That explains it
I was puzzled by the fact the Commerce Commission set a $28.04 wholesale price for unconstrained UBS, when late last year it set the price at $27.87.
You see the wholesale price is calculated off the average Xtra retail price, and in early 2006 Telecom announced huge drops in Xtra pricing, so hence one would expect a drop in the wholesale price.
But as the Herald reports, while the monthly price dropped, there were reductions in non price terms such as data limits, and hence the overall value of the plan didn’t decrease by much, if at all!
