Lynette Fisher, with her work titled My Friend Awhina, 1981, won the Ethel MacMillan Award and received $250 prize money.
The Incubator Emerging Artist Award, a new award this year, was presented to Isaac Crowe for his work titled Angela of Makawe.
Crowe's prize for winning was the opportunity to exhibit at the Incubator Gallery.
This is part of the Incubator Creative Hub initiative titled First Solo, an emerging artists exhibition series.
Awards judge Nigel Borell said he was impressed with the diversity, vitality and brilliance of the more than 100 entries for the 2018 awards, 39 of which were chosen as finalists.
"The pursuit of excellence and quality is surely one of the goals for any artist and there are some outstanding examples of this idea in the 2018 nominees."
The final award, the Bay of Plenty Times People's Choice Award, will be presented after the exhibition closes and public votes have been counted.
Members of the public will be able to vote for their favourite artwork during the exhibition which runs until September 2.
All selected artworks, if not already pre-sold, can be bought from the gallery.
Tauranga Art Gallery Director Karl Chitham said: "This year we had a huge range of entries in terms of materials, scale and subject matter, which really shows the sheer number and diversity of artists we have working in the Bay of Plenty."
