Is electrical testing and tagging compulsory in NZ?

No, not in all industries and environments.

Electrical testing and tagging is compulsory on construction sites, for hire equipment and for items that have been repaired.

The New Zealand HSE Act states that employers are responsible for ensuring a safe place of work and that all plant is maintained and safe to use.  It does not prescribe electrical testing and tagging.

If electrical equipment is in the workplace and testing and tagging is not carried out, a documented risk assessment outlining the level of risk and the proposed controls to be implemented is recommended.
