Courtney Flower, of Dargaville, won the intermediate event, turning the tables on regular northern shows competitor Alan Boler, of Wellsford, who a week earlier at Kaikohe scored at least his sixth win in the grade.
The junior winner was Kevin Welch, of Snells Beach, who does only one or two shows in the region each year and who is a brother of world two-stand ewes record-holder Sam Welch. He turned the tables on Ruawai's Hazel Wood, who beat him in last year's event at Warkworth.
With novice and veterans events, Warkworth attracted 26 shearers across the grades.
