Every homeowner will encounter electrical issues from time to time. While flickering lights or a tripping breaker may seem like small inconveniences, they often point to deeper safety risks. Understanding the common house electrical problems found in New Zealand homes can help you spot issues early, and know when to call in a licensed electrician.
At Positive Electrical, we don’t just patch up the surface symptoms. Our registered electricians in Whangārei find the root cause of electrical faults, keeping your home safe, compliant, and running smoothly.
Flickering Lights: More Than Just an Annoyance
Flickering lights are one of the most noticeable common house electrical problems. Sometimes it’s as simple as a loose bulb, but frequent flickering may signal:
- Loose wiring connections
- Overloaded circuits
- Issues with the switchboard
If the flickering happens when you use an appliance like the microwave or heat pump, it’s likely your circuit is under strain. Left unchecked, faulty connections and overloaded wiring can increase the risk of electrical fires.
Power Outlets That Don’t Work
Dead outlets are frustrating and a sign something’s wrong. Common causes include:
- Burnt-out connections
- Wiring damage inside the wall
- A tripped safety switch
Instead of relying on extension cords as a quick fix, it’s safer to have an electrician test the outlet and wiring. This ensures you avoid hidden hazards that could cause shocks or overheating.
Circuit Breakers That Keep Tripping
Your circuit breaker is designed to protect you by shutting off power when it detects a fault. If it trips occasionally, it’s doing its job. But if it keeps tripping, the problem could be:
- Overloaded circuits (too many appliances running at once)
- Short circuits from faulty wiring
- An ageing or outdated switchboard
Repeated tripping is not something to ignore. It’s a clear signal that your electrical system needs professional attention.
Overheating Appliances and Burning Smells
If you notice a burning smell, discoloured outlets, or appliances that feel unusually hot, turn off the power immediately. These symptoms often point to:
- Overheating circuits
- Faulty wiring or outlets
- Poor-quality power boards
Electrical fires often start this way. The safest step is to stop using the outlet and call a registered electrician to inspect and repair it before the damage spreads.
Old Wiring and Outdated Switchboards
Many older New Zealand homes still rely on wiring and switchboards installed decades ago. These systems often aren’t designed to handle today’s demand for multiple appliances and devices. Common signs of outdated wiring include:
- Fuse-style switchboards instead of circuit breakers
- Aluminium or cloth-insulated wiring
- Regular power surges or flickering
Upgrading your wiring and switchboard not only prevents faults but also ensures your home complies with modern safety standards. You can read more in our guide to how home wiring works.
When to Call a Professional Electrician
Some minor fixes, like tightening a light bulb, are safe to do yourself. But most common house electrical problems require expert diagnosis and repair. Attempting DIY electrical work is not only illegal in New Zealand – it can also put your safety at risk.
A professional electrician can:
- Identify the root cause of electrical faults
- Upgrade switchboards and rewire outdated systems
- Carry out preventative maintenance for safety and efficiency
- Ensure your home meets NZ compliance standards
