Just to clarify VisionStream is just for the external wiring, I am sure internal wiring (ONT etc etc) are done by a separate team.
Nope generaly (for Chorus) your job will be handled by one of the three main service contractors - DownerNZ, Transfield or VisonStream / They each have teams withing an area that do differnt aspects of the job - If our Externals are being done by VisionStream then a differnt team from VS will do the internals
