Miss Whitewood was exceptionally proud to see Maori design in the limelight.
"I entered because I am passionate about seeing Maori design elevated to a high-end sort of couture arena."
Miss Whitewood graduated from AUT in 2009 with a bachelor of design and successfully launched her own label, Kimihia He Ngaro, which means search for the unseen or unobtainable, in 2010.
She now has an online business and also sells her work through her Facebook page. She plans to use her prizemoney to launch 700 new pieces with another local designer, Amiria Skipworth, at the upcoming Te Matatini Kapa Haka Festival.
Model Stevie Rowley, 20, who also did the hair and make-up for Miss Whitewood's other models, said she loved strutting down the catwalk in her friend's designs.
