However, she has since become a successful model and a social media icon.
Miss Arkle, known as Rosie, has 1.2 million likes on Facebook, 400,000 follows on Instagram and 16,000 followers on Twitter.
"I think it's been the main ingredient in building my brand," she said of her social media profile. "Without that, I don't think I would have all the work I have today."
"It's just a really good way to connect with people that follow you."
The only slight negative of the billboards, which will be up for three weeks, was her first name was spelt wrong - with just one "n". The creative director of Maneater said the billboards were done in collaboration with 138WATER and naturally they felt terrible about the mistake.
Her father Brady Arkle, who works for NZME. in Whangarei, said that despite the error the billboards were awesome.
Between himself and her mother, their daughter was raised in front of a camera, Mr Arkle said.
"We created a monster," he joked.
Mr Arkle said he was proud of how she had used tools like social media to further her career.
"She's always known her own mind," he said. "She doesn't suffer fools."
However, when the Northern Advocate asked Miss Arkle her key to success, her answer was a lot more simple: "I guess I just go with the flow and awesome opportunities happen."
