New World customers are struggling to get their hands on Smeg kitchenware, available under a 12-week promotion.
They can collect one sticker for every $20 spent.
But the highest-value option, the braiser, is running out - and New World says there won't be any extra deliveries.
Consumer NZ, CEO Jon Duffy, says New World has specified this is 'while stocks last'.
But he says it's also required by law to have appropriate stocks.
"With these promotions, this is not their first rodeo, they've done these over the years - so they do know that these promotions are popular."
