Is Your Home Safe? The Reality of Older Wiring
Rewiring is a significant undertaking, but for many older Auckland homes, it’s a non-negotiable safety requirement. If your property still has TRS (Tough Rubber Sheath) or VIR (Vulcanised Indian Rubber) cabling, it is likely a ticking time bomb for your insurance. Most NZ insurers will now refuse cover or cancel policies if these cables aren't replaced, as
the rubber insulation becomes brittle and flammable over time.
This guide is a specialised chapter of our comprehensive Auckland Electrician Cost Guide 2026, designed to help homeowners budget with confidence.
Why Rewiring Costs Vary
The term "rewiring" can mean different things depending on who you ask. At Neon Electrical, we break it down into two levels:
- Internal Circuit Replacement: Replacing the wires behind your walls, switches, and sockets.
- Full Supply Upgrade: This includes the internal circuits plus incoming power lines, consumer mains, earthing systems, and new meter boards.
Average Rewiring Estimates for 2026
While every home is unique, we find that for a standard single-story, 3-bedroom home in Auckland, a full rewire typically averages: $10,000 to $15,000 + GST
- 2-Bedroom Unit: $8,000 – $11,000
- 3-Bedroom Home: $10,000 – $15,000
- 4+ Bedroom / Multi-Storey: $16,000 – $25,000+
Note: This range often includes a modern switchboard upgrade with RCD protection, which is required by law during a full rewire.
The Neon "Inspection Rule"
We do things differently. I will only provide a final, fixed price for a rewire if I can physically get into the ceiling space and under the floor. This is the only way to see exactly what is going on. We need to check:
- Access points for running new cables.
- Whether any sections have already been modernised (saving you money).
- The condition of your mains and earthing.
Beware of "Blind" Quotes
We often compete with companies that provide quotes over the phone without ever looking in the ceiling. This leads to two major problems:
Overcharging: They quote for "worst-case scenario" work that might not even be necessary.
The "Unforeseen" Trap: They give a low price to get the job, then hit you with massive "unexpected" costs halfway through when they realise the job is harder than they thought.
The Smart Way to Rewire: Renovate Simultaneously
The best time to rewire is when you are already planning to paint or renovate. If walls are open, the labor time drops significantly. However, if you're staying in the home, don't worry, we specialise in "clean rehires" where we minimise wall damage using specialised tools to fish wires through existing cavities.
