Viticulture & Wine Certification

Organic winegrowers work in harmony with nature. Growers value and encourage biodiversity in the vineyard, and use biological and naturally derived materials to enhance fertility and manage disease. Health is built from the ground up, with biologically active soils nourishing robust vines and fruits. 

Many leading and iconic New Zealand wine brands have demonstrated the advantages of organic management, noting improved wine quality and complexity from healthy organic fruit.

BioGro have been certifying New Zealand Organic Winegrowers for over 25 years. Our dedicated team have specialist knowledge in organic viticulture, winemaking and exporting. 

Certification can take up to 3 years

BioGro certification requires a minimum of 3 years compliance with the BioGro NZ Organic Standards;

  • Year 1 - Registration year (CO)

  • Year 2 - C1 Conversion status

  • Year 3 - C2 Conversion status

  • Year 4 onwards - fully certified organic

Your first audit will determine the registration start date of your property. To move through each stage of conversion to fully certified, you will need to demonstrate compliance with the BioGro NZ Organic Standards through annual renewal applications and audits.

If you believe that you had been following the BioGro Standards before you applied for certification then you can apply for retrospective registration up to a maximum of two years (that is, backdating of the registration start date). If you are looking to export to the EU, Taiwan or Switzerland you can apply for a maximum of 12 months retrospective registration.
