Goeie flipping Nugtig!!!
Immigration agents used to charge only $30,000 - $35,000 before (which is still exorbitant!). What they're now telling you is that no matter whether you succeed or not, they will still make that $30,000 off you!

And that dear friend, is the price of your container of taking your valuable and lovable stuff with you!
NO WAY!!!!
As all above have said, you CAN do this yourself. The system is really straight forward (unlike the USA). And the immigration people here in NZ are really friendly, they're not spiteful like the SA home affairs.
I think Nolan still has the checklist here of what docs you need to get in SA:
like unabridged Birth Certificates;
Marriage certificates;
references from previous employers (if you can);
proof of working for those employers, if you can;
proof of marriage/relationship (other than certificate) - i.e. bills under same name, stuff addressed to you at same address, bank account in both names,etc.
Any qualifications translated into English (if they're not already in English).
Fingerprints for police clearances.
And don't forget the PASSPORTS!
There is a company called Bunnyhop that can help with getting birth & marriage certificates faster - they do charge, but I think it's something like R500?
The rest of the actual immigration stuff is on the NZ government site:
check the skills list to see if you're on the short list.

FIRST.
You will need that whether you apply for Work Permit first, or whether you are able to apply for PR from the get go.
As you can see, most of the above is all stuff you do yourself. And personally, I would be loathe to have any more people handle all my personal documents than is necessary. Therefore, sending docs directly to the NZQA or the NZIS, and not through an agent, is far better.
