ZIWI Peak vs ACANA dog food — an honest NZ comparison of ingredients, processing, and daily cost. Which premium brand suits your dog's needs and budget best?
Last updated
By Jess Aldridge 
ZIWI Peak and ACANA are the two most discussed premium dog foods in NZ — one from Mount Maunganui, one from Canada. They both take quality seriously. They are not the same product and they don’t cost the same.
ZIWI Peak is the better food by most objective measures. Higher meat inclusion, minimal processing, whole-prey nutrition, NZ-sourced ingredients. If you want to feed your dog the best commercial food available in this country and can stomach the price, ZIWI is it.
ACANA is the smarter buy for most households. It costs roughly one-third as much per day, still uses genuine fresh and raw meat as its first five ingredients, and for the vast majority of healthy dogs the real-world outcome is excellent. Stepping up from Black Hawk or Ivory Coat to ACANA is a meaningful quality jump. Stepping up from ACANA to ZIWI is a real improvement too — just not a three-times-the-price improvement for most dogs.
The clear call: Feed your dog ACANA as their daily food. Add ZIWI as a topper if the budget allows. That combination gets you close to pure ZIWI nutrition at about half the cost.
| ZIWI Peak | ACANA | |
|---|---|---|
| Origin | Mount Maunganui, NZ | Alberta, Canada |
| Format | Air-dried | Kibble (extruded) |
| Meat inclusion | ~96% | ~60–70% |
| Protein (as-fed) | 36–45% | 29–35% |
| Fat (as-fed) | 25–33% | 15–17% |
| NZ availability | Very wide | Wide |
| Price per kg | $30–35 | $8–10 |
| Daily cost (20kg dog) | $9–12 | $2.40–3.00 |
| Key proteins | Beef, lamb, venison, mackerel, chicken | Chicken, turkey, lamb, duck, fish |
| Grain/legume-free | Yes | Grain-free (contains legumes) |
| NZ-made | Yes | No (Canadian) |
| PawPick rating | 9/10 | 8/10 |
Both brands lead with real meat and are transparent about what they put in the bag. That’s where much of the similarity ends.
The ZIWI Peak Beef recipe lists: beef, beef heart, beef kidney, beef tripe, beef liver, beef lung, New Zealand green-lipped mussel, beef bone, lecithin, inulin (from chicory), dried kelp, minerals, vitamins.
What stands out:
The ACANA Heritage Original recipe leads with: fresh chicken meat, fresh turkey meat, fresh chicken giblets, fresh whole eggs, fresh whole flounder — then continues into chicken meal, turkey meal, lentils, chickpeas, green peas, and supporting ingredients.
What stands out:
ZIWI wins on ingredient quality by a clear margin. Virtually no plant content, more complete whole-prey inclusion, less processing. For dogs with allergies or sensitivities, the difference is more than academic — ZIWI’s limited-ingredient recipes genuinely work where others fail.
For a healthy adult dog, ACANA’s actual daily nutritional outcome is excellent. The fresh meat sourcing and high protein content produce real results. The gap between ZIWI and ACANA is real; whether it justifies the price difference depends on your dog’s specific needs.
| ZIWI Peak (Beef Air-Dried) | ACANA (Heritage Original) | |
|---|---|---|
| Protein | 36% min | 29% min |
| Fat | 33% min | 17% min |
| Fibre | 2% max | 5% max |
| Moisture | 14% max | 12% max |
| Protein (dry matter) | ~42% | ~33% |
| Fat (dry matter) | ~38% | ~19% |
| Calories | ~4,400 kcal/kg | ~3,510 kcal/kg |
A few things worth noting:
ZIWI is much more calorie-dense. A 20kg dog eats roughly 145–190g of ZIWI per day versus 280–320g of ACANA Heritage. That changes the maths on how far each bag actually goes — a 4kg ZIWI bag lasts around 3–4 weeks for a medium dog. A 6kg ACANA bag lasts roughly 3 weeks for the same dog.
The fat gap is significant. ZIWI’s 33% fat is appropriate for active dogs but can cause weight gain in couch-dwellers. ACANA’s 17% fat is much easier to manage for less active or overweight dogs.
Both are high-protein by market standards. ACANA’s 29% sits well above mid-range brands like Black Hawk (24%) or Purina Pro Plan (28%). ZIWI’s 36–45% range is at the top end of the commercial market.
This is the conversation-ender for most households.
| Scenario | ZIWI Peak | ACANA Heritage | Difference |
|---|---|---|---|
| 10kg dog, daily feeding | $4.50–6.00 | $1.20–1.60 | ~$3–4/day |
| 20kg dog, daily feeding | $9.00–12.00 | $2.40–3.00 | ~$6–9/day |
| 30kg dog, daily feeding | $14.00–18.00 | $3.50–4.50 | ~$10–14/day |
| 20kg dog, annual cost | $3,285–$4,380 | $876–$1,095 | ~$2,400–$3,300/year |
Estimates based on 2026 NZ retail pricing across Animates, Petstock, and PetDirect. Actual costs vary by recipe, bag size, and retailer.
The annual gap for a medium 20kg dog — roughly $2,400–$3,300 — is significant for most NZ households. That’s not a small rounding difference.
The topper strategy: Many owners land on feeding ACANA as the daily base and adding 1–2 tablespoons of ZIWI air-dried per meal. Daily cost for a 20kg dog on this approach runs roughly $3.50–5.00 — meaningfully better than full ZIWI, still better nutritionally than ACANA alone.

This is a meaningful practical difference.
ZIWI Peak: Ready to serve straight from the bag. No prep, no water, no mixing required. Some owners add warm water to release more aroma, but it’s optional. Storage is simple — sealed bag in a cool dry place, use within 8 weeks of opening. The air-dried format is genuinely convenient despite being a premium product.
ACANA: Kibble — scoop from bag, done. The format is straightforward and familiar. Requires a longer transition period (10–14 days) due to the richness of the formula. Storage is the same as any dry kibble. No rehydration needed.
Which is more convenient? They’re about equal day-to-day. ACANA is slightly more forgiving in transition (less rich than ZIWI’s freeze-dried boosters) and the kibble format is familiar to most dogs. ZIWI has an edge for picky eaters — the air-dried meat scent is stronger and dogs often take to it immediately.
Neither requires the prep work of K9 Natural (which should be rehydrated), which makes both easier than NZ’s other premium brand.
ZIWI’s range is protein-focused with minimal variation in format — each recipe is essentially a whole-prey formulation around a single or paired protein. The East Cape recipe is the dedicated limited-ingredient option for elimination diets.
ZIWI also makes a canned wet food range (same core proteins) and freeze-dried raw boosters. The wet food is a solid mixer for dogs who prefer a wetter texture.
Heritage Collection (most accessible):
Regionals Collection (higher protein):
Singles Collection (limited ingredient):
ACANA has more variety within its range, including dedicated senior and puppy formulas, and the Singles range for dogs needing a limited-ingredient diet. The Singles range is the weak link — availability in NZ is patchy and you may need to special order.
ZIWI Peak is widely available across NZ. It’s on the shelf at Animates, Petstock, Raw Essentials (17 stores), PetDirect, Pet Circle, and most independent pet stores. Being a NZ brand helps — the distribution network is well-established. All core recipes are easy to find. The East Cape limited-ingredient recipe is the one you might need to hunt for online.
ACANA is available at Animates, Petstock, PetDirect, and most independent stores that stock premium brands. Heritage and Regionals varieties are reliably in stock. The Singles range (limited ingredient) is harder to find — most stores either don’t stock it or carry limited variety, so plan for online ordering if your dog needs single-protein feeding.
For NZ owners outside main centres, ZIWI is more reliably available on local shelves. Both brands are easy to access online with NZ delivery.
If you’re moving to either brand from a mid-range kibble, transition gradually to avoid digestive upset.
To ACANA: 7–10 day transition. ACANA’s richness is the main challenge — the higher protein and fat levels can cause loose stools if introduced too quickly. Start with Heritage before moving to Regionals if your dog has a sensitive stomach.
To ZIWI Peak: 7–14 day transition. The switch from kibble to air-dried changes both texture and macronutrient ratios. Some dogs handle it easily; others need more time. Adding warm water during transition can help palatability.
Between ACANA and ZIWI: There’s no medical issue with switching between them or using them together. The most common approach is feeding ACANA as the base and adding ZIWI as a topper — in that case, a formal transition isn’t necessary.
Online reviews across NZ pet forums and the PetDirect review section tell a fairly consistent story for both brands.
ZIWI Peak owners are nearly universally positive. The most common observations: dramatic improvement in coat shine within weeks, improved stool quality (smaller, firmer), and dogs that were previously picky eaters cleaning the bowl every time. The most common complaints are cost and the strong smell during handling (dogs love it; humans less so). Owners with allergy dogs are particularly loyal — many report that ZIWI solved problems that nothing else had.
ACANA owners report similar positives — good coat condition, settled digestion once transitioned, strong palatability. The Regionals range in particular gets consistently strong feedback. The complaints that come up are: the transition difficulty (loose stools in the first week or two are common), the richness being too much for some sensitive dogs, and the legume content for owners who’ve gone down the DCM research rabbit hole. The price also comes up, but mostly in comparison to mid-range brands rather than ZIWI.
The practical verdict from NZ owners: both are genuinely good foods. For dogs where ACANA is working well, there’s rarely a compelling reason to switch to ZIWI. For dogs where nothing else has worked, ZIWI’s simpler formulation often solves the problem.
Both brands are excellent. Neither will let your dog down. The decision usually comes down to three things: your dog’s specific needs, their size, and your budget.
Best value: ACANA. Strong ingredients, real outcomes, a daily cost that doesn’t require a rethink of household finances. The right choice for most NZ households.
Best for allergy dogs: ZIWI Peak. The whole-prey, legume-free formulation and single-protein options are the best elimination diet tool available in NZ retail.
Best overall strategy: Feed ACANA daily, add ZIWI as a topper. You get the nutritional lift of ZIWI without the full-time price tag, and your dog gets variety that keeps mealtimes interesting.
If you’re deciding today and your dog is healthy with no known sensitivities — start with ACANA Heritage. If budget allows after a few months and you want to take it further, add ZIWI.
Both are genuinely premium options. ZIWI Peak has higher meat inclusion and undergoes less processing, making it the better food on paper. ACANA delivers very strong nutrition at roughly one-third the daily cost, making it the smarter choice for most NZ households — especially those feeding medium to large dogs.
For a 20kg dog, ZIWI Peak costs approximately $9–12 per day. ACANA costs approximately $2.40–3.00 per day on the Heritage range. ACANA is around 75% cheaper per day, though it uses a different manufacturing process (kibble extrusion vs air-drying).
ACANA is excellent kibble — among the best in the NZ market — but ZIWI Peak has higher meat inclusion (96% vs around 60–70%), less processing, and a more complete whole-prey nutritional profile. For most healthy adult dogs, ACANA provides very good outcomes at a fraction of the cost. ZIWI is the better food, but whether that gap justifies the price difference depends on your dog and your budget.
ZIWI Peak has a slight edge for allergy dogs. Its limited-ingredient recipes (East Cape, single-protein options) are excellent for elimination diets, and the whole-prey formulation avoids the legumes and plant proteins that can cause issues in sensitive dogs. ACANA's Singles range also works for allergies but can be hard to find in NZ stores.
Mostly. Both are stocked at Animates, Petstock, and PetDirect. ZIWI Peak has slightly wider availability — it's in more independent pet stores and Raw Essentials outlets. ACANA's full range (particularly Singles) can be harder to find outside major cities.
ACANA is the more practical choice for large dogs. Feeding ZIWI Peak as a sole diet to a 30kg dog costs $14–18/day, which is simply not sustainable for most households. ACANA delivers premium nutrition at $3–4/day for the same dog. ZIWI works well as a topper over ACANA for large breeds.
Yes. Using ZIWI as a topper over ACANA kibble is a popular and effective strategy — you get the premium nutrients and palatability of ZIWI without paying for a full air-dried diet. A tablespoon of ZIWI over a bowl of ACANA Heritage delivers strong nutrition at a manageable daily cost.
