Dr Donald Stuart Tustin PhD DSc

Scientist/Researcher

Growing up in Hawke’s Bay, Dr Tustin developed a strong connection to the land and the fruit-growing industry. His father, Ian Tustin, was a berry fruit grower, orchardist, and nurseryman, helping to foster an environment where curiosity, hard work, and practical knowledge were highly valued.  

As a student at Hastings Boys’ High School, Dr Tustin embraced learning and developed the foundations that would later support an outstanding scientific career.  

Following his schooling, Dr. Tustin pursued a career in agricultural and horticultural science. He worked as a research officer at Massey University before joining the former Department of Scientific and Industrial Research, later becoming a leading scientist with HortResearch and subsequently Plant & Food Research. 

Over almost four decades, Dr Tustin has made internationally recognised contributions to apple and pear production systems. His research has transformed orchard management practices and improved productivity, fruit quality, and sustainability for growers both in New Zealand and around the world. One of his most influential achievements was the development and advancement of innovative orchard systems, including the widely adopted Slender Pyramid tree management system and the groundbreaking Future Orchard Planting Systems programme. These innovations have significantly increased the efficiency and profitability of modern orchards. 

In 2003, he was appointed a Fellow of the New Zealand Institute of Agricultural and Horticultural Science, and in 2014 he received the AGMARDT Technology Transfer Award for his ability to connect scientific research with real-world industry outcomes. 

Further recognition followed in 2016 when he received the Joe Bell Trophy from the Hawke’s Bay Fruit growers’ Association for his outstanding service to the fruit-growing industry.  

Most recently, in 2023, Dr Tustin received the NZIAHS Jubilee Medal, the Institute’s premier award, recognising his outstanding contribution to primary industry science and his lasting impact on the horticultural sector.  

Dr. Stuart Tustin’s story reminds us that remarkable achievements begin with strong values, a commitment to learning, and a desire to make a difference. His work has benefited growers, strengthened New Zealand’s horticultural reputation, and contributed to food production worldwide.
