In a few days fibre will be installed at my house.

My main concern is Chorus tech's doing a half job of burying the cable and a tree's roots causing more pain.

So, How do you think the fibre should run between the street box and the corner of my house? I'm probably going to dig a trench myself or at least help the techs.

Red curve (A) is concrete garden edging which is about 300mm deep, easy to run conduit underneath without lifting it out.

How does the copper get into your house. Do you know where the ETP will go on the house?

Personally i would run my own conduit but you may have left that a little late

Chorus have already been around to scope it out.

ETP is going on the brick column (red circle) and there's already a string line in the wall cavity to pull it into the roof space. Internal paths is all sorted.

The street copper connection is at the other side of the house..... just a slight oversight by Chorus when adding fibre to the street.

I've got a little while to get out there with a spade and start digging.

It's likely not an oversight. When designing the fibre network, the Chorus boffins started with a blank sheet of paper and no credence (or at least not much) was given to the location of existing copper infrastructure.

The main reason for this is because the copper network in NZ was built and then added to/expanded over the course of one hundred years (give or take). As suburbs got bigger, subdivisions were created, and whole towns expanded ever outwards into the countryside. And then after that, people started carving their quarter acre sections up for infill housing. To cater for all this growth, new network was continually "tacked on" to existing network in a fashion that was not exactly logical, but it served its purpose in making service available to newer homes as new streets were built (or extended). But this ad hoc method of continual expansion means there is a mass of duplication and inefficiency built into the copper network across the country over more than a century.

Chorus could have chosen to mirror the copper network exactly as it is, but that would have been incredibly inefficient - and therefore costly. So the answer was to design the fibre network as a completely new entity with a single goal - connect the largest number of dwellings & businesses using the least amount of cable, whilst allowing for future growth.

The underground and aerial pathways for fibre are far more efficient than their copper counterparts, and for that reason, nobody's fibre drop-off point is guaranteed to be on the same side of their house as their old copper lead-in.
