Consumer NZ is warning that many household appliances actually should last longer than both the warranty and what's expected.

For example, TVs should be providing 8 years of work, and ovens should last for about 15 years.

It wants to see a mandatory 'repairability' rating system introduced, showing how many years an appliance should last - similar to an energy rating.

Consumer NZ Head of Testing Dr Paul Smith joined Heather du Plessis-Allan.
