NZ wine oversupply after vintage 2026: where the industry stands and what to do now

For three years the conversation in New Zealand wine has been about too much of it. The 2026 vintage, smaller and of very good quality, has eased the pressure, but it hasn’t made the problem go away — and the decisions growers and wineries took to get there have been painful. Here is where things stand in late 2026, using New Zealand Winegrowers’ and Wine Marlborough’s own figures, and what you can do with your records to make the next calls easier.

How the oversupply happened

Wine Marlborough’s 2026 vintage report sets out the chain of events. The light 2021 crop arrived at a time of strong Covid-era demand, so companies leaned into the large 2022 and 2023 vintages. That left the region with an oversupply, high grape prices and, at the same time, a global downturn in wine consumption. A bumper 2025 vintage didn’t help: New Zealand Winegrowers says the crop would have significantly exceeded any previous vintage in the country’s history, and wineries limited their grape intake against an uncertain demand outlook.

Vintage 2026: smaller, and closer to balance

New Zealand Winegrowers’ 2026 Annual Report puts vintage 2026 at approximately 440,000 tonnes, down 15% on the previous year, “bringing production into closer balance with current market demand”. In Marlborough, companies imposed much tighter restrictions on fruit intake in 2026, with plans for a similar approach in 2027. A cool, wet January was followed by a warm late summer and autumn, and Wine Marlborough describes the fruit as excellent across all varieties, with naturally lighter yields.

Vintage 2026: about 440,000 tonnes, down 15% on 2025. Exports to June 2026: $2.108 billion and 306.2 million litres (New Zealand Winegrowers, Annual Report 2026).

The cost has fallen on growers. Wine Marlborough reports lost contracts for some and reduced income for others in the face of rising costs, with the downturn felt by contractors and suppliers across the region. Many growers are pulling out older vines with reduced vigour and either redeveloping or looking at another land use.

Exports: volume up, value flat

Export volumes have held up. In the 12 months to June 2026, exports reached $2.108 billion and 306.2 million litres — the industry’s second-highest June-year total on record, with overall sales up 8%. Around 90% of New Zealand wine is exported, so what happens overseas sets the price of fruit at home.

• United States: still the largest market — $762 million in the year to June 2025, down 3%, according to NZW. Tariffs on New Zealand goods rose in April 2025 and again in August 2025, and the rate has kept moving: in late July 2026 1News reported a 12.5% tariff on most New Zealand exports, up from 10%. Check the rate in force with your importer before you price a shipment.
• Second-tier markets: exports to markets other than the UK, USA and Australia grew 17% to just under $600 million in the year to June 2025, with China up 47% and South Korea up 92%.
• India: the India–New Zealand Free Trade Agreement came into force in October 2026. NZW says tariffs on eligible New Zealand wine will fall over ten years from 150% to 50% or 25%, depending on the wine’s value. Exports there are still small — just under $438,000, up 48% in the last year.

What growers can do now

None of the following changes the market, but each makes the next negotiation or decision rest on facts rather than impressions.

• Know your cost per tonne and per hectare, block by block. When a contract is cut or a winery offers a lower price, you need to know which blocks still pay and which don’t.
• Keep a clean spray diary and harvest record for every block. Buyers taking less fruit can afford to be choosy; a complete record of products, rates, withholding periods and SWNZ-ready data is part of what makes your fruit the fruit they keep.
• Decide on vine removal with data, not just vine age. Yield history, disease pressure and the cost of working each block show which ones to pull, rework or redevelop.
• Talk to your winery early about the 2027 intake. Marlborough companies have signalled similar restrictions next year; knowing the tonnage before spring lets you set crop levels in the vineyard rather than leave fruit hanging.

What wineries can do now

• Know exactly what is in tank and in the bottle store, by lot, variety, vintage and region. In an oversupplied market, bulk wine that can be sold quickly is worth more than wine you have to find first.
• Watch export eligibility dates. Under MPI’s Wine Notice: Export Requirements and Exemptions, export eligibility for a batch of NZ grape wine is valid for up to 2 years for packaged wine but only 3 months for bulk wine. Bulk stock held while you look for a buyer may need to be re-applied for.
• Keep the traceability to back label claims. Wine sold into new markets — or blended to move surplus — still needs the vineyard-to-bottle chain your WSMP requires.
• Track the cost of each lot. Additions, ageing, storage and bottling costs per litre tell you the lowest price at which a bulk sale still makes sense.

The outlook

New Zealand Winegrowers’ chair Fabian Yukich describes an industry “moving towards a more balanced footing”, and the smaller 2026 crop is a step in that direction. But with intake restrictions likely again in 2027, US tariffs still uncertain and new markets such as India taking years to build, the next few seasons will reward businesses that know their numbers at block and lot level.

That is what GrapeFlow is built for: blocks, the spray diary and harvest intake on the vineyard side; tanks, barrels, additions, blends and bottled stock in the cellar; all traced lot by lot. It doesn’t forecast prices or negotiate contracts, but it gives you the records to do both with confidence.
