For NZ electrical contractors who are the Main Contractor on the project — residential rewires hired direct by the homeowner, stand-alone commercial fit-outs where you're the only contractor on site, solar/PV installers engaged by a property owner, switchboard contractors on sole-trade industrial upgrades. Covers HSWA s37 workplace controller duties, subcontractor SSSP acceptance, site-wide induction, and Energy Safety / WorkSafe NZ notification.
Editable DOCX · Instant download · Use across every project you run as Main Contractor · Issue as the framework all PCBU 2 subcontractors on site must work within.
You're the PCBU with management or control of the workplace. You hold the head contract with the Client or Principal. You vet subcontractors before they come on site, you run induction, you accept their SSSPs, you're the WorkSafe NZ notifier for notifiable events. Whero is structurally larger than Kākāriki and Kōwhai because of §2.4 Subcontractor Management with the SSSP Acceptance Log — the artefact a regulator or insurer asks for first when reviewing how you vet PCBU 2s before they start on site.
On a residential rewire or stand-alone commercial job, WorkSafe NZ writes to you when something happens. Your name is on the hoarding, the SSSP cover, the project H&S record. A subcontractor pack doesn't cover that — only a Main Contractor pack does.
6-step subcontractor management process with the SSSP Acceptance Log table. Pre-engagement vetting, SSSP submission, acceptance review, induction protocol, toolbox attendance, incident reporting. This is what an auditor opens first.
HSWA s37 puts the workplace controller duty on the entity running the site. Whero structures that duty into §3 (Roles with Site Manager + Subcontractor Liaison), §17 (Incident Commander), §19 (site-wide toolbox), §21 (site-wide H&S Committee).
If you're an electrical firm on a multi-trade commercial site, you're almost certainly a PCBU 2 — either under the Main Contractor's framework (Kākāriki) or operating in parallel with your own H&S system (Kōwhai). Buy the tier that matches your actual role.

Whero sits at the top of the three-pack ladder. Use it when you're running the site, not when you're subbing in.
The Whero pack was drafted around HSWA s37 (workplace controller duty) with explicit machinery for vetting PCBU 2s and coordinating multi-PCBU work under s34. The §2.4 Subcontractor Management process and SSSP Acceptance Log align with the artefacts WorkSafe NZ inspectors and Site Safe NZ auditors look for when reviewing a Main Contractor's H&S record. Electrical content (hazard register, AS/NZS 4836 arc-flash, EWRB licensing protocol, PV/DC isolation under AS/NZS 5033 + AS/NZS 4777) cross-checked against current NZ standards.
Issue to your electrical subcontractors operating under your H&S framework.
For electrical subcontractors operating their own H&S system in parallel with yours.
