Common Electrical Problems in Older Auckland Homes

Auckland is full of charming older homes — villas, bungalows, and early mid-century houses that have real character. But behind their beautiful facades often lie outdated electrical systems that can cause safety issues and costly repairs if left unchecked. At Capita Electrical, we regularly help homeowners across Auckland identify and fix common electrical problems in older properties to keep them safe, functional, and compliant.

1. Outdated Wiring

Many older Auckland homes still have original wiring — often rubber or cloth-insulated cables — which deteriorate over time. As the insulation breaks down, the risk of short circuits and electrical fires increases. Modern TPS (thermoplastic-sheathed) wiring is far safer and more efficient. If your home hasn’t been rewired in decades, it’s time for a professional inspection and potential electrical rewiring.

2. Insufficient Power Outlets

Older homes were never designed for today’s tech-heavy lifestyles. You might find yourself relying on multiple power boards or extension cords just to plug everything in. Installing additional outlets — especially in kitchens, living areas, and home offices — not only makes life easier but also reduces the fire hazard caused by overloaded circuits.

3. Blown Fuses and Tripping Circuit Breakers

Frequent power trips or blown fuses are a clear sign your home’s electrical load exceeds what the system was designed to handle. This can point to outdated switchboards, faulty wiring, or overloaded circuits. Upgrading to a modern switchboard with safety switches (RCDs) is one of the best ways to improve both safety and performance.

4. Lack of Earthing

Some older homes were built without proper electrical earthing — meaning that in a fault situation, electricity has no safe path to the ground. This poses a serious electrocution risk. A qualified Auckland electrician can test your home’s earthing system and install grounding where needed to bring your wiring up to current safety standards.

5. Flickering Lights or Power Fluctuations

If your lights flicker or dim when large appliances turn on, it could indicate loose connections, corroded wiring, or an overloaded circuit. These are warning signs that should never be ignored — call an electrician to investigate before the issue worsens.
