Is it best to pre book or is there a proper taxi rank at the airport.
I guess you are posting this on the uMhlanga Rocks forum because that is where your accommodation is.
Check with your accommodation first to see if they offer an airport transfer service. If not, try avis.co.za/LatestNews/…
If you don't fancy that then there is a general taxi rank outside the arrivals.
