McIvor won't be totally lost to the pork industry. He is going to head up Wellington meat family Prestons. McIvor leaves NZPork in mid-March and a recruitment process for his replacement is underway.
NZP board chairman Ian Carter says McIvor has had "an action packed tenure during which we've endured a global economic crisis and domestically the industry has had some big issues to work through".
"Championing the industry's strong environmental standing, progressing the animal welfare changes and maintaining the industry's disease-free status have been significant pieces of work and Sam has shown strong leadership and the ability to work effectively with farmers through to politicians in this process".
McIvor is also credited for helping improve product quality and drive consumer demand for locally produced product.
"There is no doubt that consumers are much more aware now of the 700,000kgs of imported pork coming into the country each week and they're looking for NZ grown labelled products," says Carter.
