With fibre to the home, would this solve the problem of a full telephone exchange where if a new user wanted broadband he/she will have to wait until a port becomes available? I hope it does because I heard everyone talk about speed but no-one ever talks about making sure every household has access. I think it's a human right for every house to have power and water but I don't think it applies to broadband.

Fibre will solve that issue because fibre needs to be run to every home.

The issue in itself has already been solved by Telecom's cabinetisation project though, port shortages don't exist in areas where the network has been upgraded.

Surely putting 1 cabinet in a suburb with tens of thousands of people will not be enough to give them all broadband ports would it?

Then will be ~3600 cabinets by the time they are done, the standard double door whisper cabinets do about 300 lines each.

Also remember that all the houses within 1-2km of the exchange will still be connected to the exchange and the exchange equipment will be upgraded to VDSL.

Also of course multiple people in each house.

It will not guarantee you will be able to have broadband. There is no way that anyone will build enough capacity to GUARANTEE that everyone can have as much as they want. The chances of being told "sorry, we don't have capacity" will be much less though and you will have more optoions.

If a fibre is run to your house, you will be able to get broadband - as simple as that.

A cabinet doesn't serve thousands of customers. The number of MPF's served by the bulk of cabinets is in the vicinity of 192 - 288 lines, with 288 lines being a "standard" cabinet.

A comment like yours suggests you aren't actually aware of the configuration of the cabinets. 48 port ADSL/ADSL2+/VDSL card are used in the ISAM and the whole 288 lines (in the case of a 288 pair MPF's) are available for ADSL/ADSL2+/VDSL connections across the vast majority of cabinets. If Telecom decide to deploy POTS emulation cards these will also be available for the whole 288 lines as well. This means that every MPF that leaves the cabinet can be provisioned for ADSL/ADLS2+/VDSL. In some areas there are also 24 port G.SHDSL cards fitted as well so ADSL/ADSL2+/VDSL isn't available on every port (a couple of the cards are removed) but a DSL based service of one form or another is still available on every MPF that leaves the cabinet.

This comment in regards to sub loop unbundling is also very relevent

Under the TSO, Telecom is obligated to make the standard residential
telephone service as widely available as it was in 2001.[1] This
availability requirement requires Telecom, in most cases, to provide
sufficient capability to service all end users served off a cabinet.
Therefore, Telecom must ensure there is sufficient capacity available at
the cabinet to meet demand from connected residential customers.

Because of this requirement Telecom have had to ensure that DSL based services are available off every MPF served from a cabinet. Voice servies are also required to be available to every MPF served from a cabinet, whether they be PSTN emulation or VMUX services deployed from a cabinet, or voice services carried over the existing MPF copper feeds from the exchange to the cabinet.

I am not entirely sure on this but if GPON technology is used, doesnt that mean the the word port becomes branch or something to that effect?
Which would mean you need to have enough branches avaliable off the trunk line running past your house because the transmitter back at the cabinet only supports something like 12 branches off the trunk line?

The port is just the connection on the DSLAM card, so can also apply to a GPON card, in fact GPON can be in the same DSLAM box for some manufacturers. A shortage of ports is almost always, but not quite always, due to a forecasting issue with DSLAM cards in the DSLAM, ie not enough cards for the number of customers. In the case of an exchange, where more space is likely to be available, it may be due to insufficient DSLAM's to take any more cards - another forecasting issue.
