goback is referring to NZ to Europe fares which are quite flexible - they allow routing via Asia or North America or both (different each way). Some of these fares do allow routing via South Africa too. Thus not a RTW fare but can be made into a (simple) RTW itinerary if desired.
They tend to be much cheaper than RTW products, but also with much less routing & stopover options.
