Truffles are a recognised product group under the Horticulture Export Authority Act 1987. Southern Truffles NZ Ltd (STNZL) is tasked with developing an Export Market Strategy (EMS) for truffles. Anyone wishing to export truffles from NZ must obtain a licence or an exemption from STNZL.
The EMS defines the requirements for exporting, including the quality standards. To export, you must be a member of the NZ Truffle Association. The EMS document is available under the Members section.
