Certificate of Verification (COV) by Registered Electrical Inspectors

A Certificate of Verification (COV) is an official document that confirms an existing electrical installation is safe and meets New Zealand standards (AS/NZS 3019). You might also see it called a Periodic Electrical Verification.
