She spent 12 years as a Rotorua district councillor, served nine years in two stints as a Bay of Plenty regional councillor, twice stood unsuccessfully for Labour in parliamentary elections, chaired the Mt Ngongotahā Restoration Trust and was involved in so many committees and organisations it was only fitting an MBE was awarded in 1995 to recognise her service.
She is described by her family as stubborn, loving and the glue that held them together. She was so stubborn in fact, she survived contracting the paralysing Guillain Barre syndrome in 2003.
She spent nine days unable to move and six weeks in Waikato Hospital before making a shock recovery that saw her describe herself in latter years in a Rotorua Daily Post article as a "walking miracle".
She was equally chuffed about bouncing back from hip and knee replacements - further adding to her "wāhine toa" status.
British-born, she trained as a nurse before marrying Alan Michie. They emigrated to Canada before moving to Rotorua in 1972, when they took up running a motor camp at Okawa Bay on Lake Rotoiti's shores, the site where the VR Rotorua Lake Resort now stands.
It was there Michie's community involvement began.
She once told the Rotorua Daily Post: "The day I saw Lake Rotorua's awful state I knew I had to do something to help."
She served on the district council from 1980 to 1992. She did two stints as a regional councillor from 1989 to 1992 and 1995 to 2004.
She also tried her hand at national politics, standing for Labour in the Rotorua electorate in 1987 and six years later the then Tarawera electorate.
Her hot topics to tackle were women's rights and the environment, including being instrumental in establishing Rotorua's recycling centre.
Her daughter, Jenny Michie, said her mother was diagnosed not long after lockdown began and they would hold a private cremation before holding a public celebration of her life once the alert level restrictions lifted.
"She was the ultimate matriarch and was the glue that kept us all together, especially after Dad died 21 years ago."
She said she would miss visiting her mother at her Mourea home, where she lived for the past 40 years.
"She was like a matriarch to the Labour Party movement."
Chadwick said she led the selection of local candidates and worked "hand in glove" with the late Johnny Lepper.
Michie was very proud of Chadwick when she won the Rotorua seat for Labour - a first for the party in 39 years.
"She was always very credible and well-researched. On the electorate committee you feared her views and she would take you on."
Chadwick said she found herself on opposing sides to Michie - a lover of the Rotorua library and former librarian - when she went head-to-head with the council in 2016 to try to stop the library health hub development.
She said it was proof Michie was about the politics, not the people.
"I said to her at the time, 'Rosemary, what are you doing? Do you really think I'll ruin the library?' but it showed me that we had to communicate better and it was a nudge from her. It was hard to be on the wrong side of her but I respected her.
"Rosemary was a lovely person and very elegant in every way. She always put things very nicely – but very determinedly."
Michie is survived by three sons and a daughter along with several grandchildren and great-grandchildren.
