Fonterra is creating two new management roles to increase focus on innovation and driving strategy.
Daly joined the co-operative earlier this year as director HR chief operating officer (COO) and as a member of the people & culture lead team.
Fonterra CEO Miles Hurrell says COO is the engine room of the co-op with around 12,000 employees in manufacturing, supply chain, innovation, IT, sustainability, technical excellence and global quality and safety.
"Kate has hit the ground running and has already made a difference during an important time as the co-op has continued to deliver on its strategy at a time of significant global uncertainty.
"Kate is an experienced people leader and is passionate about creating the environment where people can develop and thrive and where inclusion and diversity is a key focus.
"We are very lucky to have someone of Kate's calibre and experience and I'm looking forward to her contributing to the co-op in her new role."
She will report to Hurrell and will be a member of the Fonterra management team.
