The New Zealand grocery market is highly concentrated: Woolworths NZ and Foodstuffs held 82% of the retail grocery market in 2025, down only slightly from 84% in 2020 (Commerce Commission, Annual Grocery Report, June 2026), which limits competition. Aldi does not operate in New Zealand; the main newer entrant is Costco, with one Auckland warehouse and a second announced for Drury. Budgeting accurately for groceries is an important part of any NZ financial plan.
Budget $300–$400/month for a single person, $600–$800/month for a couple, and $900–$1,200/month for a family of four — shopping at mid-range supermarkets. Pak'nSave is positioned as the lowest-priced format, below New World and Woolworths. Buying in-season produce, using Pak'nSave's no-frills format, and reducing meat consumption are the three most impactful ways to reduce grocery spend.
Average Grocery Budget by Household Size
These figures are for typical supermarket shopping in 2026. They include all food and non-alcoholic beverages; alcohol, cleaning products, and personal care items are separate.

Key Cost Drivers in NZ Groceries
1. Market Concentration
The Grocery Commissioner (established under the Grocery Industry Competition Act 2023, following the Commerce Commission’s market study) monitors the sector and oversees wholesale access for competitors, but the Commission’s June 2026 report found little change in core competition measures. Costco’s growth in Auckland is the most visible new competition.
2. Fresh Produce Seasonality
NZ produce prices are highly seasonal. Tomatoes averaged $3.87/kg in February 2025 and $16.17/kg in August 2025 (Stats NZ). Across 2025, the cheapest month for broccoli, cabbage and lettuce was 44–61% below the dearest.
In-Season Produce Calendar (NZ)
| Season | Cheap items |
|---|---|
| Summer (Dec–Feb) | Tomatoes, capsicum, courgette, stone fruit, berries, sweetcorn |
| Autumn (Mar–May) | Apples, pears, pumpkin, kumara, leeks |
| Winter (Jun–Aug) | Silver beet, cabbage, root vegetables, kiwifruit |
| Spring (Sep–Nov) | Asparagus, peas, new potatoes, new-season apples |
Strategies to Reduce Your Grocery Bill
High Impact
- Shop at Pak’nSave for bulk staples: rice, pasta, canned goods, dairy, meat.
- Cut back on meat: beef mince averaged $24.11/kg and chicken breast $15.50/kg in June 2026 (Stats NZ average prices above), so a few meat-free dinners a week make a noticeable difference.
- Buy in-season produce: the gap between the cheapest and dearest month was 44–76% for tomatoes, broccoli, cabbage and lettuce in 2025.
- Meal plan for the week so you buy only what you will use and avoid impulse buys.
- Buy generic/homebrand where quality is equivalent — pasta, rice, tinned tomatoes, flour, oats, oil, canned beans.
Medium Impact
- Check the Woolworths and New World apps for the week’s specials before you shop.
- Shop weekly, not daily — daily shoppers spend significantly more due to impulse purchases.
- Costco membership (annual fee): breaks even quickly for families buying large quantities of meat, dairy, and household products.
- Grow your own herbs and salad greens: packaged fresh herbs averaged $5.16 in June 2026 (Stats NZ); a pot costs a few dollars and produces for months.
- Bulk cooking and freezing — cook large batches of mince, soups, and casseroles; freeze in portions.
Lower Impact
- Loyalty schemes (Woolworths Everyday Rewards, which replaced Onecard in February 2024; Foodstuffs’ Club+, which replaced New World Clubcard and works at New World, Pak’nSave and Four Square): modest discounts on specific items
- Bread-making: fresh bread costs about $0.80/loaf in ingredients vs $2.33–$4.60 for a sliced loaf in store (Stats NZ average prices, June 2026)
