Our networks team is working constantly to improve our mobile network's coverage and capacity. Here are the upgrades completed for March 2017 so far.
You can find our planned upgrades for coming months here.
The coverage maps are updated monthly, so new changes might not be listed yet. You can check the coverage maps at http://www.vodafone.co.nz/network/coverage/ and we'll update them with the above sites soon.
I'll update the list above as more sites are upgraded or added during this month.
