Three Māori contestants have made strides in The Voice Australia, each advancing to the semi-finals and showcasing their talents on a national stage.

Jaedyn Randell (Waikato), Jaydin Shingleton (Ngāi Tahu), and Letitia Butler (Ngāpuhi) are among the top eight contestants vying for a place in the finals this weekend.

Ms Butler is competing on LeAnn Rimes's team, Shingleton represents Guy Sebastian, and Randell is on Kate Miller-Heidke's team.

Mr Shingleton described his experience on the show as surreal, especially with his whānau (family) present.

"It was amazing to have them all there, including my mum, who's been like my teacher from the start," he told RNZ.

"As I walked out on stage, I could see my family to the left, and I could feel my eyes welling up."

He expressed pride in representing his Māori heritage and noted the significance of his whakapapa (ancestry) in his journey.

"I am definitely proud to be Ngāi Tahu, Māori from New Zealand for sure," he said, adding that he made sure his pounamu was visible during his blind audition.

"I haven't had a lot to do with my culture, and that's something that I want to do in the future."

Ms Randell, who is also known for voicing Princess Anna in Disney's Frozen and Moana, is one of the youngest contestants at 22.

She said her experience in voice work has bolstered her confidence.

"Voicing a character really translates into my performance because they can't see your face behind th cartoon, so everything needs to be portrayed with your voice," she said.

"Music means the absolute world to me.

"I feel like that's what I was meant to do."

Ms Butler turned two chairs during her audition and faced tough competition as the selection process neared its end.

In her audition video, she admitted to feeling pressured and nervous about not advancing.

"Singing to me is my life, but it's really hard for me to believe in myself. I've had so many setbacks," she said.

She credits her whānau for encouraging her to audition, recalling a conversation with her husband about the opportunity.

"With no hesitation, he said 'Mama, anything is possible," Ms Butler said.

"Him knowing that I would never seriously do anything like this for myself without my whānau being part of it gave me all the permission I needed to shift my mama mentality and submit the audition form."
