Coverage Options

Note: Coverage maps are updated on a monthly basis around mid-month. They may not reflect the coverage we have available today due to the timing of updates and the nature of coverage being predicted. RCG customers select "4G" in the options above to check your coverage. If you’re in a rural area and a nearby site has recently been activated you will see reception bars and the words 'Spark NZ' displayed at the top of your mobile whilst you are located in the area you’re expecting coverage and using an eligible device.

The Spark 4G network also powers Skinny. Learn more about Skinny NZ

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

Our network reaches 97.5% 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 97.5% 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.

Grab a SIM card

Not good news, sorry. Your phone won't run on our network.

But don't fret! We've got a great selection of phones for all tastes and budgets.

Check out the range

Please enter a valid IMEI number. The IMEI number should be 14 digits long. You can find it by dialing *#06# on most phones. If that doesn't work, open up your phone, pop out the battery and look on the label beneath it, in the battery compartment, or look on the label on the box your phone came in. You can also look in your phone settings.

On most phones, you can get your IMEI number just by dialing *#06# or checking your phone settings.

No luck? You might also find the number on a label in your mobile's battery compartment, or on the box it came in.

What else you should know

You'll need a Spark SIM card to connect to the network.

Our 5G network uses N78.

Our Initial 5G deployment is ‘NSA’ (non-stand-alone). What this means is that a device first needs to connect to 4G before it can connect to 5G. This means that at minimum, a device must support both B1 | LTE 2100MHz and N78 | 5G.

Our 4G network uses multiple bands. For the best experience, your device should support all the LTE bands listed below. Note that VoLTE support is also required for calling on 4G – for more info, check

  • 4G Essential: B1 | LTE 2100MHz + B28 | LTE 700MHz + B3 | LTE 1800MHz
  • 4G Recommended: B40 | LTE 2300MHz + B7 | LTE 2600MHz

Our 3G network uses B5 | 3G 850MHz. If your device isn't compatible with B5 | 3G 850MHz, it won't work on our 3G network. You might be able to use your device on 4G. Check our 4G bands above, and for more info about calling over 4G, check out 

Please check your phone or device specifications to ensure it's compatible.

The information in our IMEI checker is indicative only, and doesn't guarantee that your device will connect to our network. Also, please be aware that some services may be different or unavailable with a device that wasn't sourced from Spark.
