How this map is built

0% of the sites have known antenna azimuths: their coverage is drawn as sectors, the others as circles.

83% of the sites have a published antenna height; the model assumes 35 m elsewhere.

Frequently asked questions about One NZ coverage

Does One NZ have good coverage in New Zealand?

Coverage changes from one street to the next, so the answer depends on where you are. Search your own address on the map above to see the One NZ signal there.

Does One NZ offer 5G in New Zealand?

Yes. One NZ runs 5G from 1,182 of its sites. Switch the map to 5G to see the covered areas.

Is the One NZ map up to date?

The map is built from antenna data dated October 2026, and the One NZ network facts were last verified on August 14, 2026. Sogudo does not resell One NZ data. Coverage accounts for each antenna's sectors, the terrain between you and the antenna, and the density of the built environment around it.

Is Sogudo affiliated with One NZ?

No. Sogudo is independent and computes coverage from public antenna data.
