What the 2025 EWRB and Electricity Safety Regulations changes actually mean for your job
You wear two hats most days — the EWRB-licensed one and the ESR-governed install recorder one. This post is the 5-minute version of what changed for registered electricians in 2025, where the paperwork risk sits now, and how to keep the audit trail straight without a Monday admin pile-up.
The pain
The four things ESR paperwork eats
Every registered electrician recognises at least two of these from the last inspection cycle. They aren't dramatic failures — they're the slow stand-up of admin overhead that nobody scheduled time to fix.
Hand-written Certificates of Compliance
Every CoC starts as a printed form, gets scribbled on in a van, and gets re-typed into a spreadsheet on Monday. By audit time nobody trusts the figures themselves — only that the paper trail exists.
Test records scattered across jobs
A single install may produce insulation resistance, earth continuity, RCD trip-time, and polarity records. They live in three folders, two inboxes, and one memory. An inspector asks for the RCD record from job #5821 and you scroll for an hour.
Inspection-ready bundles take a full day
When WorkSafe or an inspector asks for the records behind a job, you spend a day pulling the CoC, the ESC, the test results, and the photo log into a single PDF. It is the same work, every quarter, manually rebuilt from scratch.
Audit exposure from incomplete paperwork
EWRB complaints, disciplinary records, and ESR non-conformance findings follow paperwork failures that look sloppy only after the fact. The risk isn't the wiring — it's the records proving the wiring was checked.
The regulator split
Two regulators, two hats — EWRB licenses the person, ESR governs the install
A registered electrician is accountable to two frameworks simultaneously. The line between them shapes which paperwork survives a complaint and which disappears — get it wrong and you "comply" with one and breach the other.
EWRB — the person
The Electrical Workers Registration Board licenses the individual electrical worker.
- Who EWRB licenses — registered electricians, registered electrical installers, registered electrical engineers, registered electrical inspectors, and cable jointers, across the five EWRB classes.
- What EWRB regulates — licensing, registration classes, practising licences, competence assessment, CPD obligations, and disciplinary processes for individual electrical workers.
- What EWRB does NOT do — installation safety rules. That's the Electricity Safety Regulations 2010, administered by WorkSafe NZ. EWRB licenses the person; ESR governs the install you're signing off.
ESR 2010 — the install
The Electricity Safety Regulations 2010 govern the install itself.
- The Electricity Safety Regulations 2010 — the technical rules for electrical installation work in NZ, administered by WorkSafe NZ under the Electricity Act 1992.
- Prescribed Electrical Work (PEW) — the work that legally must be done by, or under the supervision of, a registered electrical worker. PEW triggers CoC and ESC paperwork.
- Certificate of Compliance (CoC) and Electrical Safety Certificate (ESC) — the documents the registered electrician issues to the client. CoC certifies the work; ESC certifies the connection. Together they are the auditor-facing record.
- Inspections and audit posture — WorkSafe inspections, mains work audits, and the records inspectors ask for. Retention expectations run for the life of the installation plus several years for installer records.
What changed in 2025
The post-2025 changes that matter in the van
The 2025 shifts that move the needle for practising electricians. Treated at a high level so the framing is durable across legislative rewording — for clause-level specifics, read your EWRB renewal pack and the current ESR amendment directly.
Practising licence & class posture
The practising-licence renewal rhythm and the way classes align with installer scope have continued to tighten. Read each renewal notice carefully — provisional-to-full transitions, additional class endorsements, and any supervisor-of-trainee attestation are all points the 2025 renewal cycle pays close attention to. Photocopying last year's form and hoping is a documented way to lose status.
ESR compliance-side paperwork expectations
The regulator's posture on the CoC and ESC lifecycle has moved from 'filed and forget' toward 'filed, retrievable, and consistent with the install record'. Inspectors increasingly expect the test records, the calibration evidence for test instruments, and a clear chain back to the source job note — not just the dated CoC sitting in a folder.
Retention and audit posture
Retention periods on PEW records and installer signing records have crept upward in practice, even where the formal ESR wording has not changed. The safe read is: treat your records as if WorkSafe may ask in seven years, not three. Storage that rotates off after two years is the failure mode.
WorkSafe inspection rhythm
WorkSafe inspection cycles have settled into a more targeted pattern — sample installs, follow the paperwork trail end-to-end, and ask the technician not the owner. The technicians who keep their own clean records (CoC, ESC, test sheets in one bundle, with provenance) come out of those interviews unscathed. The ones whose paperwork is reconstructed on the morning of the visit do not.
From PGDB to EWRB
Same record-keeping pattern, different trade board
The record-keeping pattern KoruAI is built around adapts across trade boards — the works the same regardless of whether you're working in PGDB, Gas Registration, or EWRB frames. We've published the PGDB-licensed trade’s walkthrough of the workflow; the same workflow fits an EWRB-licensed sparkie once you swap in your CoC / ESC / test record templates.
The workflow
Capture once, generate the CoC + ESC + test record in one pass
The same workflow that drafts a job summary becomes the workflow that drafts a compliance record. The sparkie writes one note — KoruAI drafts against the right ESR template, you approve, the record is filed with provenance. No re-keying, no reconstructing the bundle the night before an inspection.
Capture the job note in one place
A sparkie writes the brief note after the install — same place, every job. Photo of the switchboard, the polarity / earth / insulation / RCD results, and a paragraph on what was done. Captured once, on the device already in the van.
AI drafts the CoC + ESC + test record
KoruAI reads the note and drafts the matching compliance record: Certificate of Compliance, Electrical Safety Certificate, and the test result sheet. Drafted against your templates, mapped to the EWRB classes you're registered under.
You approve the draft
The draft lands in your dashboard with the source note and the test results attached. You read, edit if anything's off, and approve. One approval per record, not one approval per keystroke.
Filed with the install record attached
Every approved CoC / ESC is stored with its draft history, the source job note, and the revision timestamps. When an inspector asks for the bundle behind install #5821, you produce it in seconds — the same record the inspector will read.
