I'm going through the process of getting UFB installed at my place and am wondering if anyone else has been hit by this (what appears to be) unwritten rule.

My property has aerial cabling with Power and Cable going down the left of the house terminating at the bottom left by the garage and copper terminating to the very top of the house. I'm not utilizing the copper and have no need for it in the future and none of this cabling crosses boundaries into other properties (so no consent issues).

I'm told by the installer that they're not allowed to take the easier/simpler path where the power/cable is running and instead they're only allowed to run the fibre to the very top of the house and then all the way back down to where the rest of the cabling terminates, this is obviously not an optimal run and won't look particularly nice however I'm really struggling to get anyone to do the work in a manner that is reasonable.

Is there some rule that I missed where they can't deviate at all from existing copper infrastructure? The tech who came showed me he had someone prior cancel their install due to a similar matter.

I'll eventually cave in but pretty disappointed that I appear to be exhausting options to make the cabling look decent.

I'm in Wellington if this matters - unsure if the rules are different throughout the country.
