We ship all items as soon as possible via NZ Post. When items are in stock, they will normally be shipped on the next business day, unless there is a reason not to, for example live cultures shipped just before a long weekend when freight might be delayed, in which case it will be sent at the earliest appropriate time. Because we deal with a wide range of living mushroom cultures, some products may be delayed in dispatch for a few days if we are waiting on a fresh batch of product to be ready. We prefer to send products in a fresh and high quality condition rather than keeping large volumes of stock on hand at all times. This is in the interest of providing you, our customer, with the best possible quality of product. You will receive an email to notify you when your order has been dispatched, which will include its NZ Post tracking number. Please contact us if you have any questions about your parcel or if it does not arrive.
