Jason Wyn-Harris is a man on a mission.
As the third-generation guardian of his family’s central Hawke’s Bay easy to medium hill country properties, farmed as Marlow Hills, Jason has high expectations for their future performance under his watch.
Electronic identification (EID) tags have been used since 2013 in the family’s Marlow Genetics Coopworth and Romworth studs, but Jason is taking it to a new level in his quest for breeding rams more resistant to internal parasites.
He and his wife Rosa are equity managers for the Wyn-Harris family’s two farms, totaling 300ha of grazing area and 50ha of production and native forests. The properties are only a few kilometers apart, in a region of the country renowned for its bone-dry summers, balanced by healthy soils and reliable early spring growth.
