The three finalists were selected from a shortlist of seven applicants, who were interviewed recently in Auckland by a panel of eight judges.
Shane McManaway, award judge and chairman of the Platinum Primary Producers (PPP) - the Australasian networking group behind the award - says it was a tough job for the judges getting down to the final three, but he was confident that they've selected some great future leaders.
"It is extremely heartening to see what incredible achievements are taking place by the under 35s in agriculture. Lisa, Thomas and Janet all display vision, leadership, and a true passion for agribusiness. We all came away from the interviews inspired by what they're achieving, and the opportunities they present for the future of our industry."
The Zanda McDonald Award, now in its fourth year, was set up as a tribute to the enormous contribution McDonald made to agri-business.
The three finalists will attend the PPP Conference in Taupo in March, where the 2018 winner will be announced, receiving a prize package to the tune of $50,000.
