Vintage said "If one is to believe the posters who have declared on this forum that it is not them - and through a process of elimination of holders that I know - it can only be one of 2 holders (10 and 14 in the recent top 20)."

No 14 is Forsyth Barr's nominees account, which in all probability represents more than one entity. "Forbar" are my full service broker here in NZ, and I have lots of shares in lots of companies held in their nominees account.
So could be one holder but more likely to be multiples.
