What 3G, 4G, 4.5G and 5G means for you

Our network reaches 98% of New Zealanders.

  • 5G is faster and carries more data than previous generations (4G, 3G, 2G and so on). 5G has the potential to reach download speeds of up to 100 times faster than 4G. It has the potential to bring super-fast downloads, minimal latency, massive connectivity and outstanding reliability.
  • 4.5G: Up to 3–5 times faster than 4G with some compatible high-end devices
  • 4G: Super fast speeds for data browsing. To maximise coverage, we recommend a phone that supports 4G 700MHz. 4G HD Calling is also available in these areas for eligible customers. Check if you're eligible for 4G HD Calling
  • 3G: World class 3G speeds covering 98% of New Zealanders

The map indicates where we estimate our network coverage is available. Your experience may vary from the coverage shown depending on mobile capability, how it's used, and the local environment.

You can also look in your phone settings.
