one is special because, yes, my grandfather, but more importantly than that is our culture and what that means."

The actor also thanked music producers Tiana Nonosina Liufau and Kayla Faʻamaligi, along with Te Vaka founder Opetaia Foaʻi, who collaborated on the music for the films and helped uphold Polynesian culture throughout the making of the 'Moana' movies.

Elsewhere in his speech, Dwayne invited Helen from Signature Choir on stage to share a special backstage moment they had together.

While chatting backstage, Helen told Dwayne about watching his grandfather wrestle on the New Zealand TV show 'On the Mat'. She explained that seeing him on screen was an exciting moment of representation for Samoan people.

"It got me emotional," Dwayne said.

After all these years, my grandfather would have had no idea that years later, here we are with this big movie, putting our culture on the map!

And that's not all! Keep an eye out for a very special interview between Monika Barton and Dwayne Johnson coming soon to rova - chee-hooo!!
