I still stand by my first reply on this though we will not see real competition until there is a second line into the country. Basically as Telecom have the network all to themselves how can you create real competition (unless you count Telstra with their limited reach of cable as competition).
Real competition needs to become a priority as onsellers can't generate much competition as whomever they buy off can always undercut them. Why do you think most companies have similar pricing.
While a second major transit link to Australia and the States would have some affect on driving down costs but I dont think it would make as much difference as you think.
There is quite a bit of competition out there any many international IP transit provders to purchase bandwidth through. Southerncross have slashed their prices over the last few years quite dramatically which has caused a roll on effect on the pricing from GGI, Telstraclear, PACNET, Verizon, Vocus and AT&T.
The bandwidth cost is only one portion in the total cost of providing DSL to users though, the Telecom leased DSL port prices make up the biggest part of your DSL bill by far, and Telecom/Xtra also have to pay for the port costs from Telecom Wholesle just like any other ISP. Then there is also the cost of marketing, staff, support and network/systems costs so it all adds up.
Totally agree that if there was another national physical phone line provider out there that the DSL port costs would be far far lower.
I believe most ISPs have similar pricing as they offer just about the same service. There are not many ISPs out there which can honestly say that they have a service which is clearly different to the competition.
When was the last time people made a huge fuss about the cost of lamb in NZ or the price of cheese or even electricity. It seems that some people base their whole perseption of a country on their Broadband offerings alone, which to be honest, is not that bad at all if you shop around.

. My rambelings may seem odd or biased towards ISPs but working for one gives you a very different picture of the industry.
