Corrigan lives in Golden Bay, in the South Island, with his wife Ruth and their two sons. He is a partner and manager of the family’s dairy farming business with his parents and brother Sam.  
 
Corrigan is a graduate of Massey University with a Bachelor of Applied Science, was a former Consulting Officer with DairyNZ and a Farm Consultant with FarmRight, in Canterbury. 

As well as managing the 400ha dairy farming business, Corrigan is Chair and Independent Director of the South Island Dairy Development Centre (SIDDC), which operates the Lincoln University Dairy Farm. He is also Deputy Chair of the DairyNZ Dairy Environmental Leaders Forum, an initiative fostering environmental stewardship and community leadership amongst New Zealand dairy farmers. 

Farming practices that strengthen the integrity of the food produced is something Corrigan seeks to better understand. “How can we give our farmers better market signals about the value they are creating in their production systems, especially inside a large cooperative?”
