Her prize was tickets to the World of Wearable Arts (WOW) Awards Show in Wellington next month and a gift basket.
Deciding the winner must have been difficult, Mrs Harris said, because previous winner Laura Atkins' entry, silver and blue and titled Siren of the Tasman Sea, was also outstanding.
The awards took place in Bulls Town Hall. There were 26 entries in six categories, four for adults and two for children.
Child winners included Alannah Mullins' entry White Snow's Apple Fairytale, and Stella Beaven and Maia McKenna's Save the Seas.
The annual event included music and interviews, as well as viewing the clothing creations on a catwalk.
It was the first Mrs Harris had organised. She has been the town's community development manager only since mid-July.
"The hall was set out as a secret garden and it looked exquisite," she said.
She was also pleased to get lots of support.
"For my first time I had lots of amazing helpers that just got in and did it, and were still back here this morning helping clean up," she said.
