He has a wide and varied range of business experience, including working in the meat industry, at Mars Petcare and as a contractor for Ngā Rauru.
"But I wanted to upskill, so I decided to come back to study."
Mr McGregor is no stranger to study - "I'm always taking every opportunity I can to upskill" - but this is the first time for a long time that he has taken on study full-time. He's enjoying the experience, although it can be challenging to juggle his studies with full-time single parenting of three children.
"It's good to take some time off and soak up new information," he said.
After he graduates next year, Mr McGregor hopes to go on to do a bachelor degree in business, most likely at Massey University, and may one day open his own business.
"I'm majoring in management and accounting, so I'm keeping my options open."
Mr McGregor attended the scholarship ceremony on Wednesday evening, and was able meet with the donor of his scholarship.
"I feel very fortunate to receive this scholarship. I feel very humbled - there are many UCOL students who would be worthy of it."
