Ms Cassidy said winning has already started opening doors and she has been flooded with offers, but says her long term plans involve a career selling real estate and in property development.
Ms Cassidy's win is another one for the family album. Her mother Michelle Betts placed fourth in the same event in her 20s. Miss Betts, a Bay of Plenty Times media sales consultant said: "I'm absolutely thrilled. Holly has worked so hard from the get-go for this and she deserved to win. She is a real Kiwi girl at heart who is not only beautiful looking but she is lovely with people and her great personality shines out."
As well as the sought-after title Ms Cassidy won over $10,000 worth of prizes including a Versace watch, onyx ring and earring set and a Suzuki scooter. She will also be signed up to top model agency Nova Models in Auckland.
Miss Tan, 23, said: "I'm very pleased and proud to be first runner-up as there were some stunning girls competing, and it's very exciting to be offered a modelling contract with Nova Models.
"It's one up for us shorties," she quipped.
For the first time in 20 years, the event was televised live on Juice TV and the winners were picked partly by public text votes and partly by the judging panel.
