If you're a registered electrician in New Zealand, there's a hard compliance deadline on your calendar: 12 November 2026. That's the day the transitional period for the Electricity (Safety) Amendment Regulations 2025 closes, and from that date every electrical installation you complete must comply with the updated wiring standards.
Here's what changed, what you need to do, and what happens if you miss it.
What Are the Electricity (Safety) Amendment Regulations 2025?
The Electricity (Safety) Amendment Regulations 2025 came into force on 13 November 2025, updating the references to technical wiring standards embedded in New Zealand's electrical safety legislation. WorkSafe New Zealand oversees enforcement.
The key change is that the regulations now cite newer editions of the core Australian/New Zealand wiring standards, replacing references that had been in place for over a decade. The updated standards include:
- AS/NZS 3000:2018 (Amendment 2:2021) — the main Wiring Rules document covering electrical installation design, wiring methods, and safety requirements
- AS/NZS 3017:2022 — verification of electrical installations
- AS/NZS 3019:2022 — electrical installations and periodic verification
These aren't minor tweaks. AS/NZS 3000:2018 Amd 2, in particular, introduces updated requirements around arc fault detection, enhanced earthing specifications, and revised requirements for submains. Electricians who trained on the 2007 or earlier editions will need to review the changes carefully.
The Transition Period: What's Allowed Now
Between 13 November 2025 and 12 November 2026, New Zealand electricians have the flexibility to comply with either the old or the new standards. In practice, most electricians are still using the legacy standards on existing projects — and that's fine until the deadline.
However, starting any new large-scale project on the old standards now means you'll be mid-build when November 2026 arrives. WorkSafe and Master Electricians NZ have both recommended that electricians begin transitioning to the new standards now rather than waiting for the final deadline.
What You Need to Do Before 12 November 2026
1. Get Access to the Updated Standards
AS/NZS 3000:2018 (Amd 2:2021) is available through Standards New Zealand. A physical copy costs around $350–$420 + GST for the full Wiring Rules. Master Electricians members can access subsidised copies through their membership benefits — if you're not already a member, this is one practical reason to consider joining (annual membership from around $500 + GST for a sole trader).
The standards are copyright-protected and cannot be shared informally between colleagues, so each business needs its own copy.
2. Review the Technical Changes
The main areas affecting day-to-day residential and light commercial work include:
Arc fault detection devices (AFDDs): AS/NZS 3000:2018 Amd 2 expands guidance on where AFDDs are now recommended — particularly in bedrooms and high-risk fire areas. While not yet mandatory in all circuits, the standard sets out conditions where they become a design consideration.
Earthing and bonding updates: Revised requirements for main protective earth connections and bonding in wet areas. Bathrooms, kitchens, and laundries are key focus areas.
Documentation requirements: AS/NZS 3019:2022 tightens what must be recorded during periodic verification. Certificate of Compliance documentation will need to align with the new verification standard.
Submain sizing: Revised tables and calculation methods for submain conductor sizing in larger commercial and multi-unit residential installations.
3. Update Your Certificate of Compliance Templates
The reference standard cited on your Certificate of Compliance (CoC) forms will need to update from the legacy standard references to the new ones once you're working under the new rules. Industry bodies are expected to release updated CoC templates ahead of the November deadline — check with your industry association or Electrical Workers Registration Board (EWRB) for the latest guidance.
4. Train Your Staff and Apprentices
If you run a team, your apprentices and registered electricians will need briefing on the updated requirements. For apprentices still training, the updated standards will likely be incorporated into their course materials — but senior electricians who haven't opened a wiring rules book in a few years may need a formal refresher.
Master Electricians NZ and the Electrical Training Company (ETCO) are expected to run transition training workshops ahead of the deadline. Pricing for half-day workshops typically runs $150–$250 + GST per person.
Enforcement: What Happens If You Don't Comply?
From 12 November 2026, WorkSafe can take action against electricians completing work that doesn't comply with the updated standards. Penalties under the Health and Safety at Work Act 2015 and Electricity Act 1992 are serious:
- Infringement notices: From $500 for minor breaches
- Prosecution: For serious failures, fines for individual electricians can reach $100,000, and for companies up to $500,000
- EWRB referral: WorkSafe can refer non-compliant practitioners to the Electrical Workers Registration Board for disciplinary action, including suspension or cancellation of registration
Recent WorkSafe activity shows the regulator is actively monitoring the sector. In May 2026, Citywide Electrical Limited entered an enforceable undertaking with WorkSafe following an arc flash incident — a reminder that electrical safety failures carry real consequences.

Business Checklist for NZ Electricians
Use this checklist to track your readiness before the November deadline:
- [ ] Purchased AS/NZS 3000:2018 (Amd 2:2021) and AS/NZS 3017:2022, 3019:2022
- [ ] Reviewed key technical changes (AFDDs, earthing, submains, documentation)
- [ ] Staff and apprentices briefed on updated requirements
- [ ] CoC template updated to reference new standards (once updated templates are available from EWRB)
- [ ] New projects commenced on updated standards from July 2026 at the latest
- [ ] Transition training booked if needed
Pricing Impacts for Electrical Work
The updated standards don't dramatically change what most residential jobs involve, but there are a few cost considerations for clients:
- Jobs requiring arc fault detection devices will see an additional $80–$180 per circuit for the AFDD hardware plus installation time
- Updated documentation and verification for larger installations may add 1–2 hours of admin time to quotes ($120–$180 + GST at typical NZ electrician rates of $120–$150/hr)
If you're updating your quote templates to reflect these changes, see our Electrician Pricing Guide for NZ 2026 for current benchmark rates across different job types.
Managing Your Electrical Business Through the Transition
Apps like Fastcrew can help you track compliance documentation, job notes, and certificates across your team — useful when you're managing multiple projects during a standards transition where some jobs run under legacy rules and new ones must comply with the updated standards.
Keeping clear job records now will also make any future EWRB or WorkSafe audit significantly smoother.
