In the domain.co.za zone db file, do this:

; Delegate sub.domain.co.za
sub     IN      NS      ns1.sub.domain.co.za.
sub     IN      NS      ns2.sub.domain.co.za.

; Glue for ns1.sub.domain.co.za and ns2.sub.domain.co.za
ns1.sub IN      A       10.10.10.1
ns2.sub IN      A       10.10.10.2


The 2 NS RR's are the delegation.  Because the two name servers for the 
new zone end in the parent's domain name, you must include A RR's for them 
in the parent zone file so other name servers can get the IP addresses for 
ns1.sub and ns2.sub.  If the new name servers are in some other 
domain/zone, then, it is the responsibility of the other zone's 
administrator to maintain these A RR's.
