When moving house is there a chance you may be put on a waiting list for broadband, even if that house is not rural and in the middle of town/main center with ADSL2/VDSL available? Does chorus install enough ports for every house where theres high demand and high concentration? Im assuming all these problems are solved with fiber?
There is a chance that you could be a waiter even in a main centre. A friend moved into Parnell ( Central Auckland ) a year or two ago and has just recently been told that he can be connected to dsl.
Fibre should mean that is a thing of the past as both phone and internet are supplied over the same equipment rather than having a copper line for the POTS and then jumpering to the dsl equipment. A lot of exchanges can have limited space for extra racks/power although cabinetisation can alleviate that.
