Firstly I must apologis(z)e for that shocking representative from New Zealand! We aren't all like that.
A few of us have been looking at starting a sorority in Wellington (the Capital) and have found this forum so helpful! From this thread alone was the great idea to contact the local American Women's network. Thanks for all your help so far!
Being aware of the distance and the logistics involved, we are pretty sure that we won't be able to become members of an American sorority, but it isn't going to stop us becoming "Greek"!
