Hot Work Permit (NZ)

A permit that controls the risk where it actually sits — not during the welding, but in the hour after everyone has packed up and left a smouldering ignition source behind a wall lining.

Hot work is not a statutorily permitted activity in New Zealand the way asbestos removal is licensed — there is no regulation that says you must hold a permit before you weld. The permit exists because insurers, principals and main contractors require it, and because the risk profile is unusual: the dangerous period frequently begins after the work has finished. A permit that is signed on and never signed off has controlled nothing.

Permits are opened and never closed

The close-out and post-work monitoring period is the part that matters. This permit will not close without a recorded final check.

The fire watch is nominal

Naming a fire watch who is also doing the welding is not a control. The permit separates the roles and records both.

Concealed spaces are not checked

Sparks travel through penetrations, cavities and floor gaps. The pre-work assessment covers the other side of the wall, not just the work area.

Who this is for

Welding, fabrication and metalwork contractors
Issue per job where hot work is done outside a designated workshop bay.
Main contractors
Site permit system issued to any trade doing cutting, grinding, welding or brazing.
Building owners and facility managers
Control contractors doing hot work in occupied buildings, where insurer conditions usually require a permit.
Roofing, plumbing and HVAC trades
Torch-on membrane, soldering and brazing all fall inside the definition.

Hot work in a confined space requires both permits. Do not substitute one for the other.

Hot work permitting is a control practice rather than a named statutory document. Its legal weight comes from the general risk-management duties and from the emergency-planning obligation it interacts with.

  1. GRWM reg 6Eliminate the risk where reasonably practicable before minimising itSection 2 — Alternatives assessment
  2. GRWM reg 7Ensure control measures remain effectiveSections 5, 7 and 8 — fire watch, monitoring, close-out
  3. HSWA s36Primary duty of care so far as is reasonably practicableSections 3 and 4
  4. HSWA s34Consult, cooperate and coordinate with other PCBUs where duties overlapSection 1 and Section 6 — issuer is often a different PCBU to the holder

Reviewed by OH Professionals

Written and reviewed by the occupational health and safety team at OH Consultant. Fixed safe-radius and monitoring-duration figures are deliberately not printed into the form. Those values are set by insurers, principals and standards that change, and a permit book asserting an out-of-date figure gives false assurance — the permit records what was applied and why.

Frequently asked

Is a hot work permit legally required in New Zealand?+
There is no regulation requiring a hot work permit by name. The requirement is practical and contractual: insurers commonly make it a policy condition, principals and main contractors require it as a site rule, and the general duty under HSWA s36 to manage risk so far as is reasonably practicable makes a formal control system the expected practice for ignition-source work.
What counts as hot work?+
Any work producing flame, spark or sufficient heat to ignite — welding, oxy cutting, abrasive cutting and grinding, brazing, soldering, torch-on membrane work, and heat guns above the temperatures that ignite adjacent materials. If in doubt, permit it.
How long should the post-work monitoring period be?+
That is set by your insurer's conditions and any applicable standard, and the figures differ. The permit records the period applied and requires interim checks within it to be signed rather than asserting a single number that may not match your policy.
Can the person welding also be the fire watch?+
No, and the permit does not allow it. A person operating equipment behind a welding helmet cannot monitor the surrounding area, which is the entire point of the role.
Do I need a permit in my own workshop?+
Typically not for work in a designated hot work area that has been set up and assessed for the purpose. The permit applies to hot work outside that area — on site, in occupied buildings, or anywhere the surroundings have not already been controlled.
What if hot work is also in a confined space?+
You need both permits, and the confined space controls take precedence. Hot work in a confined space introduces atmosphere risks — oxygen enrichment or depletion, fume accumulation, flammable atmospheres — that the hot work permit alone does not address.
