Could someone please help me?

According to page 17 of the customer brief here http://www.telecom.co.nz/binarys/adsl2_customer_brief_may_2007.pdf the Dlink DSL-502T modem supports only ADSL1 connections on an Interleaved profile. I have a friend who got a Dlink from XTRA, how can I tell if it is one of those?, and What profile do telecom support?

According to the information here http://www.telecom.co.nz/binarys/adsl2+%20roll-out%20update-003.pdf the next area to get ADSL2+ is St Albans, which is where my friend lives.

Could this be the reason that ADSL2+ rollout is slow? because XTRA modems do not support it?

Not a help on the technical question, but I don't think the modem support for ADSL2+ is the reason of how fast or slow the deployment is.

There's no correlation at all - if someone wants ADSL2+ then just need to get a new modem when the service is avaialble. Or do you think people would consider first purchasing new devices to only then Telecom consider start deploying? Nope, I don't think it's related with something as simple as the modem in use.

I thought it might be related. I mean if I had 50,000 odd customers who had hardware that was unable to connect at the new network speed, and my competitors customers had no problems, then I may be reluctant to roll out the network upgrade to help my competitor.
Why buy a new modem, when you can join a competitor ISP and get a free ADSL2+ certified modem?

I have a 502T and it supports ADSL2+. However, it is speed limited for interleaved connections. It is a hardware issue, the 504T has the same problem until you get to generation II and hardware version 2. The 502T generation II is not listed, and I suspect the latest version will also do 20Mbps (but I'm not going to waste $100 to find out, rather getting a decent modem).

So Telecom is not selling slow modems (any more). The other advantage of ADSL2+ is that it will dynamically lower the transmitting power when not needed, to reduce crosstalk. So even if using an old 502T which connects at a limited ADSL2+ speed, you still get a network quality inprovement.
