Since then she has been an entrant in the Miss Teen Hawke's Bay pageant and competed at the World Championships of Performing Arts in Los Angeles as a singer and model.
Support from Hawke's Bay people and businesses had seen her come a long way and given her confidence to continue.
Over the years she has learned a lot from performers with more experience and through singing at church but wanted to be totally ready before taking the plunge on national TV.
"I haven't specifically been wanting to audition for X Factor but I have been preparing myself for a big event like that for the past two years, that's why I didn't audition for the first one - I didn't think I was ready then."
While she was unable to give too much away before the first episode airs from 7pm this Sunday, Mrs Lewis did say the audition process was a scary but amazing experience.
One thing you won't hear is an original or anything with a sad undertone. Her belief is that music should be uplifting and appeal to all ages.
"It was a big decision because I think not everyone auditioning quite understands you're not just singing for the judges and people in the room, you're singing to Aotearoa.
"I think it's important to sing a song that will captivate and move them and make them happy."
Before the 2015 series went to air, she encouraged people to realise the amazing talent not only on stage but behind the judging panel.
"I think everybody likes Stan Walker the best because they don't know the other judges. It's important to give them all a chance. Stan, he's a hero, he's come to New Zealand before but everybody should try to research all the judges. Natalia Kills writes for Madonna, that's incredible."
