Ziwi Peak stands apart in the premium dog food market with its distinctive approach to canine nutrition. Drawing inspiration from the ancestral diets of wild canines, this New Zealand-based company has garnered attention for its high-meat formulations and innovative processing techniques. While many conventional dog foods rely on fillers and artificial preservatives, Ziwi Peak emphasizes whole-prey nutrition and minimal processing to deliver nutrient-dense meals that closely mirror what dogs would naturally consume.
The Ziwi Peak philosophy
Founded in 2002, Ziwi Peak has built its reputation on ethical sourcing practices and nutritional integrity. The company exclusively uses free-range, grass-fed meats and sustainably harvested seafood from New Zealand’s pristine landscapes. This commitment extends beyond marketing claims – their supply chain adheres to New Zealand’s rigorous animal welfare standards, ensuring that ingredients meet exceptional quality benchmarks.
The brand’s cornerstone principle is the whole-prey concept, incorporating meat, organs, bone and seafood in proportions that reflect the natural prey animals dogs would consume in the wild. This approach provides a complete nutritional profile without relying on synthetic supplements or fillers commonly found in conventional kibble.
Innovative processing methods
What truly sets Ziwi Peak apart is its unique processing technology. The brand pioneered the use of air-drying for commercial dog food, developing their proprietary Z-TWINTECH system that preserves nutrient integrity while eliminating pathogens. This gentle process slowly removes moisture at low temperatures, locking in vital nutrients and natural flavours without the need for artificial preservatives.
In 2024, Ziwi Peak introduced their Z-MicroSteam technology, particularly relevant for UK customers. This hybrid method pre-steams ingredients to enhance digestibility before air-drying, creating products that maintain nutritional density while catering to dogs with sensitive digestion. The Steam & Dried range now available in the UK market represents this evolution in their manufacturing approach.
Nutritional breakdown
Analyzing Ziwi Peak recipes reveals impressive nutritional metrics that surpass most conventional options. Their formulas typically contain:
- 44-45% protein (dry matter basis)
- 33-35% fat
- Only 13-15% carbohydrates
This macronutrient distribution closely aligns with what nutritionists consider biologically appropriate for canines. The high protein content derives primarily from named meat sources rather than vegetable proteins or by-products, supporting muscle maintenance and overall vitality.
The minimal carbohydrate content addresses concerns about excessive starch consumption in modern dog diets. By avoiding grains, potatoes and legumes, Ziwi Peak reduces the glycemic impact while potentially decreasing risks associated with dilated cardiomyopathy (DCM) that some studies have linked to certain grain-free formulations using legume concentrates.
Ingredient quality and sourcing
Examining Ziwi Peak’s ingredient lists reveals exceptional transparency. Each protein source is clearly identified, with recipes featuring specific meat types like New Zealand grass-fed beef or free-range lamb. The inclusion of 10-30% organ meats (liver, kidney, lung and heart) provides concentrated nutrients often missing from conventional diets.
A signature ingredient across their range is New Zealand Green-Lipped Mussel, a natural source of glucosamine, chondroitin and omega-3 fatty acids that support joint health and mobility. This functional ingredient exemplifies their commitment to incorporating bioavailable nutrients from whole food sources rather than synthetic supplements.
The brand’s strict sourcing protocols exclude Chinese ingredients, addressing common consumer concerns about contamination risks. Their manufacturing facility in Awatoto operates under stringent quality control measures, including HACCP protocols and regular testing by New Zealand’s Ministry of Primary Industries.

Product range and availability
Ziwi Peak offers six core protein options in the UK market: Lamb, Beef, Venison, Free-Range Chicken, Mackerel & Lamb and Tripe & Lamb. Each recipe maintains consistent nutritional principles while providing variety to accommodate protein rotation or address specific protein sensitivities.
The brand’s products come in various formats, with the Steam & Dried range being the primary offering for UK consumers following regulatory adjustments. These products retail between £17-£23 per kilogram, positioning them in the ultra-premium segment.
Despite the higher upfront cost, the exceptional nutrient density means feeding portions are typically 30-50% smaller than conventional kibble. This efficiency partially offsets the price difference, especially for small to medium breeds. However, feeding large dogs exclusively on Ziwi Peak can represent a significant investment.
Safety record and quality assurance
Ziwi Peak maintains an impeccable safety history with zero product recalls since its founding in 2002. This record stems from their vertically integrated supply chain, rigorous testing protocols and limited outsourcing of ingredients.
Each production batch undergoes multiple quality checks, including testing for pathogens, heavy metals and nutritional composition. The brand’s partnership with Massey University for palatability and digestibility studies further demonstrates their commitment to evidence-based formulation.
While isolated reports of adverse reactions exist, comprehensive analysis suggests these represent individual sensitivities rather than systemic quality issues. The brand’s transparency regarding ingredient sourcing and processing methods provides additional confidence for concerned pet owners.
UK consumer experience
British dog owners frequently report exceptional palatability with Ziwi Peak products, even among typically finicky eaters. The intense meaty aroma and taste appeal naturally to canine preferences, often making mealtime eagerly anticipated.
Digestive benefits frequently mentioned in consumer feedback include firmer stools, reduced stool volume and improved digestion. The 95% metabolizable energy rating means most nutrients are absorbed rather than passed as waste, contributing to these positive outcomes.
The transition to Steam & Dried formulations in the UK market has received mixed but generally positive reviews. Some owners noted differences in texture and digestibility compared to the original air-dried versions, but most reported successful transitions with gradual introduction.
What kind of dogs is this food suitable for?
Ziwi Peak formulates their recipes for all life stages, making them appropriate for puppies through seniors according to AAFCO guidelines. However, certain characteristics make them particularly beneficial for specific dogs:
For puppies and young dogs, the high protein content and balanced calcium-phosphorus ratio support proper growth and development without excessive calories that might accelerate growth too rapidly. The inclusion of DHA from seafood ingredients benefits cognitive development in young canines.
For active adult dogs, the nutrient-dense formulation provides sustained energy through appropriate protein and fat levels. Working dogs, sport competitors and highly active breeds can maintain muscle mass and recovery with fewer digestive issues than high-carbohydrate alternatives.
For senior dogs, the inclusion of natural joint-supporting compounds from green-lipped mussels offers particular advantages. The high digestibility reduces strain on aging digestive systems, while the quality protein helps maintain muscle mass often lost during aging.
Dogs with food sensitivities may benefit from Ziwi Peak’s limited ingredient approach and novel proteins like venison or mackerel. The absence of common allergens such as chicken (in specific recipes), corn, wheat, soy and dairy makes identification of trigger foods straightforward.
However, Ziwi Peak may not be ideal for all dogs. The relatively high fat content could be excessive for sedentary or obesity-prone canines. Additionally, the caloric density requires careful portion control to prevent weight gain in less active individuals.
Is this dog food good? A specialist’s conclusion
As a dog food specialist evaluating Ziwi Peak objectively, I would rate it among the top tier of commercial dog foods available in the UK market. The brand exemplifies what nutritionally optimized canine diets should prioritize: high-quality animal proteins, appropriate fat levels, minimal carbohydrates and ingredient transparency.
The company’s commitment to ethically sourced, whole-food ingredients addresses both nutritional needs and ethical concerns many modern pet owners hold. Their processing methods preserve nutritional integrity while ensuring food safety, representing a significant advancement over conventional kibble manufacturing.
That said, no dog food is perfect for every situation. The premium pricing makes Ziwi Peak prohibitive for many pet owners, particularly those with larger breeds. While the feeding efficiency partially offsets costs, the financial reality remains a legitimate consideration.
Additionally, the high protein and fat content may not suit every dog’s metabolic needs. Less active dogs might experience weight gain without careful portion control, and some individuals with specific health conditions might require different nutritional profiles.
Nevertheless, for pet owners prioritizing biological appropriateness, ingredient quality and manufacturing integrity, Ziwi Peak represents an excellent choice that closely approximates the nutritional profile dogs evolved to consume. I consider it a benchmark against which other premium dog foods should be measured.
