Our Sustainability Pillars

Hãhã are proud to have been certified 100% sustainable by Sustainable Winegrowing New Zealand since 2011. Sustainable Winegrowing NZ is widely recognised as a world-leading sustainability programme and was one of the first to be established in the international wine industry in 1995. You’ll find some examples of our sustainability practices and initiatives below.



We continually seek ways to actively reduce CO2 emissions, such as:

  • Our bottling and warehousing plant is the first certified carbon-zero bottling company in New Zealand, using 100% renewable energy.
  • We only use lightweight bottles which are manufactured in New Zealand using a high percentage of recycled glass.
  • Our wines are bottled in the North Island, reducing unnecessary shipping of wines and packaging materials.



To minimise and conserve water:

  • Our vineyards use efficient irrigation systems and adopt water-saving practices wherever possible.
  • Barrel washing is done with steam, hot water, and pressure washing to reduce water volume used and limit wash additives going to waste.
  • Wastewater from the wine-making process is cycled through a heat exchange system to cool water for re-use.



Eco-friendly practices are used throughout our winegrowing and winemaking processes, including:

  • Grape marc is either returned to the vineyard as compost or it is used as stock feed.
  • Waste water at the winery is filtered through New Zealand’s first large-scale winery worm farm, which removes Biological Oxygen Demand (BOD) and other contaminants.



In order to minimise the use of herbicides and pesticides in the vineyard, we graze sheep in the vines over winter, which reduces the need for tractor use and returns nutrients to the soil.

Our vineyards also have inter-row plantings to increase the soil diversity, improving soil condition and water retention, which enhances the resilience of our vineyards for the future.



Staying true to the Hãhã name, we consult with local Iwi – Ngãti Kahungunu – to ensure we practice kaitiakitanga – guardianship, protection and preservation of the land.

We are committed to maintaining a supply-chain free from human trafficking and exploitation.

If we take care of the Earth, and take care of the people, we will take care of the future.
