Meat company Anzco Foods has recorded a $60m-plus profit turnaround for the 2019 year.
He is as one of two processor-exporter representatives nominated by the Meat Industry Association (MIA).
Clarkson replaces Sliver Fern Farms chief executive Keith Cooper who resigned earlier this year calling the BLNZ ineffective.
BLNZ chairman Mike Petersen has welcomed the addition of Clarkson to the board, noting his considerable industry knowledge and experience in both sheepmeat and beef processing and marketing.
Before beginning his current role with ANZCO Foods Ltd in March 2004, Clarkson headed of ANZCO subsidiary CMP Canterbury Ltd for 10 years. He built strong relationships with customers, employees, shareholders and farmer producers.
In addition to the six farmer-elected board members, BLNZ has two processor-exporter representatives of which Clarkson is one and Craig Hickson of Progressive Meats is the other.
