There is mostly CV structure for onsets. Books like Bold (1977) give homorganic nasals before consonants (e.g. ndoda 'young man''); but these probably only occur in the speech of Zulu speakers of the pidgin. Other speakers don't have a preceding homorganic nasal in such words.
One exception to CV onsets is with s + {p,t,k}, and occasional words with skw - e.g. skwam 'pocket' and str - e.g. streyit 'straight'. In other words, a tendency to reduce Zulu onsets to a simple CV structure is counterbalanced by words from English.
