While other 18-year-olds might celebrate with a glass in hand, Sophie will pass the milestone in no ordinary fashion, when she joins her All Black heroes in the captain's run in Dunedin today, before the test against the Springboks tomorrow night.
During the last few years the Gibbston girl has come out of her shell, achieving what even her mother, Bridget Newbold, never thought possible.
"The lovely thing about being down here [Queenstown] is she is a mascot in a way ...everyone knows her and that's the great thing about small-town Queenstown."
"Everyone is always giving, and Sophie has gained all the confidence. She is able to do a whole lot more here."
Sophie was born with cardio-facio-cutaneous (CFC) syndrome, a rare genetic condition that typically affects the heart, facial features and skin.
It is estimated there are only 200-300 affected individuals in the world.
The Newbolds moved from Wellington in 2000 when they purchased their winery near Gibbston, Gibbston Back Road Wines.
Since then, Sophie has ticked off much of a list she wanted to achieve before turning 18.
This included modelling with New Zealand's Next Top Model judge, Colin Mathura-Jeffree in Auckland, winning three gold medals at the Southland secondary School swimming ribbon meet last year, learning to ski (and quite competitively), learning to drive (in a $65,000 RCZ Peugeot), and today she will meet her All Black hero, Richie McCaw.
"I'll be a little nervous," she said.
So now that Sophie has hit adulthood, she wants a job.
Her expertise is most certainly in cooking and baking, she says, but she also has a big interest in animals and is looking towards helping out at the local vet.
Mrs Newbold says Queenstown has provided a real "safe haven" for her daughter, where people have fully immersed her in the community.
"There is always so much talk about this town as negative. There shouldn't be. There is so much positivity going about here. The people are caring, they're accepting."
"It's not in the fast lane here. It's quiet, we're happy and we're content. You get none of all that business of the city. It's good wholesome fun here."
Since moving here, Sophie's family has extended to Cure Kids Queenstown manager Josie Spillane, who has played a huge role in making the Cure Kids ambassador's dreams come true.
Miss Spillane has been behind Sophie's introduction to her favourite All Black Colin Slade, taking a ride in a helicopter, driving the car, and her time on the catwalk.
While Sophie's next accomplishment is anyone's guess, Mrs Newbold says their home is decidedly Queenstown for a good while yet.
"We have no reason to leave.
"It's nice to feel like you've got a rock."
