Some of Chile’s most renowned Cabernets come from the Maipo Alta region, which is a little cooler; here Cabernet Sauvignon produces elegant wines characterized by intense black currant flavors with a hint of eucalyptus. In the warmer regions, it gives richer and fast developing wines with a softer tannic structure, sweet fruit and less acidity. 
Argentina has been growing Cabernet Sauvignon in the Mendoza valley close to the Andes for over 100 years, and some of the finest examples again come from the cooler sites. Wine producer and journalist Gabriel Dvoskin pointed out that Argentina is the only region in the world to grow a "continental" style of Cabernet Sauvignon and told me that there are currently a lot of experiments going on to define the specific characteristics associated with this style. This is may be why often Argentinian Cabernet Sauvignon is typically blended with Malbec. In general, Argentinian Cabs are quite exuberant and high in alcohol, and young drinking wines show typically a lot of bold stewed fruit. 
South African Cabernets often show a lot of ripe sweet fruit as well as some herbaceous and minty notes, whilst in New Zealand herbaceous characters and cassis flavors tend to be more dominant. Although some single varietal South African Cabernet Sauvignons are excellent (especially from the Stellenbosch area), the Bordeaux blends remain popular. In New Zealand, Cabernet Sauvignon is generally grown in the warmer region of Hawkes Bay, but even here it struggles to completely ripen. That is why it often forms the backbone of the excellent Hawkes Bay Bordeaux Blends.
