New Zealand grocery prices are among the highest in the OECD relative to incomes — a consequence of the long-standing supermarket duopoly (Foodstuffs and Woolworths NZ). The Commerce Commission’s 2022 inquiry found NZ grocery prices are 10–20% higher than comparable markets. This guide gives benchmark spending figures and practical strategies to reduce your grocery bill.
The average NZ household spends $220–$310/week on groceries and takeaways combined. Groceries alone (supermarket only) average $150–$230/week for a family of four. Shopping at PAK'nSAVE instead of Countdown or New World saves most families $15–$30/week on a typical shop.
Average Weekly Grocery Spend by Household Size (2026)
These figures are for supermarket food and household basics only (not including takeaways, cafes, or restaurants):
| Household | Budget weekly spend | Average weekly spend | Generous weekly spend |
|---|---|---|---|
| Single person | $70 – $90 | $100 – $130 | $150 – $190 |
| Couple, no children | $110 – $140 | $155 – $200 | $230 – $290 |
| Family of 3 (1 child) | $140 – $175 | $195 – $250 | $290 – $360 |
| Family of 4 (2 children) | $170 – $210 | $230 – $310 | $360 – $440 |
| Family of 5 (3 children) | $205 – $255 | $280 – $370 | $430 – $530 |
| Flatmates (per person) | $60 – $80 | $90 – $120 | $130 – $160 |
Adding Takeaways and Eating Out
Most NZ household surveys include all food expenditure — groceries plus eating out. Stats NZ data suggests:
| Household | Avg. monthly spend on takeaways / dining out |
|---|---|
| Single, no children | $150 – $350 |
| Couple, no children | $250 – $550 |
| Family of 4 | $200 – $400 |
Even modest takeaway habits add $100–$300/month to food costs. A $20 lunch four days a week equals $400/month — often more than a week’s grocery budget.
Supermarket Price Comparison — NZ 2026
NZ has three main supermarket chains with significantly different price points:
| Supermarket | Typical price index | Notes |
|---|---|---|
| PAK’nSAVE | 100 (cheapest) | Limited-service format; generally 10–15% cheaper |
| Countdown (Woolworths NZ) | 110 – 115 | Wider product range; often more convenient |
| New World (Foodstuffs) | 112 – 118 | Similar to Countdown; regional pricing varies |
| Costco (Auckland, Silverdale) | 85 – 95 | Bulk buying required; membership $70/year |
| Farro Fresh | 130 – 150 | Specialty/premium products |
Costco caveat: Costco is excellent value for bulk staples (nuts, cooking oil, cleaning products, toiletries). It’s not suitable as a weekly grocery shop without freezer/pantry space for bulk quantities.

How to Reduce Your Grocery Bill
1. Switch to PAK’nSAVE for staples
PAK’nSAVE’s lower-service model is consistently 10–15% cheaper than Countdown or New World on comparable products. A family spending $260/week at Countdown could save $26–$40/week by switching — over $1,500/year.
2. Buy store/home brands
Countdown Essentials, PAK’nSAVE Value, and New World Budget brands are typically 20–40% cheaper than branded equivalents. For staples like pasta, rice, canned goods, cleaning products, and toiletries, quality differences are minimal.
3. Plan meals and shop with a list
Unplanned shopping increases spending by an estimated 20–40%. Meal planning for the week and shopping with a list reduces impulse buying and food waste (the average NZ household throws away $1,000–$2,000 of food per year).
4. Reduce food waste
NZ households waste approximately 3 meals’ worth of food per week on average. Key strategies:
- First in, first out in the fridge
- Freeze meat, bread, and leftovers before they go off
- Plan meals around what’s already in the fridge
5. Use loyalty programmes wisely
- Everyday Rewards (Countdown): Earns you grocery discounts on spending milestones
- New World Clubcard / Foodstuffs: Regional loyalty benefits
- Collect Airpoints: Some credit cards earn Air NZ Airpoints Dollars on supermarket spending — see best Airpoints credit cards NZ
6. Shop seasonally
NZ seasonal produce is dramatically cheaper than out-of-season imported produce. Winter: kumara, carrots, cabbage, onions, pumpkin. Summer: zucchini, capsicum, tomatoes, stone fruit. Buying seasonal whole vegetables and cooking from scratch cuts costs by 30–50% versus convenience or processed foods.
