What is electrical testing & tagging?
Electrical Testing and Tagging is the process by which portable electrical appliances are inspected and tested for safety in accordance with the AS/NZS 3760 Standard. The testing process will include visual inspection, earth continuity, voltage and amperage.
​
According to the 2015 Safety at Work Act, every business in New Zealand has the obligation to provide a safe workplace environment as far as reasonably practicable, and therefore electrical safety is one of the measures you should take to ensure the safety of your employees and visitors.

Who can test and tag electrical equipment in New Zealand?
You do not need to be an electrician to test and tag electrical equipment in New Zealand. According to AS/NZS 3760:2010, someone who is considered a 'Competent Person' is able to test and tag in New Zealand.
This can be achieved by undertaking a test and tag course/training, where you can learn the theory and the skills to use a portable appliance tester machine.

What type of electrical appliances need testing and tagging?
You should test and tag any electrical equipment that is connected to the electrical supply by a flexible cord with a plug. Make sure to include the following in your next inspection:
​
-
Electrical equipment being used for the first time.
-
Electrical equipment that is already in use.
-
Electrical equipment that has received a failed tag and has now been serviced or repaired.
-
Electrical equipment that is being returned to service from a second-hand sale.
-
Electrical equipment that is available for hire.

Also, in most cases, when you are taking your electrical appliances to rest homes and universities, they will request that you have your equipment checked.

How often should I test and tag?
The testing and tagging intervals are mainly determined by the environment and outlined in the AS/NZS 3760 Standard.
The general guidelines of testing and tagging frequency are as follows:
​
-
New electrical appliances should be tested prior initial use.
-
Building, construction & demolition sites should have their tools tested every three months.​
-
Factories, workshops, manufacturing plants should be tested every six months.
-
Equipment used for commercial cleaning should be tested every six months.
-
Commercial workplaces, such as offices should be tested yearly or five-yearly (after assessment).
​
The minimum required standard Interval is set on the AS/NZS3760 Test Interval Timetable. Note that this is a guideline and ultimately the testing intervals or frequencies will vary according to the health and safety risk-assessment management practices of each business.
