What Is WorkSafe New Zealand?
WorkSafe New Zealand is New Zealand's primary workplace health and safety regulator.
Its responsibilities include promoting workplace safety, providing guidance, monitoring compliance and taking enforcement action where appropriate.
WorkSafe's guidance helps businesses understand their responsibilities under the Health and Safety at Work Act 2015 and other applicable legislation.
Importantly, WorkSafe is a regulator — it is not an electrical testing standard.

What Is Energy Safety?
Energy Safety is the part of WorkSafe responsible for regulatory functions relating to electricity and gas safety.
Its activities include electrical product safety, electrical installations, compliance monitoring, accident investigations and enforcement.
Energy Safety also provides guidance on electrical equipment, imported products, electrical work and compliance with the Electricity (Safety) Regulations.
For businesses, this information is particularly useful when trying to understand the difference between an electrical appliance being safe to use and a product meeting the requirements for supply or sale in New Zealand.

What Does WorkSafe Say About Electrical Test & Tag?
This is probably one of the most frequently misunderstood areas of workplace electrical safety.
WorkSafe explains that electrical Test & Tag is not universally mandatory.
What businesses must do is ensure that electrical equipment is safe and maintained in a safe condition.
Testing and tagging is one recognised way of helping demonstrate that equipment has been inspected and tested.
However, a test tag does not guarantee that an appliance will remain safe until its next inspection.
An appliance can become damaged or develop a fault after being tested.
WorkSafe also explains that the decision to test and tag depends on the equipment, workplace conditions and applicable requirements.
AS/NZS 3760:2022 provides the recognised framework commonly used for in-service electrical equipment inspection and testing.
→ Read our AS/NZS 3760:2022 guide
Official WorkSafe resource: WorkSafe – Testing and Tagging Electrical Appliances
Does Every Workplace Need Annual Electrical Testing?
No. There is no universal WorkSafe requirement for every electrical appliance in every workplace to undergo annual Test & Tag.
The appropriate inspection and testing arrangements depend on the risks associated with the equipment and its operating environment.
For example, a computer operating in a dry office presents different risks from a power tool regularly used outdoors on a construction site.
Some workplaces may manage certain low-risk equipment through appropriate visual inspections and other safety measures.
Higher-risk environments may require more frequent inspection and testing, and specific regulatory requirements can also apply.
The important consideration is whether the business has suitable arrangements for managing electrical safety.
What Does WorkSafe Say About Visual Inspections?
Visual inspection is an important part of electrical safety.
WorkSafe encourages businesses and equipment users to regularly look for obvious signs of damage or deterioration.
Examples include damaged plugs, cracked insulation, exposed conductors, loose components, overheating and damaged extension leads.
A test tag should never be treated as permission to continue using visibly damaged equipment.
If equipment appears unsafe, it should be removed from use until it has been appropriately assessed.
An electrical test provides information about equipment condition at the time of testing — not a guarantee of future safety.
What About Residual Current Devices (RCDs)?
Residual Current Devices, commonly called RCDs, provide an important additional level of protection against electric shock.
An RCD monitors electrical current and disconnects the supply when it detects certain fault conditions.
WorkSafe highlights the importance of RCD protection, particularly where electrical equipment is used outdoors, in damp conditions or in other circumstances requiring additional protection.
An appliance passing an electrical safety test does not remove the need for appropriate RCD protection.
Likewise, having an RCD installed does not mean damaged electrical equipment can safely remain in use.
AS/NZS 3760 includes provisions relating to the inspection and testing of RCDs.
Official WorkSafe resource: WorkSafe – Cords, Plugs and RCDs
What Does WorkSafe Say About Electrical Safety on Construction Sites?
Construction and demolition sites present additional electrical risks.
Electrical equipment may be exposed to moisture, dust, physical damage, heavy use and frequent movement between locations.
WorkSafe provides specific guidance on managing electrical safety on small construction sites.
This includes considering temporary electrical supplies, distribution equipment, extension leads, RCD protection, equipment condition and inspection arrangements.
AS/NZS 3012:2019 provides requirements relating to electrical installations and equipment used on construction and demolition sites.
The requirements for construction environments can be more demanding than those applying to equipment used in low-risk offices.
→ Read our AS/NZS 3012:2019 guide
Official WorkSafe resource: WorkSafe – Electrical Safety on Small Construction Sites
How Often Should Construction-Site Equipment Be Tested?
Construction equipment is commonly subject to shorter inspection and testing intervals because of the conditions in which it operates.
For many categories of portable electrical equipment used on construction sites, a three-month testing cycle is commonly applied under AS/NZS 3012.
However, the precise requirements depend on the equipment, installation and applicable provisions.
A test tag is only one part of electrical safety management.
Equipment should also be visually checked, appropriately protected and removed from service if defects are identified.
Businesses should ensure their inspection arrangements reflect the actual worksite conditions and relevant requirements.
What About Extension Leads and Portable Power Equipment?
Extension leads, portable socket-outlet assemblies and other temporary electrical equipment can be particularly vulnerable to damage.
Common problems include damaged insulation, crushed cables, loose connections, overheating and exposure to moisture.
WorkSafe's construction-site guidance addresses the importance of appropriate electrical supplies, RCD protection and equipment maintenance.
A lead that was safe when tested may become unsafe through subsequent use.
This is why regular visual checks remain important even where periodic electrical testing is undertaken.
What Does WorkSafe Say About Imported Electrical Appliances?
Electrical appliances and fittings supplied in New Zealand must meet applicable electrical safety requirements.
WorkSafe's Energy Safety guidance explains that manufacturers, importers and suppliers have responsibilities relating to product safety and compliance.
An electrical appliance purchased overseas may not automatically meet the requirements applying to products supplied in New Zealand.
For example, an appliance may have a plug that fits a New Zealand socket but still present issues relating to electrical construction, voltage, certification or other product requirements.
Importantly, passing an AS/NZS 3760 electrical safety test does not automatically establish full product compliance.

What About Second-Hand Electrical Equipment?
Second-hand electrical equipment can present additional safety considerations.
An appliance may have experienced years of use, repairs, damage or deterioration before being offered for sale.
WorkSafe advises consumers to consider the electrical safety of second-hand appliances, including the condition of cords, plugs and safety features.
AS/NZS 5761 provides a framework for the inspection and testing of second-hand electrical equipment.
However, electrical testing does not necessarily establish compliance with every product safety requirement that may apply.
Official WorkSafe resource: WorkSafe – Electrical Equipment and Appliances
What About Electrical Safety in Boats, Caravans and Motorhomes?
Electrical installations in boats, caravans and motorhomes can present additional safety risks because of their operating environments and the use of external electrical supplies.
WorkSafe's Energy Safety information includes guidance on electrical and gas safety requirements for recreational vehicles and boats.
These requirements can involve electrical installations, shore-power connections, supply leads, RCD protection and Electrical Warrants of Fitness.
Different standards apply depending on the type of vehicle or vessel and the installation involved.
For example, AS/NZS 3004.2 addresses electrical installations in boats.
→ Read our AS/NZS 3004.2 guide

What About Electrical Repairs and Electrical Workers?
WorkSafe distinguishes between routine electrical safety inspection and work that must be carried out by an appropriately authorised electrical worker.
Electrical Test & Tag can be undertaken by a person with the necessary knowledge and skills to perform the inspection and testing correctly.
However, identifying an electrical fault does not automatically authorise the tester to repair it.
Electrical repairs and prescribed electrical work must be undertaken by people who meet the applicable legal requirements.
For businesses, this distinction is important when deciding whether equipment requires further inspection, repair or replacement.
Official WorkSafe resource: WorkSafe – Who Must Comply With Electrical Safety Requirements?
What Happens if Electrical Equipment Is Unsafe?
Electrical equipment identified as unsafe should not continue to be used simply because it has a current test tag.
Depending on the defect, the equipment may need to be disconnected, removed from service, repaired or replaced.
WorkSafe's guidance emphasises that equipment must remain electrically safe throughout its use.
Where repairs are required, the work must be undertaken by an appropriately authorised person.
Inspection and maintenance records can help businesses identify defects and document the corrective action taken.
What About Electrical Accidents and Incident Reporting?
Electrical accidents can result in electric shock, serious injury, fire, property damage or death.
New Zealand legislation requires certain electrical accidents and incidents to be reported to WorkSafe.
The reporting requirements depend on the circumstances, including whether the accident occurred in a workplace, the severity of the incident and the nature of the electrical hazard.
What Electrical Accidents Must Be Reported?
Notifiable electrical accidents can include incidents involving serious injury, death or significant property damage.
WorkSafe provides separate notification processes for workplace and non-workplace electrical accidents.
Businesses should understand their reporting obligations and ensure appropriate procedures are in place for responding to serious electrical incidents.
What About Unsafe Electrical Appliances?
An electrical appliance does not have to cause an accident before a safety concern can be reported.
WorkSafe's Energy Safety team accepts reports concerning potentially unsafe electrical and gas products.
This may include appliances with suspected electrical safety defects or products that present a risk to users.
Electrical equipment identified as unsafe should be removed from use until appropriately assessed.
What About Dangerous Electrical Installations?
WorkSafe also provides an Installation Fault Notice process for electrical or gas installations presenting safety concerns.
This process is particularly relevant to electrical workers who identify dangerous installation conditions.
It is separate from routine electrical appliance inspection and testing.
Where Can Electrical Accidents and Safety Concerns Be Reported?
WorkSafe provides official reporting information and notification processes for different types of electrical incidents.
Official WorkSafe resources:
- Electrical and Gas Event Notification
- Reporting Unsafe Electrical Products
- Installation Fault Notices

What Does WorkSafe Say About Workplace First Aid?
WorkSafe New Zealand provides guidance on workplace first aid equipment, facilities and access to trained first aiders.
Under New Zealand's workplace health and safety framework, businesses must provide first aid arrangements appropriate to their workplace risks.
WorkSafe recommends regularly checking first aid kits, replacing used or expired supplies and ensuring equipment remains accessible and suitable for the workplace.
Through Swap-A-Kit, NZ Test Group provides a practical kit exchange and replenishment solution designed to help businesses maintain their workplace first aid supplies.
