Presenters Profiles

 

Andrew & Jo Horsbrugh. MC and hosts.

Directors and owners of Tunlaw Farm walnut orchard.

Andrew and Jo started developing their 43 ha walnut orchard 21 years ago. They have planted 18 km of shelter, over 400 specimen trees, and 3615 walnut trees. There are four varieties of walnuts with the majority ‘Rex’ and ‘Meyric’ planted between 2003 and 2011.

Prior to starting the orchard, Jo spent 5 years working in the Food Service industry and has a Bachelor of Consumer and Applied Science from Otago University and a Diploma in teaching. Starting a family coincided with the purchase of their block of land in West Melton, and Jo has been full time on the orchard since 2000 while also bringing up the family.

Andrew has only recently come home to be full time on the orchard after a lifetime career in New Zealand agri-business. Andrew has had leadership roles at Farmlands Co-operative, Craigmore Sustainables, in manufacturing, and in the primary industry supply chain. These roles have ensured an understanding of New Zealand agribusiness from many different perspectives. Andrew is a member of the Institute of Directors and is Chair of Walnuts NZ Co-operative, a director of Donaghys Industries, and has sat on several other boards including 5 years at FarmIQ. Andrew has a BE (mech) and an MBA.
