7. Mowbray Family – $1.9 Billion
Nick, Matt, and Anna, who are the purveyors of the Mowbray family’s $1.9 billion (NZD$3 billion) wealth, did not grow up in a wealthy household.
Their parents worked as a teacher and an engineer. Yet, an idea and a $20,000 loan from them created a fortune that has made them one of the richest people in New Zealand.
