Top Electrical Safety Risks in Older Waikato Homes (And How to Fix Them)

If you live in an older home in Hamilton or the wider Waikato, your electrical system might be hiding serious safety issues. Electrical safety risks are particularly prevalent in such homes because, while the lights may still work, the wiring behind your walls could be outdated, brittle, or simply not up to today’s safety standards. This presents electrical safety risks that are often overlooked.

At 2E Electrical, we regularly carry out maintenance checks in homes built before the 1990s. Not addressing electrical safety risks, many of these houses have never had a full inspection. This can be risky due to potential electrical safety risks.

Common Electrical Hazards in Older Homes

Perished rubber wiring
Often found in houses from the 1950s–70s, rubber cable sheathing becomes brittle over time. This increases fire and shock risk, leading to electrical safety risks.
Old fuse boxes
These may lack RCD (residual current device) protection, which is now required under modern wiring rules.
Missing earth bonding
Bathrooms and kitchens may have exposed metal pipes or taps with no earth protection — a serious safety issue indicating electrical safety risks.
Unrated light fittings
Ceiling lights in older homes often aren’t rated for insulation contact (IC). This creates a fire risk when insulation is added.

Why You Shouldn’t Wait for a Problem to Appear

Electrical faults often go unnoticed until it’s too late. A buzzing outlet or flickering light might not seem like a big deal. However, it could indicate failing components behind the wall, pointing to hidden electrical safety risks.

Preventative electrical inspections can:

Lower your fire risk
Catch hidden faults early
Improve energy efficiency and address electrical safety concerns
Help bring your home up to Healthy Homes standards

For rental properties, regular inspections are part of maintaining compliance with New Zealand’s Residential Tenancies Act.
