Which supermarket is cheapest in NZ?
Pak'nSave had the cheapest overall food prices in Consumer NZ's June 2026 basket study: a 16-item basket averaging $84.38, about $5 a week cheaper than the average for New World and Woolworths loyalty members. Fresh meat and produce were excluded. Marsonya compares live prices across all three chains for your list.
The same forgetting that fills the waste bin quietly inflates the grocery bill: duplicates bought on a guess, specials missed because nobody knew the cupboard was low, the wrong store chosen for this week’s particular list.
Which is cheaper: Pak’nSave, New World or Woolworths?
Consumer NZ’s June 2026 study gives the bounded answer: across a 16-item basket collected over eight weeks in four cities, Pak’nSave averaged $84.38 — about $5 a week cheaper than the loyalty-member average at New World and Woolworths, with fresh meat and produce excluded. The honest reading: cheapest depends on the list. Chains win different items in different weeks, so a whole-list comparison beats any single crown.
The full Pak’nSave vs New World vs Woolworths comparison unpacks the study’s scope and the store-by-store pricing wrinkles behind the headline.
Why are groceries so expensive in NZ right now?
Concentration is the structural answer: Consumer NZ, citing the Commerce Commission’s third Annual Grocery Report, puts roughly 82% of the New Zealand market with two supermarket groups (2026). Fewer competitors means weaker price pressure. Regulation moves on a scale of years, while a household budget resets weekly — which leaves comparing and switching as the levers a household actually holds.
The structural story — concentration, measured inflation and the cost layers underneath — is unpacked in why groceries cost so much in New Zealand.
How can I cut my weekly grocery bill?
Shop from a list built against what the pantry already holds, so nothing gets bought twice. Compare the whole list’s total rather than a handful of headline items. Treat a special as real only against the item’s normal price. Substitute brands where the cheaper product is genuinely close. Each habit is small; together they compound weekly, on every shop.
Habit by habit, the same ground is covered in how to cut your grocery bill in NZ.

What else do people ask about grocery prices?
How current are Marsonya's prices?
Prices come from each chain's public store listings and refresh on a nightly schedule, so a comparison reflects roughly yesterday's shelf, not last month's survey. Specials are judged against an item's own 30-day average, which exposes a fake markdown instantly.
Does Marsonya get paid by any supermarket?
No. Marsonya is an independent, family-built app from Christchurch with no commercial relationship with Woolworths, Foodstuffs or any retailer. The cheapest store wins the recommendation — no retailer can pay for placement.
Why do prices differ between stores of the same chain?
Pak'nSave and New World stores price individually, so the same item can cost different amounts across town. Woolworths lists national online prices. Marsonya compares at store level, against the stores a household actually uses.
Can Marsonya tell me the cheapest store for my whole list?
Yes. A shopping list can be priced as a single shop at each store, or split across stores when the gaps justify a second stop. Whole-list totals answer the cheapest-supermarket question for one household better than any national headline can.
