Spark coverage map
Check the Spark coverage map anywhere in New Zealand. Sogudo shows estimated Spark 4G and 5G network coverage at street level - computed from public antenna data, so you can see what Spark actually delivers at your address before you commit.
How good is Spark coverage?
Spark has one of the largest networks in New Zealand, with solid 4G reach beyond the cities and growing 5G in larger towns. But Spark coverage changes from street to street - use the map above to check the expected signal exactly where you need it.
Spark 5G coverage
Switch the map to 5G to see Spark 5G coverage areas. Where 5G is unavailable, the phone falls back to Spark 4G. The Spark 5G map is modeled from antenna data and updated monthly.
Check Spark coverage at your address
Enter an address or postcode and Sogudo shows the expected Spark coverage and network type at that exact point. Move the marker to compare neighbouring streets - useful for a new flat, office or trip.
