KeteFrequently Asked Questions
Every day. Prices are collected daily, so what you see is a snapshot of the current prices on each supermarket's website.
In practice, a product's price is usually the same across stores of the same supermarket on the same island, so Kete records one price per product per supermarket per island. The store shown alongside a price is a reference for where you'd shop — the price applies to the island, not to that particular store. Woolworths prices are based on their delivery suburbs, so the label reflects the suburb the price came from.
Prices are collected from publicly available information on supermarket websites. Kete isn't affiliated with any supermarket chain.
A product only shows a price for supermarkets that actually stock and price it. We also only show products that are priced at all three supermarkets in the movers lists and category browse, so comparisons stay apples-to-apples.
Price drops and rises compare a product's latest price against its previous price at the same supermarket. "On special" products are those where the current price is below the product's standard price. The movers lists show only non-sale moves of 3% or more, so routine special pricing doesn't flood the list.
A fixed 16-item basket of everyday groceries — the same basket Consumer NZ uses when comparing supermarkets — that Kete prices at all three chains every day. The home page shows the running total for each supermarket, plus a 90-day trend of how the basket's cost is moving.
No — search, compare and track prices without one. An account is free and optional: it adds a personal dashboard and account settings, like changing your password. Your store selection is remembered in your browser either way.
At the moment, Kete is a website that works well on phones, tablets and desktops. You can scan a product's barcode with your phone's camera right in the browser — no app download needed.
Prices are snapshots of what each supermarket's website shows on the day they're collected. They're a great guide for planning a shop, but prices can change between collections — always check the shelf price before you buy.
For now, yes — Kete is free to use, with no subscription and no advertising. If that ever changes, we'll be upfront about it.
