I find this curious.
When you bundled One NZ broadband and mobile together. You got $10 discount. This discount has now been scrapped. I wonder if existing customers will have it removed?
It's starting to look like One NZ is showing it's Vodafone colours again! This is a easy $10 extra without technically increasing the base price.
