Low user or standard plan: which NZ tariff is cheaper in 2026?
For nearly two decades the advice on this was stable: if you do not use much power, get on a low-user plan. That advice is now out of date, and following it can cost you money. The regulation that made low-user plans attractive has been unwound step by step, and in 2026 the sums land in a very different place.
The short version: the break-even has fallen from roughly 8,000 kWh a year to around 4,000. Since a typical NZ household uses about 7,100 kWh, most homes that were correctly on a low-user plan a few years ago should now be on a standard one.
How the two structures work
Your bill has two parts: a daily fixed charge you pay no matter what, and a variable charge for each unit (kWh) you actually use. The two plan shapes trade these off:
- Low user: a lower daily charge, but a higher c/kWh on the units.
- Standard: a higher daily charge, but a lower c/kWh on the units.
The daily charge is the same whether you burn 5 kWh or 50 kWh, so a household using very little power wants that fixed part small. A household using a lot wants the per-unit rate low, because that is where most of its bill lives. The whole question is where the crossover sits - and that has moved.
What actually changed
Under the Low Fixed Charge Tariff Option regulations, retailers had to offer qualifying households a plan with a daily charge capped at 30c/day. That cap is being removed in annual steps:
| From | Cap |
|---|---|
| Before 2022 | 30c/day |
| 1 April 2022 | 60c/day |
| 1 April 2023 | 90c/day |
| 1 April 2024 | $1.20/day |
| 1 April 2025 | $1.50/day |
| 1 April 2026 | $1.80/day |
| 1 April 2027 | Regulations revoked |
Two things follow. First, a low-user daily charge that was 30c in 2021 can legitimately be six times that today, which wipes out most of the advantage. Second, from 1 April 2027 the regulations disappear altogether and retailers are no longer obliged to offer a low-user option at all. This is an MBIE and Cabinet decision, not an Electricity Authority one.
A worked comparison at 2026 rates
Take two plausible plans: a low-user plan at $1.80/day and 42.0c/kWh, and a standard plan at $2.80/day and 33.0c/kWh. The fixed-charge gap is now only $1.00/day, or $365 a year, while the unit gap is 9c/kWh.
| Annual usage | Low user | Standard | Winner |
|---|---|---|---|
| 3,000 kWh (bach, small flat) | $1,917 | $2,012 | Low user, $95 |
| 4,000 kWh (crossover) | $2,337 | $2,342 | Line ball |
| 5,000 kWh | $2,757 | $2,672 | Standard, $85 |
| 7,100 kWh (NZ average) | $3,639 | $3,365 | Standard, $274 |
| 11,000 kWh (large all-electric) | $5,277 | $4,652 | Standard, $625 |
The crossover is $365 ÷ 9c = about 4,056 kWh a year. Under the old 30c cap the same two plans would have crossed over near 8,000 kWh, which is exactly where the traditional advice came from. The rule has not changed; the inputs have.
The 8,000 kWh figure is not the break-even
This trips up a lot of people, including plenty of articles still online. 8,000 kWh a year (9,000 kWh in the lower South Island) is the regulatory eligibility threshold - use more than that and a retailer is not obliged to offer you the low fixed charge option. It has never been an economic crossover point. Treating it as one is how you end up on the wrong plan.
Who each plan still suits
- Low user still wins for: genuinely light users under roughly 4,000 kWh a year - baches and holiday homes empty most of the year, single-occupant flats, and homes with gas hot water and cooking doing the heavy lifting.
- Standard now wins for: most ordinary households, including average family homes at 6,000-8,000 kWh. Definitely for all-electric homes, a hot water cylinder, multiple heat pumps, an EV on the charger or a spa pool.
A bach remains the clearest low-user case. Empty 40 weeks a year it uses almost no units, so the daily charge is essentially the entire bill - and you want it as small as you can get.
Read your own usage off a bill
- Find the kWh used on a recent bill and note the days it covers.
- Better, find the "last 12 months" or annual usage summary many retailers print - that averages out winter heating.
- If you only have one bill, multiply by 12 with caution: a winter bill will overstate your annual usage badly.
Then compare the actual plans at your address on Billy or Powerswitch. Because the gap between the two plan types is now so much narrower, the specific rates matter more than the plan label - and it is worth re-checking again after April 2027, when the regulated option ends.
Work out your own number
Enter your appliances and region into the NZ Power Bill Calculator to estimate your annual kWh, then test it against both plan shapes. The glossary explains every line item, and the methodology page shows the arithmetic the calculator uses.
