Fonterra's group finance director Chris Rowe takes on the role of acting chief financial officer (CFO) from next month.
He replaces current CFO Marc Rivers who is leaving the co-op at the end of this year.
Rivers will move into the role of strategic advisor to chief executive Miles Hurrell from October 1 until his departure.
Hurrell says that Rowe has worked for Fonterra since 1988, undertaking a number of commercial and finance leadership roles.
“Chris is a highly competent leader, who has considerable knowledge of the co-op and the management of its physical and financial portfolios, as well as its mergers and acquisitions.
“The recruitment process for a permanent CFO is well underway and I hope to announce the successful candidate in the coming months,” says Hurrell.
