Its been ages since I last posted on any thread so here goes!
I am only going to comment the medical side of things let me tell you my experience....
Before we left SA 18 months ago I suffered a miscarriage. Thank goodness we had medical aid because the subsequent D&C would have set us back R10 000 .... OUCH
I am now 7 months pregnant with our "little kiwi" and all my medical care has been free. I have had 2 sets of blood tests, 2 scans, monthly mid wife visits, 2 Dr visits and they are all FREE...
How much would this have cost back in SA?? Even with a Medical Aid.
My 1st job in NZ was working for a DHB that managed funding for disability services... anyone who was eligible was entitled to equipment FOR FREE - hospital beds, wheels chairs, hearing aid subsidies etc - to check if you are eligible go to MOH's website and look it up.
Now tell me what support does the SA governmunt offer it's disabled people?
I am now working for another DHB where kids get FREE vaccinations (this is applicable across NZ)...
If you are on a 2 year work permit or longer you are entitled to the same treatment as Kiwi's for medical care... if you are been charged $75 for a Dr's visit then your Dr is ripping you off. The most we have paid is $30.
Working in the health industry is so different - the nurses don't even wear gloves!
Yes NZ is not all petals and roses, yes it is hard to make new friends, it is expensive to keep your house warm in winter, the weather can been very depressing, that finding a job has become harder and harder - but the job situation is NOT unique to NZ - just ask anyone living in the UK at the moment!
Would I trade the negatives to go back to SA?? Not on your life, and now more than ever not on my child's life. The lucky little bugger even gets his NZ passport when he is born! We still have 4 years to wait.... that reminds me we have had our PR now for a year !!!

You have to be realistic and understand that immigration is not for sissies. If you have any relationship problems, any health problems any doubts at all, trust me immigration will make you face those and deal with them!
Our biggest regret? Not coming out sooner!
