Fonterra Co-operative Council chair James Barron is stepping down after three years in the role.
Barron, who represents South Waikato on the council, retires by rotation this year and isn't seeking re-election.
He will hand over to a new chairman, to be elected by the 25 councillors, at Fonterra's annual meeting in early November. A new councillor for South Waikato will also be elected at the annual meeting.
Barron told Rural News that he was confident now was a good time to step down and hand over the reins to someone else.
"I'm confident now is a good time for succession to happen," he says.
"There has been a lot going on in the co-op over the last few years. Now we are in a period of relative stability and that allows me to step back and focus on other areas."
