One other thing that intrigued me about the article was this comment:
"HSDPA performance in Wellington is likely to be patchy, due to the capital's hilly topography"
It doesn't say whether this comment is from Vodafone or the Victoria University expert in the sentence above but it's a bold comment - 3G coverage in Wellington is very good, if not better than Auckland which seems to still have significant issues with dropouts.
