mckenndk: If you wanted to run your own UFB conduit from the street to your house what would people recommend?

At least if you do it you know it will be done to at least your standard.

You need to follow this guide (assuming you live in a Chorus UFB area):

I installed my own conduit to the Chorus standards in that PDF, in late 2014:

It's about 11 metres from our front fence to the front of our house.

That's good to know, where would your source the supplies from?
Won't be looking at doing it until nearer the end of the year I am currently working in Canada but returning home at the end of the year and UFB is high on my list of things I want when I get home.
The place I am right now is the first I have lived in that has VDSL (54 down and 10 up) and I will only want better when I return home.

I obtained enough 20 mm green telecommunications conduit from second hand building supplies companies to span the 11 metres that I needed. You can probably purchase it from electrical suppliers also.

Rather than start a new thread, I thought I would resurrect this one.

Earlier this week, I was excavating a patch of earth for a rental property owner. He wants to extend the driveway concrete pad so that two cars can park on it.

This flat has had UFB installed using the official Chorus green conduit. I dug (with a shovel don't worry) 100 mm down (which is the required minimum depth for driveway concrete) and hit the green conduit on the corner of where the pad is to go. Seems the whole conduit was laid across the front lawn at only this shallow depth.

Is this acceptable practice?

It's not a new subdivision, it's an older flat with a grass front lawn. Because the conduit was laid at such a shallow depth, the new section of concrete will be poured directly on top of the conduit; actually touching it.

on further looking the link above only seems to be applicable if your are installing a duct.

looking at their step by step here: https://www.chorus.co.nz/installing-fibre/from-the-street-to-your-property/getting-fibre-to-your-property-revised#
it says about 200mm

but still doesnt meet that

It wont hurt it, If the concrete surrounds it and you are worried about it cracking due to differing expansion rates just wrap it in a couple of layers of insulation tape. Do a sort of rubbish wrinkled job. (pretend you are a Sky installer)

Ok. I do remember saying at the time "Christ, if I had been excavating this lawn with a Bobcat, I'd have gone straight through that conduit without even realising it was there."
