The Complete Keto Grocery Shopping List NZ (2026): What to Buy, What to Skip, and Weekly Cost
A keto grocery list built for New Zealand shoppers centres on three things: low-carb vegetables, quality protein and fat, and cutting out anything with added sugar or refined starch. For one adult, a realistic weekly grocery spend sits somewhere between $115 and $135, depending on how much fish and premium cuts you buy versus chicken, eggs and mince.
That's the short answer. Here's the full breakdown.
What "Keto-Friendly" Actually Means at the Checkout
Keto isn't complicated at a nutrition level — under roughly 20–50g of carbs a day, moderate protein, high fat. Where people trip up is at the supermarket, where half the aisles are built around bread, cereal, pasta and sugar. Shopping keto in New Zealand mostly comes down to sticking to the perimeter of the store: fresh produce, meat, fish, dairy and eggs — and reading labels carefully on anything packaged.
The NZ Keto Shopping List by Category
| Category | Buy | Skip or Limit |
|---|---|---|
| Vegetables | Broccoli, cauliflower, spinach, lettuce, courgette, capsicum, mushrooms, cucumber, celery, leafy greens | Potato, kumara, corn, most squash and pumpkin (small amounts of pumpkin are fine in moderation) |
| Fruit | Avocado, berries (strawberries, raspberries) in small portions | Bananas, apples, oranges, mango, grapes — all high in natural sugar |
| Protein | Chicken thighs, beef, lamb, pork, eggs, salmon, tuna, snapper | Crumbed or battered meat and fish, sweet glazes and marinades |
| Dairy & fats | Butter, olive oil, full-fat cream, hard cheese, full-fat Greek yoghurt | Low-fat "diet" dairy — it's usually higher in sugar to compensate for the fat removed |
| Pantry | Nuts, seeds, olive oil, mayonnaise (check sugar content), stock, herbs and spices | Bread, pasta, rice, flour, most sauces and condiments (check labels — sugar hides in ketchup, BBQ sauce, and Asian-style sauces) |
| Snacks | Nuts, cheese, boiled eggs, keto-friendly crackers | Muesli bars, chips, lollies, most "protein" bars (many are carb-heavy) |
| Drinks | Water, black coffee, tea | Soft drink, juice, most alcohol (beer especially) |
The pattern: if it grew in the ground above the soil, or it walked, swam or laid an egg, it's almost always fine. If it came out of a packet with a long ingredients list, check it.

Add pantry basics — butter, olive oil, hard cheese, nuts — and a solo keto week typically lands around $115–$135, depending on which cheese and how much fish you're buying. Fish and premium cuts are the two levers that move this number most; leaning on chicken thighs, mince and eggs keeps it toward the lower end.
Family of two on keto: roughly $180–$220/week, scaling with appetite and how much fish or lamb makes the list versus chicken and pork.

Three Mistakes That Blow Out a Keto Grocery Bill
- Buying "keto" packaged snacks instead of whole food. Keto-branded bars and crackers carry a premium. A block of cheese and a handful of nuts does the same job for less.
- Over-buying fish. Salmon and tuna are excellent keto proteins but the most expensive per kilo on this list. Rotate with chicken thighs and mince to keep the weekly average down.
- Not checking sauces and dressings. Tomato sauce, sweet chilli, teriyaki and most bottled salad dressings are loaded with sugar. Olive oil, vinegar, and mayonnaise (checked for sugar content) are the safe defaults.
Frequently Asked Questions
Is fruit allowed on keto? Most fruit is too high in natural sugar for strict keto. Avocado is the exception — it's high in fat and very low in carbs. Berries (strawberries, raspberries) are the next best option in small portions.
How much does a keto diet cost per week in New Zealand? For one adult, expect roughly $115–$135 a week, built around eggs, chicken, some fish, and low-carb vegetables. The two biggest cost levers are how much fish you buy and which cheese you choose.
Can you get keto groceries delivered in Auckland? Yes. TUM.co.nz delivers a curated keto-friendly range — including fresh produce, meat, fish, eggs and dairy - with free delivery on orders over $70.
What vegetables should I avoid on keto? Potato, kumara, corn, and most winter squash are too high in carbs for strict keto. Leafy greens, broccoli, cauliflower, courgette and capsicum are the safest everyday choices.
Is dairy keto-friendly? Full-fat dairy is fine — butter, cream, hard cheese, and full-fat Greek yoghurt. Low-fat or "lite" dairy products are usually worse for keto, since sugar is often added back in to replace the fat that was removed.
