Genetics

Headwaters is a producer group that supplies premium New Zealand lamb through their own brand Lumina Lamb. The 95 farmers in joint venture with Alliance Group breed sheep that deliver genetics, performance, and premium eating quality from hill country to plate.

In this episode, Headwaters CEO Steve Brown and Breeding Manager Tara Dwyer join Jo Scott to discuss how genetics, collaboration, and market connection are driving value across the Lumina supply chain. They explain how a science-based approach and close farmer–chef relationships are building both a stronger breed and a trusted premium brand.

A shared drive to improve genetics is at the heart of the Shedding Sheep Improvement Group, where breeders nationwide are working together to lift performance and reduce workload in shedding sheep.

In this episode, Daniel Wheeler, Group Manager of the Shedding Sheep Improvement Group, joins Jo Scott to discuss how a collective of breeders is driving genetic progress for shedding sheep across New Zealand. He explains how the group’s collaboration, sharing data, genetics and ideas, is helping to lift performance and reliability in this fast growing sector.

A focus on dual-purpose genetics is at the heart of Romani Farms, where Ross and Ruth Richards run 700 hectares in the King Country.

In this episode, Jo Scott talks with Ross about breeding resilient Coopworth and Wiltshire flocks built on decades of selection for facial eczema and worm tolerance, structural soundness, and low-input performance. He reflects on their progress, the transition to maintenance-free Wiltshires, and how balancing data with practicality has produced robust, high-performing sheep suited to real-world farming conditions.

Focusing on shedding composites has reshaped farming at Waitohi Peaks, where Andrew, Sara, Digby and Guy Heard run stud and commercial flocks on North Canterbury hill country.

In this episode, Jo Scott speaks with the Heards about their shift to shedding composites, the workload and cost savings, genetic progress, and the opportunities they see for building more resilient and profitable sheep systems.

In this episode, Sarah Perriam-Lampp talks with Nuffield Scholar Rachel Baker about her research into the potential future of gene editing in New Zealand’s primary industries which formed the basis of her 2024 Nuffield scholarship. Rachel explored how New Zealand could responsibly adopt the technology while protecting its global reputation.

She highlights international models, like Norway’s, and sees early potential in horticulture. Emphasising transparency, trade alignment, and inclusivity, Rachel believes gene editing should be farmer-led and value-driven—supporting innovation while respecting consumer choice and the diverse values across New Zealand’s food and fibre sectors.

In this episode, Sarah Perriam-Lampp speaks with two professors with expertise in gene editing about New Zealand’s proposed gene editing legislation. Professor Jack Heinemann discusses why the concerns about the details of the Gene Technology Bill are crucial for the likes of Fonterra. He highlighted risks around traceability and the increased level of compliance for farmers and the potential limitations of trade access.
Professor David Williams, with his expertise in gene editing, warns of potential unintended consequences and GMO contamination, advocating for a robust regulatory framework to safeguard farmers and the environment. Together, they explore the need for careful oversight in the evolving field of gene editing at the Bill works through the submission process.
