When Volker Kuntzsch stepped down from his position of CEO at New Zealand seafood giant Sanford last month, he took a break from a 30-year career that has seen him work on five continents for some of the fishing industry's biggest names: South African harvester Sea Harvest, former Unilever company Frozen Fish International, Namibian group Hangana Seafoods and Japanese giant Nippon Suisan Kaisha (Nissui) among them.

With a strong focus on the importance of people -- evidenced by the praise current and former colleagues tend to heap on him -- Kuntzsch has made cultural transformations all along the way.
