My experience
I have a fair bit of experience with the Chorus system, as rolled out in New Zealand, and to be fair it depends entirely on the subcontractor sent to your site.
I spent 18 months arguing with various idiots sent by Chorus when I was trying to get a new (backup) fibre link into an industrial site in an industrial suburb in Auckland. Eventually a subbie turned up who listened to what I told him, made some notes and did as he was told. I had my new connection a week later.
My home is down a shared driveway, so all the neighbours had to be involved in the fibre install which might have been a problem except my neighbours include a construction project manager and an infrastructure project manager so when the subbie turned up, they told him exactly what they wanted and how to do it and it all went very well.
I expect the Aussie nbn debacle has something to do with the constant political interference. Over here the taxpayers handed over a bunch of money and told the network providers to get on with it, and it seems to have been not too bad.
Depending on the quality of the sub contractor, obviously.
