Ms Milne has served as the West Coast president and a national board member, as well as being a member of the National Animal Welfare Advisory Committee and Farmer Mental Wellness Strategy Group, chairing the West Coast TBfree committee and setting up Lake Brunner environmental projects.
She was named Dairy Woman of the Year and a Rural Woman of Influence in 2015.
Ms Milne said she would have to spend a bit more time away from the farm as the federation's president, but she was already used to travelling to Wellington for board matters. She also went to Auckland last year to participate in the Global Women ''Women in Leadership'' programme, which was part of her Dairy Woman of the Year prize.
She had a ''grassroots style'' she hoped would encourage more farmers to sign up as federation members, Ms Milne said.
Signing up was more important than ever, with the ''social licence to farm'' being attacked again by people from outside the sector, she said.
