How we help
Simple, confident recording for NZS 3000 testing — you keep control, we keep it clear.
Filling COC’s and ESC’s shouldn’t be hard
They should be easy, relevant, and complement your work in a supportive way. The coc.nz portal is designed with that in mind — it’s about hands-on testing first, and the certificate is simply the proof that the testing was done and the results were acceptable.
Testing drives the certificate
Your certificate can’t exist without the testing having happened — the testing drives the certificate, not the other way around. That’s how it should be: the paperwork naturally follows the work — and with coc.nz, you don’t even need paperwork, because the real work is in your hands-on testing.
We don’t judge your results
coc.nz doesn’t decide whether a test passes or fails. It simply records what you’ve done and gently prompts you to consider whether each test is relevant to the work and the certificate being completed. The goal isn’t to audit you — it’s to help you think through the process, record your results clearly, and generate a professional certificate that reflects the job as it was actually done.
Built by a tradie, for tradies
coc.nz was built by a tradesperson with experience working in the industry. It walks you through the common tests that might apply to your work and gives you supportive prompts to think about each one. You can skip any test that doesn’t apply — no problem. Only what you record shows up in the final certificate.
It’s built to protect your work

Fast and easy
Because the system automatically saves and reopens draft certificates, you can enter job and address details whenever it suits — out on site, or later when you’re back at the office. That means in the field, you only need to focus on entering your test results.
And because those results are entered as you perform the tests, the certificate just flows naturally.
The job’s not complete until it is fully complete
The built-in signing, auto-emailing, and instant download make the certificate-generating process fast, seamless, and most importantly — done.
