About the Federation
The Commercial Mushroom Growers Federation of New Zealand, known as Kiwi Mushrooms, is the industry body that brings the country's commercial mushroom growers together.
Who we are
We represent New Zealand mushroom growers, from family farms that have been composting and picking for decades to specialist growers of exotic varieties.
Mushroom farming is a highly specialised kind of horticulture. It happens indoors, all year, with its own composting science, growing rooms and harvesting skills. Farms in New Zealand range from about 5 tonnes a week to well over 100 tonnes, and the Federation gives growers of every size a place to come together.

What we do
A network for New Zealand's commercial mushroom farms to share experience, compare notes and tackle common challenges.
From compost and pasteurisation to harvesting and packing, we explain how mushrooms are grown, for growers, students and the curious.
Recipes, nutrition information and partnerships that inspire Kiwis to cook with mushrooms, including our Kiwi Mushrooms recipes on Beef + Lamb New Zealand's recipes.co.nz.
Our members
Three commercial farms grow the mushrooms you see in Kiwi kitchens, from certified organic buttons in the Waikato to Auckland exotics and the Bombay Button.
Ohaupo, Waikato
A family-owned farm in Ohaupo, in the heart of the Waikato, Quality Mushrooms grows the only certified organic mushrooms in New Zealand. Mushrooms are grown indoors all year in nine sheds, and the farm produces 10–12 tonnes a week.
South Auckland
Out of the Dark Mushrooms, also known as Exotics by South, is Auckland's exotic mushroom specialist, growing shiitake, oyster and enoki. According to its website, the farm grows about a tonne of mushrooms a week, with around 60% going to leading restaurants.
Pukekawa, Waikato
Home of the Bombay Button, Mercer Mushrooms is a modern farm on the southern slopes of the Bombay Hills in Pukekawa, beside the Waikato River. It grows white button, Swiss brown and portobello mushrooms, and can produce 60 tonnes a week.
