Filing CoC, ESC and electrical records for NZ rentals

Create one electrical folder for each address

Use the full street address and unit number as the primary identifier, with the owner's internal property code as a secondary field. Store electrical records separately from similar-looking documents for another unit in the same development. If a property changes owner or manager, record the handover date rather than renaming old files without context.

Within the address folder, keep an index with the job date, room or circuit, brief issue, work-order number, contractor and status. Link each index row to the supporting files. This makes it possible to trace repeated tripping, a later renovation or a recommendation that was approved in stages.

Know what CoC, ESC and RoI record

EWRB says a Certificate of Compliance records prescribed fixed-wiring work and confirms that the identified work was completed lawfully and tested. An Electrical Safety Certificate is the final safety certification for the connection or completed work to which it applies. The two documents may be combined, but they have different purposes.

Some higher-risk prescribed electrical work also requires independent inspection and a Record of Inspection. Routine maintenance, replacement and repair work does not always produce a CoC. Ask the electrical worker which records apply to the actual scope rather than treating a missing CoC as proof that every small repair is incomplete.

Keep the job context with every certificate

For every electrical attendance, save the tenant or manager report, safe photographs, approved scope, quote or approval limit, access record, dates on site, work description, test outcome, invoice and completion note. Add equipment model and serial details for a heat pump, oven, charger or other connected appliance.

The certificate and work description should identify the installation and describe the work clearly enough to match the property record. If the contractor recommends later work, record the exact item, reason, date, owner decision and next review point. Do not overwrite the original recommendation when the follow-up is completed.

Use consistent filenames and preserve originals

A practical filename starts with the date, then address or property code, job number, document type and short scope. For example, 2026-08-24, Albany unit 3, job 184, ESC, heat-pump circuit. Use the same controlled document labels across the portfolio so CoC is not filed as a generic compliance paper.

Keep the original PDF or image supplied by the electrical worker and store any property-manager notes as a separate file. Back up the folder and control access because it can contain tenant contact and entry information. Retention periods can differ by document and purpose, so follow current legal, accounting and insurer requirements instead of applying the electrical worker's record-retention duty as a universal landlord rule.

Audit open actions before a tenancy or handover

Before a new tenancy, portfolio transfer or renovation, review the index for open safety actions, temporary repairs, repeated faults, missing documents and equipment instructions. Tenancy Services includes records of prescribed electrical work and maintenance or repair work among the documents landlords should keep. The record review supports the next decision but does not replace a current site inspection.
