"It's about the people.
"It's about offering the pathways for people to achieve. You lay the pathways for them to achieve what they want, not what others want for them."
Recently Mr MacGregor has been a contractor with Ngati Pahauwera Development Trust, and has developed the delivery of the River Restoration project for Mohaka, Waikare and Waihua rivers.
His career before this included holding various positions within the Department of Māori Affairs including as Manager Housing and Land Development, Assistant Director Community Services and Housing, and Senior Housing Manager and Director Employment and Training through the 1970s and 1980s.
He was also a regional manager with Te Puni Kokori between 1990 and 2004 for both Takitimu and Wellington regions.
He developed the Joint Working Agreement between the then Ministry of Agriculture and Forestry and Te Puni Kokiri and worked with Manaaki Whenua on local and regional projects.
Then from 2005 to 2012, Mr MacGregor was strategic manager, Māori and Tagata Pasifika for the Agriculture Industry Training Organisation.
During this time he designed the Industry Training Organisation's Māori Strategy from scratch and assisted with embedding this strategy throughout the organisation.
He was involved in several initiatives including the Te Kuiti Māori Farm Managers Diploma and the development of the Ahuwhenua Young Māori Farmer competition.
Although there were a number of proud moments over his career, developing the young Maori farmer competition had been his most recent "great achievement".
"It's about people in farming, it's about young people, it's about contributing to Aotearoa New Zealand," he said.
"I think it really reinforces that contribution that Maori have, and will continue to make to the economic climate of this country. It signals to young Maori, and young people interested in farming that it's a career, not a job."
Mr MacGregor is also a trustee of several Ahuwhenua Trusts and is an advisor trustee to the Hinemanu/Ruaka/Te Upokori Charitable Education Trust.
