Market
Dried hops in New Zealand are a specialized brewing ingredient supply chain concentrated in the Nelson–Tasman region, with export-oriented production alongside domestic brewery demand. New Zealand Hops Ltd, a grower cooperative, reports exporting to over 20 countries, with key markets including the USA, UK, Australia, and Asia. Harvest is typically in late summer (late February to March), followed by drying, cold storage, and (commonly) pelletising and vacuum/inert-gas packaging to preserve aroma and bitterness compounds. New Zealand’s global hop-market presence is small (reported as around 1% in a New Zealand industry release), but the country is positioned as a niche supplier of distinctive aroma varieties.
Market RoleProducer and niche exporter (specialty aroma hops)
Domestic RoleCore brewing input for domestic beer production, with commercial supply also directed to export markets
Market GrowthNot Mentioned
SeasonalityLate-summer harvest with processing (drying/pelletising) concentrated in late February to March; availability thereafter depends on cold storage and packaged inventory.
Specification
Primary VarietyNelson Sauvin
Secondary Variety- Motueka
- Riwaka
- Wakatu
- Pacific Jade
- Green Bullet
- Cascade
Physical Attributes- Supplied as whole dried hop cones (pressed bales) and/or pellets (Type 90), with quality preservation emphasized through cold storage and oxygen-limiting packaging.
Compositional Metrics- Moisture content checks and sampling for grading/chemistry are used at intake and during handling; alpha-acid and oil-related chemistry are common buyer specification anchors.
Grades- Grading commonly references moisture and chemistry sampling to support buyer specifications for brewing performance.
Packaging- Pressed whole-cone bales held in cold storage; can be shipped under refrigeration
- Vacuum-packed whole cones in aluminium barrier foil packs for long-term stability (for smaller-quantity users)
- Vacuum-packed Type 90 pellets in aluminium-foil liners with nitrogen backflushing (commonly 5kg, 20kg, or 25kg cartons)
Supply Chain
Value Chain- Late-summer harvest (Nelson–Tasman) → drying → moisture/chemistry checks and grading → cold storage → pelletising (Type 90) or whole-cone preparation → nitrogen/inert-gas backflush and vacuum packaging → refrigerated export shipment → brewer/importer cold storage and use
Temperature- Cold storage is used post-harvest to preserve hops at peak freshness
- Refrigerated shipment is used for some whole-cone and export movements to protect aroma quality
Atmosphere Control- Pellets are commonly vacuum packed and backflushed with inert gas (nitrogen) to reduce oxidation and retain aromatics
Shelf Life- Vacuum-packed whole cones and inert-gas/vacuum-packed pellets are positioned for improved long-term stability during storage and distribution

Risks
Regulatory Compliance HighExport shipments can be blocked or delayed if the destination market’s ICPR phytosanitary requirements are not met or if required phytosanitary certification/documentation is incomplete. MPI notes overseas requirements often change, and the MPI ePhyto portal indicates a transition to MPI Trade Certification for new phytosanitary certificate requests starting 2 March 2026, creating additional operational change risk for exporters relying on timely certification.Lock the latest destination ICPR with the importer before contracting/booking freight; run pre-shipment compliance checks (product form, treatments if any, and documentation); build timeline buffers around certification and system/process transitions.
Climate MediumA concentrated growing footprint in the Nelson–Tasman region increases sensitivity to adverse seasonal weather during late-summer harvest windows, which can reduce yields and disrupt drying/pelletising schedules.Diversify contracted supply across multiple growers within the region; maintain safety stock in cold storage and use forward contracts tied to harvest reports.
Logistics MediumQuality preservation relies on cold storage and oxygen-limiting packaging; long-distance exports from New Zealand can face service disruptions (container availability, route delays) that raise delivered costs and create out-of-spec quality risk if cold-chain discipline is broken.Specify cold-chain and packaging requirements in contracts (vacuum/inert-gas packaging, refrigerated handling where needed); use validated logistics partners and monitor temperature/handling conditions through shipment milestones.
Sustainability- Verification of integrated pest management and any spray-free/organic claims (New Zealand Hops describes low-impact IPM and availability of organic production).
- Environmental stewardship expectations from international brewers (some growers publicly emphasize long-term environmental wellbeing alongside expansion and processing investment).
Labor & Social- Seasonal labor intensity during training and harvest in hop gardens; labor availability and safe operations during harvest can affect processing throughput and shipment timing.
Standards- On-farm GAP-style certification programs (auditable) referenced by New Zealand Hops
- HACCP (processing and cold storage) referenced by New Zealand Hops
- ISO 9001:2015 quality management system certification (example: New Zealand Hops; certified by Bureau Veritas per company statement)
- Kosher (Parve) certification for certain hop products (example: New Zealand Hops)
- U.S. FDA registration stated by a major exporter (New Zealand Hops)
FAQ
When are hops typically harvested and processed in New Zealand for dried-hop supply?Industry sources describe late-summer harvest timing, with New Zealand Hops stating harvest in late February and March. After harvest, hops are dried and then commonly placed into cold storage; they may be pelletised and vacuum/inert-gas packed to preserve aroma and brewing performance.
What phytosanitary steps matter most when exporting dried hops from New Zealand?MPI advises exporters to meet the importing market’s phytosanitary requirements using ICPR documents, noting requirements can change. If the destination ICPR requires it, exporters obtain a phytosanitary certificate through MPI’s plant export certification process (ePhyto / MPI Trade Certification workflow).
What product forms are common for New Zealand’s commercial dried-hop exports?New Zealand Hops describes supplying whole cone hops and Type 90 hop pellets, with cold storage and vacuum/inert-gas packaging used to retain freshness. The same exporter also describes supercritical CO2 hop extract as an additional hop product form for brewers.
