New Zealand’s supermarket sector remains firmly in the grip of a duopoly dominated by Foodstuffs and Woolworths NZ, fueling accusations of price gouging amid unrelenting food inflation. Households face weekly grocery bills up 25 percent since 2022, with basic items like milk and bread hitting record highs, prompting calls for radical intervention.
Duopoly Structure Explained
Foodstuffs operates Pak’nSave, New World, and Four Square brands across North and South Island co-operatives, while Woolworths runs Countdown and SuperValue. Together, they control over 80 percent of the 25 billion dollar grocery market, with vertical integration into supply chains, distribution, and even fishing fleets.
This concentration enables pricing power unmatched globally. Own-label products like Pams and Homebrand undercut competitors, locking in loyalty. Barriers for entrants—complex logistics, site covenants, and scale economies—stifle rivalry.
Food Inflation Surge
Annual grocery inflation hit 7.2 percent in early 2026, double the overall CPI at 3.5 percent. Fresh produce jumped 12 percent, dairy 9 percent, and meat 8 percent year-on-year. A standard family basket now costs 285 dollars weekly, up from 220 dollars two years prior.
Wage growth lags at 4.1 percent, squeezing disposable income. One in four households skips meals; food banks report 30 percent demand rise. Rural areas suffer most, with transport markups adding 15-20 percent.
| Grocery Category | 2024 Price | 2026 Price | Increase |
|---|---|---|---|
| Milk (2L) | 3.20 dollars | 4.10 dollars | 28% |
| Bread (Loaf) | 2.80 dollars | 3.70 dollars | 32% |
| Eggs (Dozen) | 5.50 dollars | 7.90 dollars | 44% |
| Chicken (1kg) | 9.50 dollars | 12.80 dollars | 35% |
| Apples (1kg) | 4.20 dollars | 5.90 dollars | 40% |
Price Gouging Allegations
Commerce Commission probes revealed supplier squeezes: growers paid 30 percent below costs while retail margins swelled to 25 percent on fresh goods. Woolworths posted 100 million dollars half-year profit in 2025 despite “cost pressures.”
Whistleblowers claim slotting fees—millions for shelf space—and deliberate stock shortages inflate urgency pricing. Kiwis pay 20-30 percent more than Australians for identical products, per consumer trackers.
Greens MP exposes: “Duopoly rakes billions while families ration rice.” Foodstuffs counters with “competitive pricing,” but data shows identical price hikes across banners.
Heinz Wattie’s Closure Fallout
Heinz Wattie’s March 2026 announcement to shutter NZ manufacturing—350 jobs lost—pins blame on duopoly demands. High input costs cited, but analysts trace to squeezed margins: supermarkets demanded 15 percent cuts post-2022 floods.
Bakeries and canneries follow: Griffin’s biscuits mothballed lines; local tomato processing halved. Empty shelves loom for baked beans, soups—NZ manufacturing’s “coffin nail.”
Government Fast-track Approvals Act amendments aim to lure new chains, but critics doubt Aldi or Costco entry without wholesale access.
Government and Regulatory Response
Commerce Commission’s 2022 study labeled competition “seriously deficient,” recommending divestitures. Grocery Commissioner enforces code since 2024, fining poor supplier conduct up to 3 million dollars.
Nicola Willis’ “express lane” for consents targets duopoly break by 2027. Unit pricing mandates and loyalty transparency rolled out, yet prices climb.
Labour pushes public grocery chain; Coalition resists break-up fearing short-term hikes. Three-year review looms late 2026.

|---|---|---|
| 2023 | Grocery Code Introduced | 50 probes, minimal fines |
| 2024 | Wholesale Access Mandated | No major entrants |
| 2025 | Covenant Bans | 12 sites freed |
| 2026 | Fast-Track Consents | 5 applications pending |

Economic Ramifications
Grocery inflation drags GDP growth to 1.8 percent; manufacturing shrinks 2 percent yearly. Tourism suffers: visitors balk at cafe prices.
Productivity stalls sans competition; FDI shuns retail. Budget pressures mount—10 billion dollars annual consumer loss.

Potential Solutions Debated
- Divestitures: Cap 25 percent regional share, auction stores.
- Public Chain: Crown entity under Commerce Commission.
- Wholesale Separation: Mandatory access at cost-plus.
- Price Caps: Temporary on staples like bread, milk.
Grattan-style: third player via subsidies. Risks: short-term hikes, quality dips.
| Solution | Pros | Cons | Timeline |
|---|---|---|---|
| Divestitures | True competition | Legal battles | 2-3 years |
| Public Grocery | Consumer focus | Taxpayer risk | 5 years |
| Wholesale Access | Low disruption | Enforcement weak | 1 year |
| Price Caps | Immediate relief | Supply distortions | 6 months |
Industry Defenses
Foodstuffs: “Invest 1 billion dollars yearly in supply chains; prices reflect costs.” Woolworths: “Global inflation, weather hits imports.”
Yet margins double pre-2022; executive pay soars 20 percent.
