After a buoyant month, dairy prices have fallen on the back of renewed concerns around a resurging Covid-19.
Brown is looking forward to leading the council for another 12 months. "I appreciate the support I continue to receive from councillors," he says.
The council has a new deputy chair; Duncan Coull was also elected unopposed and takes up his new role on July 29 for a 12 month term.
Coull was elected to the council in 2010 to represent the Otorohanga ward; he also serves as the chair of the council's representation committee.
He replaces Philip Palmer who is stepping down from the role after two terms.
Brown praised Palmer's contribution as deputy chair.
"Philip's support was incredibly valuable during what was a pivotal two years for the council and our cooperative and I thank him for his hard work and dedication.
"I now look forward to working with Duncan and am confident he will do a great job for the council as we continue to work to improve Fonterra farmers' returns through effective monitoring and strong representation."
