We prove that Z-stable, simple, separable, nuclear, non-unital C * -algebras have nuclear dimension at most 1. This completes the equivalence between finite nuclear dimension and Zstability for simple, separable, nuclear, non-elementary C * -algebras.1 i.e. (a) A is a simple, separable, nuclear and Z-stable C * -algebra if and only if A ⊗ K is likewise, and (b) dim nuc A ≤ 1 if and only if dim nuc (A ⊗ K) ≤ 1; see Proposition 2.3 for details and references.
