kia ora hello long time no see etc etc - but this fascinates me.
I'd reverse it all -
Q: how does Wynne's NZ nationality allow him to (hypothetically) represent South Africa?
A: he could qualify to represent South Africa based on him, and his parents being born in 'that territory' - so long as his passport's still valid...
I don't reckon he needs the regulation, dispensation, exemption, whatever - as far as football's concerned, he is a legitimate NZ representative...with no intention to play for anyone else.
IF he wanted to 'do a Diego Silva' now, SOUTH AFRICA would need to apply for the dispensation. I think.
Gonna read the rest of the thread now!
[edit: forgot to quote, didn't make sense. Nothing unusual some might say...]
