Roberts has spent more than 20 years in the industry and was always working to find a better balance on-farm - environmentally and socially where they could "work the farm, not have the farm work us".
Award chairman Richard Rains said Covid travel restrictions had driven the change from one award winner to two last year but had also created an exciting opportunity.
The increase to eight finalists and two winners has a positive impact on more future leaders in Australia and New Zealand, he said.
"We're thrilled to be able to invest in the future of all eight finalists, and our two winners, and help with their future career and personal development.
"Our judges have again been overwhelmed with the level of talent and capabilities of this years' candidates, who have come from a broad range of backgrounds in the primary sector.
"They display a deep-seated desire to make a difference, along with ambition, personality and drive. We can't wait to meet the finalists face-to-face for interviews, and provide them with mentoring and media training as part of the process."
The Zanda McDonald Award recognises future young leaders working in agriculture and provides an impressive prize package centred around a tailored transtasman mentoring programme.
