The two younger Cachopa boys certainly look very Afrikaans, so that is good enough for me . Munro also has bit of accent, and was also born there. So i wouldn't exactly say they are much more kiwi than they are South African.Munro and the Cachopa boys are much more kiwi than saffer. I think the Cachopa's in particular spent most of their lives here. No idea about Munro.
With the amount of South Africans flooding into Auckland though their team will probably have a very afrikaans look to it when the second gen kids grow up.

But you are right about the next generation coming through, especially in Auckland/North Shore. However I see them being more English than Afrikaans. I know two of Auckland's better young batsmen are from South Africa in Bradley Schmulian and Rob O' Donnell.
