Doing a new build in a fibre area. I have a couple of questions

The land is totally clear. As there is no existing copper line installed on the site, who pays for the fibre to be laid within the property,. With existing houses it is currently free. However according to this page ,it is the land owner who is responsible for paying for everything, although I don't know if that applies in areas where the install is supposed to be free https://www.chorus.co.nz/help-and-support/wiring-broadband/who-will-install-wiring-fibre-broadband-if-im-building-new-house 

Also is it possible to not have an external pipe and ETP running up the side of external cladding?  Normally services go into a building through the slab when building new, and not piped on teh outside. Instead can a conduit be installed in the slab, and an ETP box be installed in the wardrobe, where networking gear will be located. Or is an ETP box required at all in that case, and can it just be connected straight to the ONT? Can the contractor just lay a conduit down through the slab where the exterior wall will go, with the required diameter and curve radius, to the outside. Which will then allow the chorus installers to pull the wire up through. Potentially it would make the install a lot easier for them, and reduces the risk of weather tightness issues with cladding. If this is possible, is there any info on the exact specs this needs to meet? I can't see much on the chorus website about this.

TIA
