Bigpipe is a naked service, just a adsl/vdsl/ufb connection that's uncapped. No extra addon's like provided email etc, no phone user support, just email only.
They also have no contracts so if you want to leave after the 2 months there's nothing stopping you.
I would recommend looking into the deal if you want ufb in auckland(only supported city right now) as they are well priced, UFB Starter 100/20 for $79 a month.
I used a similar deal with them last month, was $20 or $29 for $100 credit and 1 month free. Which is basically $19 for 2.5 months service. THey even installed a VDSL splitter which was nice. I'd recommend this deal to anyone, you can't get much better.
