I don't know if there are or were or will be any former South Africans living in New Zealand who visit these boards, but I just thought I'd link you guys if you want to get in touch with old school friends, army buddies or even old work colleagues.
And the best news is it's now completely FREE to contact people on the site.
Find old South African school friends - SAReunited, South Africa
Have Fun!
Edit: Just as a side note. I did note that in search area you can select other countries, so maybe if one of you guys living in
NZ can check if you can see if it's possible to look for your old schools and stuff as well, then maybe you guys can use it to track down old school friends as well. Lemme know if it works.
