What about Tekweni Ecotours?

Note that Tekweni Ecotour’s "Zululand Grassroots Experience Safari" does enter the chloroquine-resistant areas of Zululand, however our accommodation is situated in a presently malaria free pocket and there is not risk of contracting malaria while visiting the main game viewing park during daylight hours. Tekweni Ecotours has been visiting these places once a week every week of the year for the last 6 years, and as of yet none of our guides have contracted malaria and we are not aware of any of our guests having contracted malaria. As a matter of interest none of our staff have ever used prophylactics while on tour.

Note: Our safari that visits the Drakensberg Mountain Range, "Rejuvenate Your Soul" does not enter any malaria areas at all.
