The Extension Cord Test
Picture this. You've just moved into a freshly renovated home in Richmond. The paint is still faintly sharp in the air, the kitchen benchtop gleams, and you go to plug in the coffee machine — only to find the nearest socket is behind the fridge. Later that evening, you're on the new sofa and end up running a cord across the rug just to charge your phone.
If that scene feels familiar, you're not alone. It's one of the most common regrets Nelson Tasman homeowners tell us about after a build or renovation. You can call it the "extension cord test": if your home needs one to function normally, the power layout was planned for the last decade, not this one.
There's no single legal number, but as a practical planning guide, most modern NZ homes need roughly:
Kitchen: 8–10 outlets across benchtops, island, and appliance zones
Living room: 6–8 outlets, spread around walls rather than clustered in one corner
Main bedroom: 4–6 outlets, including both sides of the bed
Other bedrooms: 3–4 outlets each
Bathroom: 1–2 shaver/appliance outlets outside the wet zones
Home office: 6–8 outlets for desks, monitors, and networking gear
Garage: 4–6 outlets for tools, e-bikes, and workbenches
Outdoor living: 2–4 weatherproof outlets per entertaining area
These figures come from the layout Mako Electrical actually uses as a starting point on new-build projects around Nelson Tasman — not a generic checklist. Read on for the full room-by-room breakdown and what New Zealand's wiring rules genuinely require.
Key Takeaways
There's no legal minimum number of power points per room in NZ — AS/NZS 3000 governs safety, not socket count.
A practical planning guide: 8–10 in the kitchen, 6–8 in the living room, 4–6 in the main bedroom, fewer in secondary rooms.
Bathrooms and outdoor areas have genuine zoning and IP-rating rules that must be followed.
Adding outlets during a build or renovation is far cheaper than retrofitting them later.
All power point installation must be done by a registered electrician and certified for safety.
Planning Your Home's Power Layout: What This Guide Covers
This guide answers one practical question: how many power points does your home actually need, room by room, to keep up with modern life in New Zealand? Whether you're framing up a new build in Richmond, gutting a kitchen in Stoke, or simply tired of daisy-chaining power boards in an older Nelson villa, the number of sockets you install now shapes how your home feels to live in for the next twenty years.
We'll walk through why there's no single "magic number", share the room-by-room spec Mako Electrical uses on new-build projects across Nelson Tasman, and explain what the New Zealand wiring rules actually say about outlets — because it's less prescriptive than most people assume.
How Many Power Points Does a Modern NZ Home Need Per Room?
As a planning guideline rather than a legal minimum, a well-specified modern home in New Zealand typically has:
Important: this table is a practical planning guideline based on how modern households actually use power, not a hard requirement under the New Zealand Building Code or AS/NZS 3000 wiring rules. Those documents focus on safety — circuit loading, earthing, and RCD protection — rather than dictating a minimum socket count per room. We explain exactly what they do cover further down this page.
Why There's No One "Magic Number"
Homeowners often ask us for a single figure: is three power points per room enough? The honest answer is that it depends entirely on how your household lives. A retired couple downsizing near Tahunanui might only need a handful of outlets for lamps and a television. A young family in a new Richmond subdivision, juggling four tablets, two laptops, and a kitchen full of small appliances, needs considerably more.
The biggest mistake we see is homeowners designing to the bare minimum. New Zealand's wiring standards exist for safety, not convenience — so a home can be perfectly legal and still leave you short of sockets. Good electrical design means walking through your floor plan and imagining your actual routines: where the Christmas tree goes, where you'll vacuum the hallway, where a digital photo frame might sit in five years' time.
A Real New-Build Power Point Spec, Room by Room
Rather than repeat generic advice you'll find on any electrician's blog, here's the layout Mako Electrical starts from on new-build homes across Nelson Tasman, then adjusts to suit each family. If you're still at the planning stage, it's worth reading through what to ask your new build electrician before construction starts and how to plan electrical layouts for new build homes alongside this guide.
The Kitchen: Your Home's Power Hub
The kitchen carries the heaviest electrical load in any modern home. Between air fryers, slow cookers, wine fridges, and built-in coffee machines, benchtop appliances alone can eat through six outlets before you've even accounted for the fridge, oven, and dishwasher.
We use a zoned approach: dedicated circuits for heavy fixed appliances, plus pop-up or under-cabinet sockets on the island bench so a laptop or phone charger doesn't need to sit on the stone benchtop. This keeps the kitchen looking tidy while covering everything you'll actually plug in. If your island bench includes a hob, check whether your kitchen island is code-compliant before finalising the layout, and confirm your circuit capacity if you're weighing up an induction hob's electrical requirements.
Living Spaces: Power That Hides Until You Need It
In the lounge, the goal is convenience without visible clutter. We place outlets at different heights: low behind the TV cabinet for the sound system and console, and tucked inside a media unit to keep the router and set-top box out of sight. If you're planning a heat pump or a smart home hub, give it a dedicated outlet rather than sharing one with your entertainment gear — it stops nuisance tripping and keeps both systems running cleanly, and it's worth a read through our guide to home electrical upgrades for modern NZ living before you finalise the plan. It's also a good stage to think about finish, not just function — a growing number of Nelson Tasman homeowners are choosing black nickel or brass power points over standard white for a more considered look.
Bedrooms: More Than a Bedside Lamp
A single outlet behind the bed head is no longer enough. Most people now charge a phone as their alarm clock, so both sides of the bed need an easily reached socket — ideally at bedside table height rather than skirting height, so you're not moving furniture to plug something in. If there's a dressing table, add a spot for hair straighteners or a lit mirror too. Worth a check while you're at it: our guide on spotting a faulty USB power point before it damages a phone or laptop overnight.
Bathrooms and Laundries: Safety First
Bathrooms are the one room where New Zealand's rules genuinely do dictate placement, not just general practice. AS/NZS 3000 sets out strict "zones" around baths, showers, and basins where sockets are prohibited or restricted, and every socket outlet must be RCD-protected. In practice, this usually means one or two shaver-style outlets positioned safely outside the wet zones. For the full breakdown of what's allowed where, see bathroom zones explained. Laundries need a dedicated, adequately rated circuit for the washing machine and dryer, kept clear of splash areas.
Home Offices: Built for the Way We Work Now
With so many Nelson Tasman households working from home at least part of the week, a home office needs real capacity: quad outlets or power points with built-in USB-A and USB-C ports for a computer, monitor, printer, and phone charger without a tangle of adapters. Add a data point alongside the power outlet if you're running a wired network connection.
Garages and Outdoor Living: The Rooms People Forget
Garages increasingly double as workshops and e-bike charging stations, so plan for tool use and overnight charging on separate circuits where possible. Outdoors, weatherproof, IP-rated sockets around a deck or patio cover heaters, speakers, and festive lighting without a cord running under a door — see our tips on outdoor socket installations for deck living. If a spa pool is part of the plan, it needs its own dedicated circuit and isolation switch, covered in our guide to spa pool electrical installation.
Getting the Placement Right
Beyond the count, where you put each outlet matters just as much:
Standard indoor sockets typically sit 300–400mm above the floor, but modern kitchens often place benchtop outlets 100–150mm above the surface for easy reach.
Bedside outlets are usually set to match your furniture height, not the standard skirting height, so you're not stretching over a bedside table.
Outdoor and bathroom sockets need a suitable IP (Ingress Protection) rating to keep out moisture — this isn't optional for weather-exposed or wet areas.
Future-proof key spots now: a power point near a window pelmet for motorised blinds, or a spare outlet near the TV wall for tomorrow's gadget, costs far less to add during a build than to retrofit later.
Enough well-placed outlets also mean you can retire the power boards altogether — see why that matters in our piece on the hidden dangers of daisy-chaining power leads.
What NZ Wiring Standards Actually Say
It's worth being precise here, because a lot of advice online blurs safety rules with design preference. In New Zealand, electrical installations are governed by the AS/NZS 3000 wiring rules (adopted under the Electricity (Safety) Regulations), which cover things like RCD protection on socket circuits, safe circuit loading, earthing, and strict zoning rules in bathrooms. They do not specify a minimum number of power points per room for a standard house.
That means the room-by-room numbers in this guide are a planning guideline built from real project experience, not a code requirement. What the rules do require is that all electrical work is carried out and certified by a registered electrician, so it's tested, safe, and backed by an electrical safety certificate — something worth remembering if you're ever tempted to add a socket yourself. If you're unsure what that certification actually covers, our guides to what a Certificate of Compliance is in NZ and what happens during a professional electrical inspection explain the process in full.
The Benefits of Getting This Right the First Time
Planning your power layout properly, rather than defaulting to the bare minimum, pays off in a few concrete ways:
Fewer extension cords and power boards, which reduces trip hazards and fire risk.
A tidier, more resaleable home — buyers notice when a house has clearly been planned for modern living.
Lower long-term cost, since adding outlets while walls are open during a build or renovation is far cheaper than retrofitting them later.
A home that keeps up with your gadgets, from smart speakers to EV chargers, without constant compromise.

Frequently Asked Questions
-
Costs vary depending on whether the wall is open (during a build or renovation) or already finished, how far the new outlet is from the existing circuit, and your region. Retrofitting into a finished wall generally costs more than wiring during construction. For an accurate figure, request a fixed quote from a registered local electrician before work begins.
-
Outdoor sockets cost more than standard indoor ones because they need a weatherproof, IP-rated enclosure and RCD protection, plus any cabling run to an external wall. Distance from the switchboard and any decking or paving work involved both affect the final price, so it's best confirmed with a site-specific quote.
-
Most straightforward power point additions don't need a building consent, but the electrical work itself must be carried out by a registered electrician and certified with an electrical safety certificate. Larger projects involving new circuits or switchboard changes may trigger other compliance requirements, so it's worth checking with your electrician first.
-
A single additional outlet on an existing circuit in an accessible wall can often be completed within a couple of hours. Jobs involving new circuits, ceiling or floor cavity access, or multiple outlets across several rooms take longer. Your electrician can give you a realistic timeframe once they've seen the site.
-
Check that any electrician you hire is registered with the Electrical Workers Registration Board (EWRB), which you can verify on the EWRB public register. A licensed local electrician will also be familiar with Nelson Tasman's older housing stock and coastal conditions, which matters for outdoor and damp-prone areas.
-
Look for current EWRB registration, a clear written quote, and a written electrical safety certificate provided once the job is finished. It's also worth asking whether they carry public liability insurance and how they handle warranty callbacks, so you're covered if anything needs adjusting later.
-
All socket-outlet circuits in New Zealand homes must be protected by an RCD (residual current device) to guard against electric shock, and bathrooms have strict zoning rules limiting where sockets can be placed near water. Outdoor and wet-area outlets also need an appropriate IP rating to keep out moisture.
-
There's no fixed legal minimum per room. AS/NZS 3000 governs how outlets are wired and protected, not how many you install. The room-by-room numbers in this guide reflect practical, real-world planning based on how modern households use power, rather than a compliance requirement.
-
Yes, and it's common practice. Doubles are usually preferred in high-use spots like kitchen benches and entertainment walls, while singles can suit tighter spaces such as beside a doorway. Your electrician can advise on the best mix based on your furniture layout and appliance needs.
