And who are you going to get to do that?
No one is allowed to touch it except Chorus (I'm assuming it's their network), and contacting/contracting them directly is near enough to impossible.
At least part of an install is supposed to be subsidised. There will likely be no part of that install that is reusable so the cost will be for an install from scratch, AND it'll cost more to undo what's been done.
Any directional drilling or trenching company can push chorus conduit thru to their spec, and then chorus come out and move services over to the new conduit.
They have an install. It is working. If they had requirements about the aesthetics of the install it should have been discussed with chorus before the installation and the private contractor arranged for anything above spec of what chorus would install from the govt contribution towards the installation.
Sounds to me like there was no discussion about how it'd be done.
Either way, I disagree with your point of view, this kind of workmanship is unacceptable in any situation.
