She said she loved her new Wild West get up including spotted cowgirl vest, black stetson and fetching pink neckerchief.
"It's the right size and it's really, really, pretty cool."
Hinetaapora has had to sit on the news since Wednesday, when her parents let her in on the secret. It was one of the hardest things keeping it close to her chest, she said.
Her father Eric, was in Wellington with her yesterday. "Ever since she's found out she's been an uncontrolled bundle of energy, she's been fizzing."
Fluent in te reo and learning Spanish, Hinetaapora said she loved singing and kapa haka.
Hinetaapora will star in the new television commercial early next year.
Milkybar spokesman Jeremy Boucher said Hinetaapora, who received 11,000 votes, was a special youngster.
