How does the licence fit with primary licences or subscriptions?

Copying can be done under either the primary licence or the CLNZ licence. CLNZ licences are intended to be complementary to primary licences. Use whichever licence best suits your needs, even if the CLNZ licence is more generous than the primary licence, but the CLNZ licence cannot be used to justify overriding or circumventing any DRM embedded in a digital product.
