The short answer: New Zealand Wagyu is Wagyu raised in New Zealand, a small herd built mostly from crossbreds, often Wagyu bulls over dairy cows. Much of it is raised on pasture rather than finished on grain. It's leaner and beefier than Japanese Wagyu, which is 100% Japan's native breeds, fattened on a grain-based diet from about 11 to 30 months.
What is New Zealand Wagyu?
New Zealand Wagyu is Wagyu raised in New Zealand. The first New Zealand-born Wagyu calf came from an embryo transfer in 1991 [1], and the country's breeders' association keeps a herd register with DNA parentage checks [2]. Like every Wagyu herd outside Japan, it descends from an estimated 221 cattle that left Japan between 1976 and 1997 [5].
Most New Zealand Wagyu beef is crossbred. The best-known program, backed by government funding from 2012, breeds Wagyu bulls over dairy cows, with some Angus crosses as well [3][4].
How is New Zealand Wagyu raised?
Often on grass. New Zealand's beef industry is built on pasture, and its largest Wagyu program sells its beef as grass-fed [3][4]. That's the opposite of Japan, where Japanese Black cattle are fattened in barns on a high-concentrate, grain-based diet from about 11 to 30 months of age [6].
How does New Zealand Wagyu compare with Japanese Wagyu?
They're different products for different tables. A grass-fed Wagyu cross is a lean, beefy steak with more marbling than ordinary grass-fed beef. Japanese Black loin averages over 30% intramuscular fat [6], in fine flecks through the whole muscle.
| New Zealand Wagyu | Japanese Wagyu | |
|---|---|---|
| Genetics | Mostly crossbred, often Wagyu over dairy cows [3][4] | 100% Japan's native breeds, mostly Japanese Black |
| Gene pool | About 221 animals exported 1976–1997 [5] | Japan's full breeding population |
| Feed | Often pasture [3] | Grain-based fattening diet with hay or rice straw [6] |
| Marbling | Moderate | Over 30% loin fat on average [6] |
| ID | Breed register for registered animals [2] | 10-digit national ID for every animal |

How does Peak Wagyu compare?
Peak Wagyu is Japanese Fullblood: Japanese Black, born, raised, graded and processed in Japan. Our farm, Takeda Farm in Hokkaido, feeds a ration that's about half Hokkaido-grown hay, along with oats and rice bran from Asahikawa mochi barley, and ships each cow before maximum weight.
The current cow, Takemitsu-chan, graded A4, BMS 6, above the ceiling of USDA Prime and more balanced than a top-marbled A5. Her ID, 1493019197, and her grading certificate are on her page.
Frequently asked questions
Is New Zealand Wagyu grass-fed?
Much of it is. New Zealand's best-known Wagyu program raises Wagyu crossbreds on pasture. Japanese Wagyu is fattened in barns on a grain-based diet for well over a year, which is a large part of why it marbles so heavily.
Is New Zealand Wagyu fullblood?
Mostly not. New Zealand has a small Wagyu breeders' association that registers fullbloods, but most New Zealand Wagyu beef comes from crossbreds, often Wagyu bulls bred to dairy cows.
How does New Zealand Wagyu compare with Japanese Wagyu?
It's a different product. Crossbred, pasture-raised Wagyu has more marbling than ordinary grass-fed beef but far less than Japanese Black, which averages over 30% intramuscular fat in the loin.
