Frequently Asked Questions
Every day. Prices are collected daily, so what you see is a snapshot of the current prices on each supermarket's website.
Kete records prices per store — every supermarket is checked at each of its stores, so the price shown is the price at that particular store. The store label tells you exactly where that price came from; Woolworths prices come from its delivery stores, so its label names the store.
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. Browsing and search list products once they have a recent price, even when only one supermarket carries them — private-label and single-chain lines are included. Supermarkets without a price for that product simply show no number.
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 Kete Index 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.
Kete is a website that works on phones, tablets and desktops. You can scan a product's barcode with your phone's camera right in the browser. To keep Kete on your phone, install it from the browser prompt on Android; on iPhone or iPad, open Kete in Safari, tap Share, then Add to Home Screen.
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.
