Both were finalists last year, and enjoyed it so much they have dedicated months of their time to creating pieces for this year's event.
Ms Harray, a sculptor, said the event was a "good way of having a deadline", as it was easy for an artist to coast along.
It took her about six weeks to make her entry.
Her garment "Poly-Prop" is entered in the South Pacific section and is a skirt and corset made out of material woven like traditional Pacific Island mats, with a headpiece made out of steel in the shape of a nautilus shell.
Ms Harray said her inspiration came while she was living in Fiji for three months.
The garment was a symbol of the development of Polynesian nations as they modernised while retaining their sense of identity and culture.
Miss Quince said the idea for her creation came from an article in the Otago Daily Times World Focus section, about the revival of traditional voyages from the Pacific Islands to New Zealand.
Her garment, which is made from bamboo, wood, papier mache, fabric and string, is entered in the illumination illusion section.
She worked on her creation "on and off" for about three months.
Judge Suzie Moncrieff said the illumination illusion section was "very challenging" as artists had to create something that responded to ultraviolet light.
The show season runs from September 24 to October 4, in Wellington.
