We are in Nelson. We got our ONT installed in the middle of the upper level of two story house, exactly where we wanted for no extra cost (added about 10m to the fibre run).
We had initially been told a 'back to back' install was the only free option, regardless of suitability.
They (Chorus subcontractor Transfield) had mucked us around a lot, so I think they were keen to look after us .... or perhaps they were just happy to be rid of me
