In its 16th year, the Young Viticulturist of the Year competition consists of six regional finals, focusing on core industry skills.
Central Otago organiser and 2011 national winner Nick Paulin said the competition was an opportunity for young people involved in viticulture to stretch themselves and their skills, as well as build relationships with others working in the industry throughout the region.
"Part of the competition is as much about education as it is about competing for a prize, so we're trying to teach these young guys and girls some new skills that will help them in their career," he said.
In a first for the competition, seven of the eight Central Otago contestants were female.
National organiser Nicky Grandorge said this was a reflection of the competition nationally.
"Generally this year we've seen more women step up into the competition and I think it really does highlight it's an exciting industry for men and women," Grandorge said.
Jackson will be the fourth woman out of six to compete in the 2021 Young Viticulturist of the Year national final in Blenheim next month - in a first for the Young Viticulturist of the Year competition.
The national winner will also represent the wine industry in the Young Horticulturist of the Year competition in November.
