FYI the link from the 2degrees webpage for your 2degrees appears to be broken at the moment.

If you want your 2degrees mobile, go to:
https://www.2degreesmobile.co.nz/your-2degrees

if you want your 2degrees broadband, go to:
https://secure.2degreesbroadband.co.nz/


Hopefully they will notice their mistake soon.
