Understanding Test and Tag Colour Codes in New Zealand

Colour-coded tags are commonly associated with construction and other managed testing programs. The colour can help identify a testing period, but the exact system should be confirmed for the site and current requirements.

What colour coding is for

A colour system can make it easier for supervisors and workers to see whether equipment appears to belong to the current testing period. It is an administrative aid, not proof that an item has remained undamaged since testing.

Do not rely on colour alone

Always read the actual tag information where needed. A correct colour does not tell you whether the item has been damaged after testing or whether it belongs to the current workplace.

Site-specific rules matter

Construction sites and principal contractors may specify their own process based on the applicable standard and project requirements. Staff should follow the current site procedure rather than a chart saved from an unrelated project.

Replace damaged or unreadable tags appropriately

If a tag is missing or unreadable, do not guess the result from memory. Check the asset record or arrange the appropriate follow-up so the equipment status remains clear.

Records support the visual system

A good register lets the business verify the equipment identity and test history instead of relying entirely on tag colour.
