Test and tag interval calculator.
Pick where the equipment is used and when it was last tested. The calculator shows when it's next due, using the intervals in AS/NZS 3760:2022.

General information, not legal advice. Always check the current edition of AS/NZS 3760 and your state or territory's electrical safety and WHS regulator.
Re-test intervalsby environment.
These are the intervals the calculator uses. The environment depends on how the equipment is treated, not the type of building.
| Where the equipment is used | Typical interval | Source |
|---|---|---|
| Factory, workshop, manufacture, repair or assembly | Every 6 months | AS/NZS 3760:2022 |
| Commercial cleaning equipment | Every 6 months | AS/NZS 3760:2022 |
| Flexed in use, open to abuse or in a hostile environment | Every 12 months | AS/NZS 3760:2022 |
| Residential-type areas of hotels, motels, hostels and halls | Every 2 years | AS/NZS 3760:2022 |
| Not flexed, not open to abuse, not in a hostile environment | Every 5 years | AS/NZS 3760:2022 |
| Construction or demolition site | Every 3 months | AS/NZS 3012 (commonly 3 months) |
| Hire equipment | Every 3 months | Commonly 3 months |
Equipment that has been repaired, serviced or bought second-hand should be inspected and tested before it goes back into use, whatever its last test date. AS/NZS 5762 covers testing after a repair.
Not sure which row a client's site belongs in? Agree the environment with the client up front and write it down against the site, because that decision drives every due date that follows. Our test and tag frequency guide explains each row in plain English.
Hundreds of items,every due date tracked.
A calculator is fine for one item. For a whole register, Koalaris sets every item's next due date the moment a test is saved, and shows what's due across every client and site, weeks ahead.
Test and tag intervals,answered plainly.
How is the next test date worked out?
The calculator adds the re-test interval for the environment you pick to the date of the last test. If the test was on the 31st and the due month is shorter, it uses the last day of that month.
Is a 12-month interval right for an office?
Often, yes. AS/NZS 3760 bases the interval on how the equipment is treated, not the type of building. A cord under a desk that gets run over by chairs is open to abuse, so it belongs in the 12-month row rather than the 5-year one.
Can I test more often than the calculator says?
Yes. The intervals are the indicative ones in the standard. Under work health and safety law the business manages its own electrical risks and can choose a shorter cycle.
What about construction sites and hire equipment?
Construction and demolition sites follow AS/NZS 3012, which works to a much shorter cycle, commonly every 3 months. Hire equipment is inspected before every hire and commonly tested every 3 months. Check the current standard and your state's rules for both.
Does this work in New Zealand?
Yes. AS/NZS 3760 is a joint Australian and New Zealand standard, so the same intervals apply on both sides of the Tasman.
Is the calculator free?
Yes, and there's nothing to sign up for. You're welcome to link to it from your own website, newsletter or toolbox talk notes.
