"For companies focused on low prices such as Kmart, it's cheaper and easier to replace an entire product rather than fix it. The few that fail within warranty hit Kmart's bottom line, but the majority that hang on just a bit longer don't cost the retailer a cent. There's no incentive to make products that perform beyond a year or two."
Consumer NZ reported that Smith asked Kmart for a replacement part for the blender and was told no parts were available, being offered a refund instead,
"That's not good enough," wrote Smith.
"I don't want to junk an otherwise fine appliance because one small, easy-to-replace part has failed."
The Herald has contacted Kmart for comment.
Smith said that companies that sell cheap, unsupported appliances have a responsibility to consumers to make more durable products - and to the environment to avoid e-waste.
"Through our Built to Last campaign, we are challenging manufacturers to make more durable and repairable appliances and to provide spare parts at a reasonable cost. We're also changing the way we conduct our testing to introduce reliability scoring, helping consumers to be informed about product durability when purchasing a product," Smith said.
