Not to my surprise we did not get any official comment neither on the blog itself or here where there's a TelstraClear account which they could use to let people know things.
Today I found out on Stuff that the upgrade is not coming until mid 2008 for Wellington:
TelstraClear expects to offer 25 megabit per second broadband connections to customers of its Wellington cable network by mid-year.
The lightning-fast 25Mbps plans should be available in Christchurch next month, says spokesman Chris Mirams.
TelstraClear had originally promised the faster broadband plans last year. Mr Mirams says the upgrade was held up by the availability of equipment that has only recently become available, and which arrived in New Zealand shortly after Christmas.
