CPM Test n Tag and Fire Safety provides professional electrical testing and tagging services in Rosedale and across the upper North Shore, including Albany, Browns Bay, Mairangi Bay, and the surrounding North Harbour area. Our EST-trained, police-checked technicians come to your premises and complete all testing in strict accordance with AS/NZS 3760:2022 — the New Zealand standard for in-service safety inspection and testing of electrical equipment.
Rosedale sits at the heart of one of Auckland’s most established light industrial and commercial corridors. The North Harbour Industrial Estate — still widely known by that name despite the suburb’s official renaming to Rosedale in 2009 — is home to a dense concentration of warehousing, logistics, assembly, manufacturing, and technology businesses. For the operators running those premises, electrical testing and tagging is an ongoing workplace safety and compliance obligation, not a one-off exercise.
Electrical Testing and Tagging Services for Rosedale and North Harbour Businesses
Electrical testing and tagging services — also referred to as portable appliance testing (PAT) or test and tag — involves the systematic inspection and testing of in-service electrical equipment to confirm it meets the safety requirements of AS/NZS 3760:2022. In a working environment, this covers everything from computers, monitors, and kitchen appliances in office and commercial premises to power tools, extension leads, and portable equipment in workshops, warehouses, and light industrial facilities.
Rosedale’s business profile makes it a particularly important market for this service. The mix of logistics operations, light manufacturing, assembly facilities, and technology businesses in the North Harbour precinct means a high density of portable electrical equipment — much of it in demanding operational environments where regular testing is not just a compliance requirement but a genuine safety necessity. The area’s connection to the Albany knowledge economy also brings a significant office and commercial sector, where electrical equipment testing is equally required under New Zealand’s workplace safety obligations.
Why Rosedale and North Shore Businesses Choose CPM
CPM Test n Tag and Fire Safety was founded by Peter and Callum Mahon, with Ann Mahon overseeing administration and franchisee coordination. Peter brings more than 50 years of experience in the electrical industry, holds a Licensed Aeronautical Mechanical Engineer (LAME) qualification, and previously operated at the highest level of one of New Zealand’s largest compliance franchise networks before co-founding CPM. That depth of industry experience underpins the technical rigour and service quality CPM delivers on every visit.
Our Auckland North franchisee serves Rosedale, Albany, and the broader upper North Shore as a dedicated local operator. That means consistent, reliable service from a technician who knows the area — not an operator dispatched from across the city with no familiarity with the local business environment.
CPM is also one of a small number of compliance providers in New Zealand offering both electrical testing and tagging and comprehensive fire safety services — including fire extinguisher inspection, fire hose reel testing, and fire blanket inspection — under one roof. For Rosedale and North Harbour businesses managing multiple compliance obligations across both electrical and fire safety, the ability to coordinate everything in a single visit reduces scheduling complexity and keeps your premises running with minimal disruption.
