Episode 82 – Bruce Thorrold on change
Bruce Thorrold sees a wave of scientific opportunity on the horizon, with breakthroughs in methane reduction and genetic innovation set to reshape the future of New Zealand dairying.
In this episode, Anne Lee speaks with Dr Bruce Thorrold, DairyNZ’s former Chief Science Adviser, as he reflects on his career and his move into semi-retirement. Bruce shares insights from his recent presentation at the NZ Institute of Rural Professionals conference, describing a “wave of opportunity” ahead for New Zealand dairy through innovations such as methane vaccines, inhibitors, boluses and high-lipid ryegrass.
He highlights that for new technologies to succeed, they must not only work technically but also be underpinned by viable business models and gain acceptance from consumers.

Bruce Thorrold talks about gene technologies, how the challenges of coexistence between GM and non-GM farming could be managed, and the importance of robust stewardship. He says lessons from international examples can help shape approaches in New Zealand, ensuring both farmer choice and market assurance are achieved. He also reflects on two decades of research leadership, from improving fertility breeding values and advancing genetic gain to driving plantain adoption and nitrate leaching solutions, all underpinned by close collaboration between scientists, farmers and industry.
Looking ahead, Bruce is excited about the role science will continue to play in balancing productivity with environmental responsibility. He emphasises the importance of teamwork across research organisations, agribusiness and farmers in turning promising ideas into practical, effective solutions for the sector. As he steps back from leadership, Bruce remains optimistic about the sector’s ability to adapt, innovate and thrive in a rapidly changing world.
