Our new fridge-freezers test

We’ve changed our test to make it easier to see which fridges deliver on energy efficiency claims.

In our old energy efficiency test we found few fridges used significantly more power than their manufacturers claimed. So we’ve shelved that test and now use a pass/fail assessment. By changing our test we can now test more fridges each year than ever before.

What’s changed?

Our assessment uses the manufacturer’s claimed energy usage. A pass means the measured energy usage was no more than 7.5 percent higher than claimed, anything over that is a fail. Once a fridge fails, we stop measuring. Previously, we would have kept testing to find a maximum energy reading.

Claimed energy use is the amount of energy (in kWh/year) the manufacturer says its fridge uses. If a fridge uses more power than claimed, it’s not necessarily bad, just not as efficient as claimed.

All the fridges we've tested have been updated to use this new pass/fail assessment.

Energy ratings

Refrigeration technology is continually improving. To reflect this, the Minimum Energy Performance Standard (MEPS) and energy-rating labels have been updated.

Since April 2010, updated labels have been required on all new fridges and freezers. Star ratings on new models have been wound back by about 2 stars to encourage greater efficiency. (So a 4-star model on the old label became a 2-star model under the new labels.) It doesn’t mean a model is now less efficient – the star ratings have just been calculated differently. (You can use the kWh/year to compare models, too.)

Super-efficient models that exceed the current 6-star energy rating can achieve up to 10 stars.

MEPS applies to all fridges and freezers made in or imported into New Zealand from 1 January 2005. All models must use no more energy per year than an amount calculated according to their size and type.

MEPS is a requirement manufacturers have to meet. You won't see it on a fridge sales sticker, but better energy efficiency will mean more stars on the energy labels.

Food storage

If you focus entirely on running costs (energy efficiency), you could get a model that doesn't store food well. Remember that energy is used in producing and distributing food too - if you have to throw the food out, that energy will have been wasted.

We test for all aspects of food storage and we only recommend models that'll keep food in good condition.

Buying second-hand

New freezers and fridge-freezers are more energy efficient - so if you're buying second hand, newer is better.

  • Stick to well-known brands under 5 years old, as newer models are much more energy efficient. They’re also easier to get parts for if anything needs fixing.
  • Check the lid or door seal is intact, in good condition and the door or lid shuts properly.
  • Make sure the door is hinged on the correct side for your kitchen (or is reversible).
  • Make sure the interior is in good nick and free from funny smells. Only buy if it looks tidy and well cared for.
  • If you buy a fridge from a second-hand dealer and then discover it’s faulty, you're covered by the Consumer Guarantees Act. If you buy privately, you're not.
  • Under the Electricity Act, all electrical appliances for sale must be safe – whether they're new or second-hand, bought privately or from a dealer.

Environmental issues

Fridges used to be made with and contain environmentally unfriendly CFC gases.

Now, they commonly contain "R134a" refrigerant, which does not damage the ozone layer, although it does contribute to the greenhouse effect. And they are made using ozone-friendly, low greenhouse-effect gases.

A more environmentally sound refrigerant, R600a, is used by some manufacturers. It's a hydrocarbon so it's flammable and therefore carries a small safety risk.

To make the smallest greenhouse-emissions impact over time, a fridge’s energy efficiency is more important than the type of refrigerant used. But if you want to check which refrigerant your fridge uses, all models have this information on the fridge specification plate in the cabinet.
