Power Logging and Electrical Energy Audits in Auckland

Energy and Power Logging for Auckland Businesses

The Conduction Company's energy and power logging is an electrician's investigation of your electricity use, measured at your main switchboard. It suits offices, warehouses, workshops, and any site where the power bill has outgrown the business, on single-phase and three-phase supplies alike.

A Calibrated Fluke 1732 on Your Switchboard

The Conduction Company uses its own calibrated Fluke 1732 energy logger. Fluke's specifications say it records voltage, current, power, power factor, and energy on single-phase and three-phase supplies, at intervals as short as one second.

A Full Week on a Commercial Site

The Conduction Company logs a commercial site for a full week, so the graph covers every working day, every night, and the weekend. Fluke's own guidance agrees: for a business that works five days and stops at the weekend, “a seven day survey will most likely capture typical conditions.”

Every Circuit Tested as It Comes On

A logger on the mains sees the whole site, not the individual machines. So an electrician from The Conduction Company switches loads on one at a time and records what each circuit draws. That is how the graph gets names: the heat pumps, the lighting, the hot water, the compressor.

A Report You Can Act On

At the end, The Conduction Company gives you a report with your usage graphs and its recommendations: what is wasting power, and what it would fix to stop it. Any fix is quoted separately, so you decide what goes ahead.

Connected Safely by a Registered Electrician

The logger connects to live conductors inside your switchboard. The Conduction Company sends a registered electrician to do it, working to AS/NZS 4836, the safe-work standard for low-voltage electrical work, which says a competent person must decide the work is safe before it starts.

The Fixes The Conduction Company Installs

Most of what the logger finds is power used when nobody needs it. The Conduction Company fixes that with simple controls, fitted on the circuits themselves or in the switchboard.

Lighting Sensors

Occupancy sensors turn lights on when someone walks in and off once the space is empty. EECA recommends them for warehouse aisles, store-rooms, and bathrooms. The Conduction Company fits them wherever the logging shows lights burning in empty spaces, the same controls it installs in its office lighting upgrades with occupancy sensors.

Time Clocks

A time clock switches lights, heating, and equipment off at a set time every day, with nobody having to remember. EECA says setting heating and cooling to run only when a building is in use can save 10 to 30% of heating and cooling energy. The Conduction Company sets the times from what your logging graph shows.

Master Switches

One switch by the door kills every light in an area, so nothing runs overnight once the last person leaves. The Conduction Company's logging shows how much is running after hours, so you can see what a master switch is worth before you pay for one.

Switchboard Automation Controls

Automation controls in the switchboard turn air conditioning, lighting, and heating off outside the hours a site is occupied. The Conduction Company installs them for commercial clients, and they are the fix behind the largest saving on this page.

What the Work Looks Like on Real Auckland Sites

A Commercial Client with 30 Staff

A commercial client of The Conduction Company had 30 staff and a problem most workplaces will recognise. In the words of Jordan Statham, The Conduction Company's director, “at least 5 ACs and multiple lights were being left on overnight by staff just forgetting before leaving for the day.” The Conduction Company installed automation control devices in the switchboard for under $2,000 including GST, equipment and installation together. They now turn the air conditioning, lighting, and heating off automatically when nobody is there, and the client started saving over $5,000 a year including GST. Those are Jordan's figures from that job, not a promise for yours.

An Auckland Training Provider's Henderson Campus

The Conduction Company carried out an energy consumption investigation at an Auckland training provider's Henderson campus in 2024. Sixteen days after the report, it quoted the fix for the automotive workshop: eleven old gas-discharge high-bay lights replaced with LED, and the switchbank split so the workshop lighting could be switched in zones. The campus approved the work. The Conduction Company does the same kind of lighting upgrades for homes and businesses across Auckland.

Power Logging for Homes

The Conduction Company logs homes too, for 24 to 72 hours, on single-phase and three-phase supplies. It is worth doing when the bill has climbed and nobody in the house can say why.

Logged usage is how The Conduction Company sizes home solar, explained in its guide to solar panel costs, sizes and payback in Auckland.

Why Is My Power Bill So High?

Check the units on your bill before the dollars. If the kWh has stayed flat, the price has gone up: MBIE figures show the average residential price per unit rose about 30% in the five years to March 2026, and comparing plans on Powerswitch may help more than any electrician. If the kWh has climbed, something is using power it did not use before, and The Conduction Company's logging finds it.

What Uses the Most Power in a House?

Usually heating and hot water. EECA says water heating makes up around a third of household energy bills. After that it depends on the house: heat pumps and air conditioning, heated towel rails, underfloor heating, a pool pump, or an EV charger. The Conduction Company's logging shows which of those is driving your bill, because the electrician tests each one as it switches on. The Conduction Company's guide to what uses the most power in a house in NZ covers each load, what it costs to run, and the faults that burn power unseen.

Your Smart Meter Shows When, Not What

Your power company already holds your usage data, often in half-hour blocks. The Electricity Authority says retailers must give you up to two years of it within five business days of asking. That shows when you use power, but not which appliance is using it. The Conduction Company's logging adds that part, and your recent bills help, so have them handy for the visit.

What is the average monthly power bill in NZ?

The average New Zealand home paid about $218 a month for power in the year to March 2026, including GST. That is The Conduction Company's reading of MBIE's figures for what households actually paid: about $2,617 a year for about 6,836 kWh, or 18.7 kWh a day.

Bills swing with the seasons. On MBIE's quarterly figures the average was about $272 a month over winter 2025 and about $190 a month over summer 2026. Auckland homes use slightly less power than the national average, 6,832 kWh against 7,010 kWh in 2025 on Electricity Authority figures, so a typical Auckland bill sits about the national average or a little under. If yours is well above that and nobody can say why, The Conduction Company's power logging shows what is driving it.

How can I reduce my power bill?

Start with the hot water cylinder, says The Conduction Company. When it logs an Auckland home with a high power bill, the cylinder is the culprit at least 70% of the time.

Jordan Statham, The Conduction Company's director, points to low-cost fixes first. Cutting shower time by about half cuts how much the cylinder has to heat back up. A cylinder under the house, where it is cold and draughty, wastes less once it is wrapped in insulation or boxed in. Next, put underfloor heating and the cylinder on timers, so they run only when you need them.

Unplugging the TV and chargers at night is not worth the effort. "You'd be looking at cents over the night as opposed to dollars," Jordan says. If the bill is still high and the cause is not obvious, The Conduction Company's logging finds the load that is driving it.

What is a home energy audit?

A home energy audit from The Conduction Company measures where your home's electricity goes, and what is wasting it. A registered electrician connects a calibrated Fluke 1732 logger at your switchboard for 24 to 72 hours, and tests each circuit as it switches on. You get the usage graphs and a report with recommendations, and any fix is quoted separately.

It covers electricity only. A formal energy audit across every fuel a home or business uses is a specialist energy auditor's job.

How to do an energy audit of your home?

Start with your bill, then measure, The Conduction Company advises. Check the kWh on the bill, not just the dollars: if the units have stayed flat, the price went up, not your usage. Your power company holds your usage data and must give it to you when you ask, which shows when you use power. Then borrow the free HEAT kit from Auckland Libraries, whose plug-in meter measures anything that plugs in.

A plug-in meter cannot see the big wired-in loads: the hot water cylinder, heat pumps, underfloor heating, the oven, or the lighting. For those, The Conduction Company logs your home at the switchboard and tests each circuit as it comes on.

What is an energy audit for a commercial building?

For a commercial building, The Conduction Company's energy audit is a week of power logging at the main switchboard. The graph covers every working day, every night, and the weekend, and the electrician tests each circuit to name what is using the power. The report shows what is wasting power and what would fix it, such as lighting sensors, time clocks, or switchboard automation controls.

It is usually a one-off, and it suits a client who owns or occupies the building long term, because the savings build up over years. A tenant on a short lease may not stay long enough to see them. A formal audit across every fuel a site uses is carried out by a specialist energy auditor.
