A quick look at rollout maps indicates that "towns that have UFB" actually don't - in their entirety. So, its inaccurate.
Looking at Palmerston North for example, the entire left side has no plan or timetable for UFB.
Other citys where a quick glance indicate 1/2 a city does not intend to get coverage:
- Christchurch (Little above 0%)
Hence these Gigatown promotions marginalize 40-50% of their population. The press releases are cunning though : PR sent to local bodies who scramble to publish in a look-how-great-our-town-is flurry.
