Courtney's award-winning artwork focused on creating tonal range and depth through the use of black and white mediums such as acrylic, oil paint, charcoal and ink.
An exhibition of finalists and winners' artworks at Tauranga Art Gallery closes on August 12.
Exhibition manager Duane Moyle earlier said about 100 entries were whittled down by the judging panel to 40 finalists.
Moyle said there was a huge variety of works in the exhibition, and the entries showcased a wide range of art mediums, including paintings and installations.
"Some of the artworks are quite challenging but others are more traditional. There is definitely something for everybody and the artworks are for sale."
The other category winners were announced on March 13.
Israel Randell was named the Supreme Award winner for her work Wahi Ngaro, 2019 - a striking installation of electroluminescent wire.
The 2020 Miles Art Awards is made possible by the Venetta Miles Trust, The Incubator and the Friends of Tauranga Art Gallery and the Bay of Plenty Times.
