She is also chairwoman of major Maori land-owner Atihau Whanganui, Maori business development trust Poutama, and Taratahi Agricultural Training Centre, and is patron of Agri-Women's Development Trust, and a director of the family-based Paewai Mullins shearing and wool industry training offshoot Wool Systems. She has also been a director of Landcorp, a member of the Mid Central and Wairarapa district health boards, and of the Massey University council.
Her latest award comes after last year being made an Honorary Associate of UCOL while, in 2012, she was a member of Government's workplace Health and Safety Review Taskforce.
Mrs Mullins said one of the great things about New Zealand is being able to do what she does from her home town Dannevirke, her longest time away being when she followed the shearing with husband Koro around Australia for 14 months at the end of the 1970s.
They bought "about a hundred acres" on their return, and having run the shearing business for more than 25 years, now farm of about 120ha, with dairy cattle, and which has been farmed by Paewai whanau for five generations.
Asked how this led to the corporate board table, she said: "We were just brought up with it. My parents and grandparents were businesspeople ... It was what you did."
"The landscape has changed with the advent of Maori asset management, we are talking really serious assets," she said. "What comes with that is the opportunity to be awesomely positive, and be a really constructive contributor to the New Zealand GDP."
"This week's quite a nice week," she says, thinking of the diary of events.
"There's been a meeting with Merino NZ, continued launching of Wool Systems' new wool harvesting training app, a meeting with a honey collective "up north," and then a meeting of 2degrees Mobile, its chairman in the US, other members in the UK and Europe, and one in Dannevirke.
"I might just teleconference that one," she said.
