What is a P.A.T. (Test & Tag) and how often do I need to test my gear?


P.A.T. stands for Portable Appliance Testing but in New Zealand it is commonly called Test and Tag.  Under Section 6c of the NZ Health and Safety at Work Act 2015 and AS/NZS 3760 2010 an employer has a duty to ensure that any portable electrical appliances used by an employee are maintained and tested/checked on a regular basis to ensure their operational safety.


Your power tools and electrical appliances are the bread and butter of your toolkit but in the course of your routine tasks they often get knocked about, often causing considerable wear and tear. 


The AS/NZS 3760 2010 Standard gives the required testing and inspection intervals (as shown in the following exerts from the Act). 


MegaTest recommends using the Testing and Inspection Table to assist you to ensure your equipment is retested in a timely manner, on schedule, ensuring continuity of compliance.


Who needs their equipment test and tagged?


Anybody who is in business and/or employs staff and is wanting to meet current Health and Safety obligations.


Listed below are some of the basic industries as outlined in the act:

  • Construction Sites

  • Factories/ Warehouses

  • Hotels/ Restaurants/ Motels

  • Shops/ Retail/ Offices

  • Schools/ Hospitals


Although the act does not specifically mention residential property, MegaTest strongly recommends that items such as phone or laptop chargers, heaters, small appliances, etc., should also be regularly tested.

We feel that having a contractor working for an hourly rate makes an organisation vulnerable to a potential lack of efficiency. To this end we charge a per tag rate, we will disconnect, test and reconnect equipment in a tidy manner. This also elevates the need of your staff from having to collect and organize the equipment in a specific site or area.


Most of all we strive to deliver a great service in a timely manner by our friendly technicians at a competitive price.

An overview of the Standards affecting Appliance testing include:

(as taken from Standards New Zealand and New Zealand Legislation Government websites - links as referenced below)


This Standard is a revision of AS/NZS 3760:2003, and specifies procedures for the safety inspection and testing of low voltage single phase and polyphase electrical equipment, connected to the electrical supply by a flexible cord and/or connecting device, which is new equipment placed into service for the first time, is already in-service, has been serviced or repaired, is returning to service from a second-hand sale, or is available for hire.

Covers the inspection and testing process to be followed prior to sale of a second-hand electrical appliance so that when the appliance re-enters service, protection against hazards to the user, such as electrical shock, mechanical injury, or electrical fire, is ensured as far as practicable.


This Standard establishes sound practices for the safe use of electricity at construction and demolition sites. It is to be used in conjunction with AS/NZS 3000, Electrical installations (known as the Australian/New Zealand Wiring Rules).

This Standard deals with the safety of microwave ovens for household and similar use, their rated voltage being not more than 250 V, the wattage usage and radiation approved levels.

The main purpose of HSWA is to provide for a balanced framework to secure the health and safety of workers and workplaces by: protecting workers and other persons against harm to their health, safety and welfare by eliminating or minimising risks arising from work
