It's one of the most commonly searched questions about workplace electrical safety in New Zealand, and the answer is more nuanced than a simple yes or no.
Test and tag is not explicitly named as a mandatory requirement in New Zealand legislation. However, failing to maintain your appliances to the intervals required by AS/NZS 3760:2022 can put you in direct breach of your obligations under the Health and Safety at Work Act 2015 (HSWA). For any New Zealand business that uses portable electrical equipment, which is effectively every business, this distinction matters.
The Legal Framework: Health and Safety at Work Act 2015
New Zealand's primary workplace health and safety legislation is the Health and Safety at Work Act 2015. The Act places a duty on PCBUs (persons conducting a business or undertaking) to ensure, so far as is reasonably practicable, that the work environment is without risks to health and safety, that plant and structures are designed and maintained safely, and that workers and others are not exposed to health and safety risks.
PCBU is a broad term by design. It covers companies, sole traders, partnerships, and contractors, essentially any entity running a business in New Zealand, regardless of size or structure. If you employ people, engage contractors, or run any kind of commercial operation, you are almost certainly a PCBU.
Electrical appliances are considered "plant" under the HSWA. The duty to maintain plant safely is ongoing, and it applies whether or not a specific standard is named in the legislation.
Officers carry a personal duty too
Directors, board members, and senior managers with significant influence over how the business runs are classed as officers under the Act, and their duty is personal. It cannot be handed off to a health and safety coordinator. An officer is expected to stay informed about health and safety risks, make sure the business has adequate resources to manage them, and confirm that compliance processes are actually being used, not just signed off on paper. A director can be personally prosecuted and fined even when the company is prosecuted for the same breach.
Workers have duties as well
While at work, every employee must take reasonable care of their own health and safety and avoid actions that could harm others, and must comply with reasonable instructions and cooperate with health and safety policies. Duty under the Act runs in every direction, not only downward from management.
What "reasonably practicable" means in practice
WorkSafe NZ uses this standard to assess whether a business took adequate steps to prevent harm, and it comes down to weighing five things: how likely the hazard is to occur, how much harm it could cause, what the business knew or ought to have known about the risk, what controls were available, and what those controls would cost.
Take a frayed extension lead in a busy retail store as an example. The likelihood of contact is high, the potential harm from electrocution is severe, a qualified technician can test and tag the lead affordably, and that kind of testing is widely available across New Zealand. Every part of the test points toward action.
Cost is often misunderstood here. A business can't skip a safety control just by pointing to the cost, cost only enters the picture after the risk and the available controls have already been weighed, and a control is only excused if its cost is genuinely out of proportion to the risk. For something as low cost as scheduled portable appliance testing, that argument rarely holds up.
If an electrical incident occurs and a business cannot demonstrate that it maintained appliances in accordance with the relevant safety standard, it is very difficult to argue that it acted reasonably.
Where AS/NZS 3760:2022 Comes In
AS/NZS 3760:2022 is the joint Australian and New Zealand standard for in-service safety inspection and testing of electrical equipment. The NZ version is published via standards.govt.nz. It specifies which appliances must be tested, how testing must be conducted, the intervals at which testing must occur by environment type, and what documentation must be produced.
While HSWA does not name AS/NZS 3760:2022 directly, this standard is the recognised benchmark for demonstrating compliance with electrical safety obligations. WorkSafe NZ references it during investigations, courts have used standards compliance as a measure of due diligence, and insurance providers use it as a condition of coverage.
In effect, following AS/NZS 3760:2022 is how you prove you met your legal duty. Not following it is how you demonstrate that you didn't.
What Are the Required Testing Intervals?
Under AS/NZS 3760:2022, testing intervals are set by environment type:
| Interval | Environment |
|---|---|
| 3 Months | Construction, building and demolition |
| 6 Months | Factories, production and warehouse |
| 12 Months | Schools, offices, office kitchens (equipment prone to flexing) |
| 5 Years | Server rooms (equipment not prone to flexing or abuse) |

Sectors Where Compliance Is Most Scrutinised
While every New Zealand business has electrical safety obligations, certain sectors face closer attention from WorkSafe NZ. Construction sites have the most frequent testing requirement at three monthly intervals because the environment creates the highest risk, and WorkSafe NZ actively monitors construction site safety as part of its enforcement activities.
Hospitality and food service is another area of focus. Commercial kitchens involve high use appliances in environments with moisture, heat, and physical wear, and equipment failure in this setting creates both safety and liability risk. Manufacturing and factory environments fall under the six month interval, and the combination of high equipment use and potentially vulnerable workers makes compliance a priority. Schools and educational institutions operate under the 12 month interval, and the duty of care to students amplifies the legal and reputational consequences of electrical incidents.
What Happens If You Don't Comply?
If a WorkSafe NZ inspector visits and you cannot demonstrate current test and tag records, you may receive an improvement notice requiring you to remedy the situation within a set timeframe, a prohibition notice stopping specific work until compliance is achieved, a non-disturbance notice locking down a site or piece of equipment to preserve evidence for investigation, or in more serious cases, prosecution under the HSWA for failure to meet your duty of care.
If a worker or visitor is injured or killed by faulty electrical equipment, WorkSafe NZ will investigate, and the first thing they will examine is your test and tag records. Penalties scale with severity. A Category 1 offence, reckless conduct that exposes someone to risk of death or serious injury, can bring a fine of up to $3 million for an organisation, and up to $600,000 or five years' imprisonment for an individual PCBU or officer. A Category 2 offence, failing to comply with a duty in a way that exposes someone to serious risk, carries fines of up to $1.5 million for an organisation and $300,000 for an individual. Courts can also impose adverse publicity orders, remediation requirements, and training programmes alongside these penalties.
If records are absent, out of date, or don't exist, this significantly increases your exposure to prosecution and fines, civil liability claims, and insurance complications or claim denials. Many commercial insurance policies also include conditions around maintaining equipment in accordance with relevant standards, so a gap in test and tag compliance can give insurers grounds to reduce or refuse a claim following an electrical incident.
Does Test and Tag Apply to Every Business?
Any New Zealand business that uses portable electrical appliances in a commercial context has electrical safety obligations. There is no minimum size threshold, and no sector exemption. This includes small businesses and sole traders with employees, retailers and hospitality venues, construction contractors, healthcare providers, educational institutions, and government and local council workplaces.
The only meaningful variable is the applicable testing interval, which depends on the work environment rather than the size of the business.
What About Home Offices?
Electrical safety obligations under HSWA apply to the work environment. If workers are employed and working from home, the employer still has obligations regarding equipment they provide to those workers, including testing portable appliances where this is reasonably practicable. This is an area where many New Zealand businesses have compliance gaps, particularly following the widespread shift to hybrid and remote work arrangements.
Keeping Compliance Records
AS/NZS 3760:2022 requires that testing be documented. After each inspection and testing session, your technician should provide a compliance report listing each appliance tested, its test results, and its next due date, along with individual tags on each appliance showing the test date and next test date. These records are your evidence of compliance. They should be kept on file and available for inspection.
The Local Guys Test and Tag provides full compliance reports and certificates after every job, along with automated reminders when your next testing period is approaching.

Frequently Asked Questions
Is test and tag a legal requirement in New Zealand? Test and tag is not named as a specific requirement in New Zealand legislation. However, the Health and Safety at Work Act 2015 requires businesses to maintain plant, including electrical appliances, in a safe condition. AS/NZS 3760:2022 is the recognised standard for meeting this obligation, and failure to follow it creates significant legal exposure if an incident occurs.
What law covers electrical appliance safety in NZ workplaces? The primary legislation is the Health and Safety at Work Act 2015 (HSWA). The relevant standard is AS/NZS 3760:2022, available through standards.govt.nz. WorkSafe NZ is the regulator responsible for enforcing workplace health and safety in New Zealand.
What is AS/NZS 3760:2022? AS/NZS 3760:2022 is the joint Australian and New Zealand standard for the in-service safety inspection and testing of electrical equipment. It specifies testing intervals by work environment, testing procedures, and documentation requirements.
Can I be fined for not doing test and tag in New Zealand? Non-compliance with test and tag is not a named offence on its own. However, if a WorkSafe NZ investigation finds that you failed to maintain electrical equipment safely, you can face prosecution under the HSWA, with penalties depending on the severity of the breach, up to $3 million for organisations and $600,000 or five years' imprisonment for individuals in the most serious cases.
Who is responsible for test and tag compliance in a NZ workplace? The PCBU, typically the employer or business owner, holds the primary duty of care. Officers such as directors and senior managers carry a separate, personal duty that cannot be delegated. In larger organisations, day to day responsibility may sit with health and safety managers, but ultimate legal responsibility remains with the PCBU and its officers.
Does test and tag apply to rented or leased equipment? Yes. AS/NZS 3760:2022 covers equipment that is used in a work environment, regardless of whether it is owned or leased. If you bring equipment onto your site, whether your own or hired, it is your responsibility to ensure it is compliant.
