Does New Zealand require a SWMS?+
No. There is no provision in the Health and Safety at Work Act 2015 or its regulations that requires a Safe Work Method Statement. The SWMS is an instrument of Australian WHS regulation, where it is triggered by a prescribed list of high-risk construction work. New Zealand regulates the same risks through the general duty to manage risk — identify hazards, apply the hierarchy of control, keep controls effective — without prescribing the document.
So what do I use instead?+
Two documents, at two levels. At project level, a Site-Specific Safety Plan, which is what a New Zealand main contractor asks for before you start on site. At task level, a Job Safety Analysis or Task Analysis — the same thing under two names — for each higher-risk task. On a typical job you have one SSSP and several JSAs sitting under it.
What is the difference between a JSA and a Task Analysis?+
Nothing substantive. They are two names for the same instrument and New Zealand uses both. Site Safe material tends to say Task Analysis; many contractors say JSA. Some businesses say JSEA. If a main contractor asks for one and you supply the other in a sound format, it will be accepted.
My Australian head office sent me a SWMS. Can I use it?+
You can use the technical content — the hazard identification and control thinking generally transfers. What does not transfer is the legislative framing: it will cite the WHS Act and Regulations, reference the Australian high-risk construction work list, and use duty language that does not match HSWA. Rewriting it as a JSA against New Zealand legislation is the sensible route.
Is notifiable work the New Zealand version of high-risk construction work?+
They are related but not equivalent, and conflating them causes errors. New Zealand notifiable work — falls of 5 metres or more, scaffolding over 5 metres, certain excavations, explosives, compressed air work and others — triggers a duty to give WorkSafe at least 24 hours notice. It does not trigger a prescribed document. Australian high-risk construction work triggers a SWMS. Different mechanisms, different purposes.
Why do NZ suppliers sell "SWMS templates"?+
Because the search demand exists, largely from people who have encountered the Australian term. Selling the document under that name is not illegal, but it means supplying a New Zealand business with a document framed around a requirement that does not apply to it, which is a poor basis for a compliance product.
