From models to matrimony - Roxanna Zamani's designs are going places.
The award recognised the wedding gown creation which best combined tradition with innovation.
Her collection, "Incongruous", featured repeated and draped material, creating pieces with architectural structure softened by romantic form.
School of Fashion academic leader Margo Barton said the win was "fantastic".
"It's such a huge honour," she said.
Ms Barton attended the awards as a juror for the main prizes and judged the Otago Polytechnic Scholarship Award, presented for showing innovation in the use of material and methods.
The eight-week scholarship to study in Dunedin went to Dutch woman Marielle Van de Ven (25), a Royal College of Art, London, graduate.
Fellow Otago Polytechnic graduate Sophie Hardy also showed her collection, "Possession Obsession", at the awards, which caught the attention of "big fashion companies", including Swedish clothing and cosmetics brand H&M, Ms Barton said.
