Test and Tag for Auckland Businesses: What the Rules Actually Require

Test and tag is not, strictly speaking, compulsory for most New Zealand workplaces — but under the Health and Safety at Work Act 2015 you must ensure electrical equipment is safe, and regular testing to the AS/NZS 3760 standard is the accepted way to demonstrate that. On construction sites, testing is effectively mandatory. Here is what that means in practice for an Auckland business.

What is test and tag?

Test and tag is the routine inspection and electrical testing of portable, plug-in equipment — kettles, power tools, extension leads, computers, heaters — followed by a dated tag showing the item passed and when it is next due. The visual inspection matters as much as the electrical test: most failures found are damaged leads and plugs, not internal faults.

Is test and tag a legal requirement in NZ?

There are two layers. The Health and Safety at Work Act 2015 requires every business to manage risks, including electrical risk — it does not name test and tag specifically, but testing to AS/NZS 3760 is the recognised industry method for showing you have done your part. For construction and demolition sites, AS/NZS 3012 applies, and tools and leads must carry current test tags or they do not come on site. If an incident happens and your equipment was untested, expect WorkSafe and your insurer to ask why.

How often does equipment need testing?

Frequency depends on the environment, because the standard cares about how hard the equipment lives:

• Construction sites: every 3 months

• Factories, workshops and places where leads get flexed or abused: every 6–12 months

• Offices and other low-risk environments: typically every 5 years for fixed IT-style equipment, more often for anything that moves around

• Hire equipment: before each hire

These are the standard's guide intervals — a competent tester will confirm the right schedule for your specific environment during the first visit.

What does test and tag cost in Auckland?

Pricing is usually per item, commonly a few dollars each with volume discounts and a minimum charge per visit. For most small Auckland businesses an annual visit costs a few hundred dollars — far less than one WorkSafe investigation or one electrical fire. Combining test and tag with other scheduled electrical maintenance in one visit keeps the cost down.

Frequently asked questions

Who can legally test and tag?

A 'competent person' under the standard — which includes qualified electricians and trained test-and-tag operators using calibrated equipment. Using an electrical contractor means faults found can often be repaired on the spot rather than just tagged out.

What happens to items that fail?

They are tagged out of service immediately. Many failures — damaged plugs, worn leads — are quick, cheap repairs; the item is then retested and returned to service the same visit.

Do RCDs need testing too?

Yes — portable and fixed RCDs have their own test requirements under the standard, including push-button checks and periodic trip-time testing. They are easy to fold into the same maintenance visit.
