Mushroom House is a mushroom grower at 1 Northpoint Street in Plimmerton, Porirua. The business grows oyster mushrooms every week and sells them to the public and to wholesalers. It describes its mushrooms as plentiful and tasty, and it makes mushroom products, including crispy mushroom chips inspired by a snack the founder tried in the Philippines.
The business was started by Rochelle and her husband, who began growing mushrooms in their own bathroom and later moved to a commercial space in Plimmerton, where they both grow mushrooms and make products. The website says the business aims to make mushrooms a bigger part of New Zealand food. Its growing and production happen at the one site.
