When McKenzie was appointed director of the Manawatū Museum in 1978 she engaged local Iwi (
Māori: tribe) as kaitiaki (Māori: guardians) of the museum. Contrary to prevailing museum practices of the time she pursued a philosophy of 'keeping the taonga (Māori: sacred objects) warm.' This approach facilitated access for source communities to the museum collections including touching and wearing items of significance. By 1980 McKenzie had already established herself as an advocate for a new kind of bi-cultural museological practice. , at a graduation ceremony at the Regent Theatre, Palmerston North, in May 1998 McKenzie was a member of the
Te Maori committee. She was instrumental in having the North American tour extended to the
Field Museum in
Chicago. McKenzie was a mentor to many young people who went on to become prominent museum and heritage professionals and scholars in New Zealand. Throughout the 1980s, she utilised funding from government work schemes to employ students and Māori and train them in museum practice. McKenzie was instrumental in the establishment of a museum studies programme at Massey University, where she was an honorary associate professor from 1990 until her death in 1997. == Awards and honours ==
