Truffles are a recognised product group under the Horticulture Export Authority Act 1987.  Southern Truffles NZ Ltd (STNZL), as the Recognised Product Group for Truffles, is responsible for developing and maintaining the Export Marketing Strategy (EMS) for truffles and collecting any levies required by the EMS.  

In accordance with the EMS, anyone wishing to export truffles from NZ must be a member of NZTA and obtain a licence or exemption from HEA, whose website can be found at HEA. The HEA website also contains the forms and requirements for exporting products that have opted to utilise the opportunities the HEA act provides.
