I'm a sole-trader electrician. Is Kākāriki right for me?+
On commercial subcontract work, yes. Kākāriki is built for sole traders and small firms working under a Main Contractor's H&S framework. If you're doing direct residential work with no Main Contractor above you, Whero is the right tier.
The Main Contractor sent me their SSSP template. Why do I need OHC's?+
Their template may be generic (a form to fill in) or trade-neutral (covers any subcontractor). OHC's pack is electrical-specific — your hazard register lists electrocution, arc flash, capacitor discharge, working near energised assets. Their template lists generic construction hazards. Submit OHC's to evidence you've thought about your trade's specific risks; reference theirs where it covers site-wide rules.
Will the Main Contractor accept this?+
Designed to be accepted. The §2.1 PCBU duties list, §3 Roles table, §23 Sign-Off block, and the HSR Schedule 2 reference all match what Main Contractors look for. If a specific Main Contractor wants additional content (their own induction certificate attached, their own permit-to-work form referenced), you add that as customisation — but the core document doesn't need it.
My EWRB licence is in my name personally. The SSSP is by the firm. Does that work?+
Yes. The SSSP is the firm's site-specific safety plan; the EWRB licence is your personal authorisation to perform prescribed electrical work. The §16 Training Register documents the EWRB Practising Licence of each licensed person on the job (with their licence number and current expiry), and §16.1 spells out that the licence must be current at site induction.
I'm a tier-1 electrical contractor doing $5M+ commercial work. Should I be Kōwhai instead?+
Probably — if you have a documented company-level H&S management system (written policy, training matrix, internal audit cycle), Kōwhai better fits the parallel-PCBU-2 framing. Kākāriki assumes you're adopting the Main Contractor's framework rather than running your own.
Does it cover PV / solar work?+
Yes. The §12 Electrical Safety section covers PV/DC isolation under AS/NZS 5033 + AS/NZS 4777, and the §13 Working at Heights section covers roof PV install. Falls during rooftop PV is one of the 30 hazards in the register.
