When modifying existing machinery or installing new machinery, it is
your responsibility as an employer to determine if a pre-start health
and safety review is required.
In general, any new machine not certified with a letter of
declaration from the manufacturer or an existing machine being modified
requires a pre-start health and safety review if a provision and a
circumstance from Ministry of Labour Regulation 851, Section 7 applies.
If you are a machine manufacturer, you may have been requested by a
client to satisfy all applicable requirements for machine safeguarding.
Your course of action would be the certification approach, providing
your client with a letter of declaration. In this scenario a machine
assessment is required.
