With no set price for RATs, it's up to individual retailers to decide a price, Consumer NZ said.
In Australia, it has recently become illegal for RATs to be sold with more than a 20 per cent markup after the Australian Competition and Consumer Commission received more than 1800 reports of price gouging. One of the worst examples of price gouging was a set of two tests costing up to $500, despite wholesale costs ranging between $3.95 and $11.45 a test.
"It's important to remember that RATs are free for anyone with Covid symptoms, or for positive Covid cases, through your local testing station and participating GPs," Cherry said.
"However, if you do want to have a few RATs up your sleeve for peace of mind, ensure you're purchasing them for a price that is fair."
Warehouse Stationery was found to currently offer the lowest price of tests: $31.99 for a pack of five, which works out at $6.40 per test.
Foodstuffs will sell the Orient Gene Rapid Covid-19 Self Test 5-pack ($32.99 per pack), and the Ecotest Covid-19 Rapid Antigen Nasal Pen 2-pack ($19.99 per pack). These are expected to be available next week.
Chemist Warehouse is selling five-packs of RATs for $44.99 on their website, working out at $8.99 per test.
A pharmacy in Lower Hutt is selling the same five-pack, on pre-order, for $74.99. These work out to be $14.99 per test.
Some pharmacists Consumer NZ spoke to said they would not stock RATs, given they were unable to access them at a competitive price or within a fast enough time frame and didn't want to be seen as "ripping the public off".
