Some areas in East Auckland are pretty hilly... I got national roaming in the inner steeper sides of Mellons Bay:

Otherwise, I have got to say, 2degrees have done a wonderful job of providing good 2G coverage around our area. The area around Macleans College used to have very marginal Vodafone 2G coverage (good 2100 3G coverage though)... now there's full 2G coverage thanks to 2degrees installing a tower right outside the school (not that I use a phone at school :D)
