The competition has attracted about 75 entries from 45 potters, the furthest submitted by Jane McCulla from Lyttelton and the bulk of entries from the Whangārei district as well as Auckland.
The event is being judged by prominent Auckland potter Peter Lange, a winner of national awards as well as recipient in 2016 of the NZ Order of Merit for his services to ceramics.
The winning works will be announced tomorrow at the Quarry Arts Centre's Yvonne Rust Gallery and entries will be on display there from August 25 to September 10.
The inaugural Quarry Arts Centre Open Ceramic Award on Friday marks the end of an era, with manager Ali Goodman's resignation and Sally Lush taking over the role.
Goodman said the ceramic award is the highlight of her two-and-a-half-year tenure, followed by overseeing this year's Great Plate fundraiser and overseeing building of the quarry's new wood fired kiln last year.
This year's Great Plate event raised more than $18,000, up from last year's second best figure of $7000.
Northland Craft Trust chairwoman Kate Smedley said Goodman had taken the Quarry Arts Centre to the next level.
