Are you sure they're NZs wealthiest family? NBR has them at 3 billion and the Todd family (who are part of WelNix) at 4.3 billion. Both dwarfed by Graham Hart at 12 billion.
Edit: that was last years NBR, this year the Mowrays are worth 20 billion. Ironically they might be richer than Foley and that was astronomical growth compared to the previous rich list.
