Honestly, when everyone started buzzing about the Moana 2 trailer, they were all over Maui’s tattoos or the new villain. But if you really look at what makes this sequel tick, it’s the family dynamic back on Motunui. Specifically, we have to talk about Sina.
In the first movie, she was the "supportive mom" who mostly kept things together while Chief Tui was busy being overprotective. But in the Moana 2 cast, Nicole Scherzinger’s return as Sina feels a whole lot weightier this time around. Why? Because the stakes aren't just about one girl and a boat anymore. They're about a growing family.
Who is the Voice Behind Sina in Moana 2?
If you've ever heard Sina speak and thought, "Wait, that voice is way too powerful to just be a Disney mom," you're right. It's Nicole Scherzinger. Most people know her from the Pussycat Dolls or judging The Masked Singer, but she’s been a powerhouse in the West End and on Broadway (shoutout to her run in Cats and Sunset Boulevard).
Scherzinger is of Hawaiian descent, and she’s gone on record saying she practically begged to be in the first movie. She told The Mommy Factor in an interview that she didn't want to go home and have her family ask, "How come you’re not in Moana? You are Moana, Nicole!" She basically lived the life of these characters, growing up with her mother and her "tutu" (grandmother).
In the booth, she doesn't just read lines. She draws from the strength of the women in her own family—women she describes as the "backbone" of the culture. It’s that real-world mana she brings to the Moana 2 cast that makes Sina feel less like a cartoon and more like a real protector.

Why Sina Matters More in the Sequel
So, what’s different now?
In Moana 2, which picks up three years after the original, the world of Motunui has expanded. Moana isn't a sixteen-year-old dreamer anymore; she’s a nineteen-year-old leader. And Sina? She’s a mother of two.
The addition of Simea, Moana's adorable little sister (voiced by Khaleesi Lambert-Tsuda), completely changes Sina’s role. It’s one thing to let your only daughter go off on a "suicide mission" to save the world when the island is literally dying. It’s another thing to manage a household and a community while your eldest is constantly chasing the horizon, leaving a younger sibling behind who idolizes her.
The Sina and Simea Dynamic
- The Bridge: Sina acts as the emotional bridge between Tui’s fear and Moana’s calling.
- The Protector: She has to raise Simea in a world where "staying inside the reef" isn't a rule anymore.
- The Wisdom: With Gramma Tala gone (at least in physical form), Sina has to step up as the primary source of maternal guidance.
The Evolution of the Moana 2 Cast
While we’re talking about the Moana 2 cast, it’s worth noting how the ensemble has shifted to support this new family focus. We still have the heavy hitters:

- Auli'i Cravalho as Moana (older, stronger, and now technically a demigod-level leader).
- Dwayne "The Rock" Johnson as Maui (still Maui, still has the hook, still loves a good song).
- Temuera Morrison as Chief Tui (who has finally chilled out about the ocean, mostly).
But the new crew members like Loto the engineer and Kele the farmer show that Moana’s life is getting crowded. In all that noise, Sina is the one who keeps Moana grounded. There’s a scene where the family watches Moana set sail, and you can see the conflict on Sina’s face. She knows the ocean is Moana's destiny, but as a mother, the ocean is also the thing that takes her daughter away.
The Live-Action Crossover
Here’s a fun bit of trivia that messes with people's heads. While Nicole Scherzinger is the definitive voice of Sina in the animated world, she won't be playing her in the upcoming live-action remake. That role is going to Frankie Adams (best known for playing Bobbie Draper in The Expanse).
It’s an interesting choice because Adams is known for playing "tough-as-nails" warriors. But if you think about Sina’s character, she is a warrior in her own way. She fought for her daughter’s right to choose her own path. She kept the village running.
What This Means for Your Moana 2 Rewatch
If you’re planning on sitting down with the kids (or just a bowl of popcorn by yourself, no judgment), keep your eyes on the background characters. The Moana 2 cast was built to show a village that is thriving, and Sina is the heart of that progress.

Listen for the nuance in Scherzinger’s performance. There’s a specific "sharpness" to Sina in the sequel. She’s playful and strong-willed, but you can hear the worry of a mother who knows the world is much bigger and more dangerous than her daughter realizes.
Actionable Insights for Fans:
- Pay attention to the music: The soundtrack involves Opetaia Foaʻi and Abigail Barlow/Emily Bear. Listen for the "family" themes; they usually center around Sina’s presence.
- Watch the eyes: The animation in Moana 2 uses new tech to show muscle movement and micro-expressions. Watch Sina’s face when Moana talks about the "lost island"—it tells a story the dialogue doesn't.
- Look for the sisterly bond: Simea’s behavior is basically a mirror of Moana, but Sina’s reactions to them show how much she has grown as a parent.
The real magic of the Moana 2 cast isn't just in the big names like The Rock. It’s in the way characters like Sina provide the emotional stakes. Without a home worth coming back to, Moana’s journey wouldn't mean half as much.
Go back and watch the scenes where the family is together on the beach. You’ll see that while Moana is the one steering the boat, Sina is the one who made sure she had the strength to hold the oar in the first place.
Next time you see Nicole Scherzinger on a red carpet, remember she’s not just a pop star—she’s the voice of the woman who keeps Motunui from falling apart. That’s a pretty big deal for a "Disney mom."
