Is .nz safe? The state of .nz domain security — New Zealand
.nz is safer than the internet average. Across 579,843 graded .nz domains, 63.8% score an F — cleaner than the 78.3% global average — better company than most of the web. 3.1% earn a B or better. Most .nz domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-08-16.
In the .nz zone — covering New Zealand — 59.1% of 455,868 graded domains earn an F, well below the 73.8% internet-wide average. Only 0.3% reach an A or A+ — the highest protection tier in the census.
Note: .nz is used as a proxy for New Zealand based on the domain's TLD, not where the company is registered.
How do .nz domains score?
Aggregate grade distribution across all graded .nz domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 292 | 0.1% |
| A | 1,552 | 0.3% |
| B | 16,068 | 2.8% |
| C | 70,693 | 12.2% |
| D | 121,136 | 20.9% |
| F | 370,102 | 63.8% |
Does .nz make a domain secure?
No — and that's the most important thing to know. A domain's grade is decided by how it is configured (SPF, DMARC, HTTPS, DNS), not by its ending. Choosing .nz doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .nz domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .nz safe?
On average, .nz is safer than the internet average: 63.8% of its 579,843 graded domains score an F as of 2026-08-16, against a 78.3% global average. Most domains on every ending are exposed — the ending shifts the odds, not your own domain's grade.
How secure are .nz domains?
36.2% of .nz domains score above an F and 3.1% earn a B or better. The rest fail the basic externally observable protections, most importantly enforced SPF and DMARC, so they can be impersonated in email.
Does choosing .nz make my domain secure?
No. A domain's grade comes from how it is configured — SPF, DMARC, HTTPS, DNS — not from its ending. A well-configured domain earns an A on any ending; an unconfigured one sits at F on .nz too.
What does "grade F" mean for a .nz domain?
It fails the basic protections we can observe from outside — above all, it has no enforced SPF and DMARC, so its email can be forged and its customers targeted with convincing fakes.
