If you’re asking whether test and tag is a legal requirement in NZ, the honest answer is no; not exactly.
However, that doesn’t mean test and tag is something you can afford to skip. It’s still central to keeping your workplace safe and compliant. We cover what New Zealand law actually expects and what that means for your business.
Is Test and Tag Actually a Legal Requirement?
No single law in New Zealand says every workplace has to test and tag its electrical equipment. What the law does say is broader. Under the Health and Safety at Work Act 2015, every business has a duty to keep people safe, so far as is reasonably practicable. That duty covers the electrical equipment your team plugs in daily.
The Electrical (Safety) Regulations 2010 point to AS/NZS 3760 as the recognised way to show you’ve met that duty. So, while test and tag isn’t its own standalone law, it’s the standard that WorkSafe and most insurers expect you to follow. Skip it, and you’re not breaking a specific test-and-tag rule, but you may be falling short of wider safety obligations.
Understanding Test and Tag Requirements in New Zealand
Test and tag regulations in New Zealand aren’t in a single document. They’re a mix of the Health and Safety at Work Act, the Electrical (Safety) Regulations 2010, and the AS/NZS 3760 standard that ties it all together.
In practice, that means a PCBU (the business or person in charge of the work) decides whether to test and tag, but if they do, it must be carried out by a “competent person” using proper testing equipment. WorkSafe enforces the wider safety duty, not the standard itself.
If you want a clear picture of where your business stands, a commercial electrician in Auckland can walk you through what needs covering as part of a broader electrical equipment inspection in NZ that looks beyond just portable appliances to your switchboard and fixed wiring too.
What’s the Ideal Test and Tag Frequency in NZ?
How often you need to test and tag depends entirely on where and how the equipment gets used. AS/NZS 3760 sets out indicative intervals; the more demanding your environment, the more often testing is required.
| ENVIRONMENT | SUGGESTED TEST AND TAG INTERVAL |
|---|---|
| Factories, workshops, and manufacturing sites | Every 6 months |
| Construction sites and hostile environments | Every 3 months |
| Hire equipment | Before every hire |
| Offices and other low-wear environments | Up to 5 years |
| Hotels, motels, and hostels | Every 2 years |
These intervals are a starting point, not a hard rule. A documented risk assessment can adjust them, and manufacturing instructions or your insurer may expect more frequent checks. If you’re not sure what the right test-and-tag frequency in NZ looks like for your site, that’s a conversation worth having before your next round is due.
What Happens If You Don’t Test and Tag?
Skip test and tag altogether, and you’re not automatically breaking a specific law, but if an untested appliance causes harm, WorkSafe can (and does) look at whether you took reasonably practicable steps to prevent it. No tags, no records, and no risk assessments tend to make that a hard case to argue.
It can also affect your insurance. Some policies expect proof of compliance before they’ll pay out on a claim involving faulty electrical gear. A folder of expired or missing tags is the kind of detail that draws out a routine claim.

Test and Tag FAQs
Is test and tag legally required in NZ?
Not under one specific law. All businesses have a general duty under the Health and Safety at Work Act 2015 to keep their people safe, including those using electrical equipment. Testing and tagging to AS/NZS 3760 is the recognised way to prove you’ve met that duty, which is why the question “is test and tag a legal requirement in NZ” comes up so often. It’s not compulsory by name, but it’s the accepted evidence that you’ve done your part to ensure safety on your site.
How often should test and tag be done?
It depends on your work environment. For factories and workshops, testing every 6 months is ideal; for construction sites, every 3 months is best; and for offices, 5 years between tests is acceptable. Hire equipment should be checked before every single hire, no exceptions.
If you want the full test-and-tag frequency in NZ broken down for your specific industry, it’s worth getting a proper site assessment rather than guessing.
Does test and tag have to be done by an electrician?
No. Under AS/NZS 3760, test and tag has to be carried out by a “competent person”, someone with the right training and equipment. They don’t have to be a registered electrician. That said, using a qualified electrical contractor means any fault found can often be fixed on the spot, rather than tagged out and left for someone else to sort.
