I saw work being done the other day on the Lower Hutt cellsite but hadn't been past again.
Network is using id nz05
Apologies for the poor photo taken on max zoom on my mobile, I didn't have my camera on me to take a better photo. New 2100MHz 3G panels are on the left and existing CDMA on the right. This cell is also one that has the round CDMA panels that can automatically tilt themselves to optimise coverage and traffic depending on network load. I'll grab a better quality photo later.
