Malcolm Nicolson

Tumuaki – CEO

Born and raised on a farm in the small rural community of Warmbaths in South Africa, Malcolm emigrated to New Zealand with his family in 1996. They became New Zealand citizens in the Whare Runanga on the Waitangi Treaty Grounds on 1 January, 2000 in a special millennial ceremony.

Malcolm and Theresa have two children, and three grandchildren that are a source of great joy.

Strong family values and the quality of their home life are important to Malcolm and Theresa. They also place great importance on supporting and serving their community and this is reflected in their chosen careers.

Malcolm says, “I feel very fortunate that my role at the regional council allows me to contribute to the development of Northland. My wife, a qualified geneticist, retrained as a teacher for disabled children and now heads the Special Needs Department at Okaihau College.”

Malcolm and Theresa live at Hawkhill, near Kawakawa in the Bay of Islands area. They are preserving and conserving approximately two thirds of the 152 hectare farm, with a view to developing an ecotourism venture as a retirement project.
