Electrical Safety & Compliance for New Zealand Businesses
Ensuring your workplace is electrically safe is a core responsibility under the Health and Safety at Work Act 2015. As of 2026, all New Zealand businesses must strictly adhere to the updated AS/NZS 3760:2022 standards to protect staff and visitors from electrical hazards.
Why Testing and Tagging is Essential for Compliance
While testing and tagging is the primary method for a Person Conducting a Business or Undertaking (PCBU) to demonstrate "practicable steps" for equipment safety, it also provides several business benefits:
- Legal Compliance: Meets requirements set by WorkSafe New Zealand and the Electricity (Safety) Regulations 2010.
- Risk Mitigation: Significantly reduces the likelihood of electrical fires, shocks, and workplace accidents.
- Insurance & ACC Levies: Many insurance policies require proof of regular testing. Compliant businesses may also be eligible for ACC levy discounts.
NZ Test and Tag Intervals by Industry
The frequency of testing depends on your specific work environment and the risk level of the equipment.
| Industry / Environment |
Recommended Testing Interval |
| Construction, Mining, & Demolition |
Every 3 months (Strict quarterly requirement) |
| Factories, Warehouses, & Production |

What Equipment Needs to Be Tested?
In accordance with AS/NZS 3760:2022, if an appliance has a flexible cord and a removable plug, it requires testing. This includes:
- Portable Tools: Drills, grinders, and battery chargers.
- Office Tech: Computers, monitors, and printers.
- Kitchen Appliances: Kettles, toasters, and microwaves.
- Leads & RCDs: Extension leads, power boards, and Residual Current Devices.
Compliance in 2026: Important Changes
The 12-month transition period for the 2025 Electrical Safety Amendments concludes on November 12, 2026. After this date:
- All new electrical installations and certifications must follow the updated standards.
- PCBUs must ensure testing records align with the AS/NZS 3760:2022 edition.
- Record Keeping: You must maintain a detailed asset register, including test results and repair logs.
Next Steps for NZ Business Owners
- Conduct a Risk Assessment: Identify high-risk "hostile" environments in your workplace.
- Hire a Competent Person: Use a professional service like Wilkin Systems, or train a staff member through a certified course.
- Establish a Schedule: Set up automated reminders to ensure you never miss a re-test date.
