Kiwifruit Insurance: Protecting Your Orchard from PSA and Weather Events

The Kiwifruit Industry and Its Risks

New Zealand is the world's third-largest kiwifruit producer, with the Bay of Plenty region at the heart of a $3+ billion export industry. The industry has come a long way since PSA (Pseudomonas syringae pv. actinidiae) devastated orchards in 2010–2013, but growers today face an evolving range of risks that make robust insurance cover essential.

The kiwifruit industry is dominated by Zespri — the grower-owned marketing company that manages NZ kiwifruit exports globally. Most commercial orchards grow either Zespri Green (Hayward variety) or the premium Zespri SunGold (Gold3 variety). Gold kiwifruit orchards command higher land values and higher revenues per hectare, but also represent a larger insurance exposure given the significant investment in variety licensing and orchard development.

PSA Disease Coverage: Understanding Your Options

PSA cover is one of the most frequently asked-about topics in kiwifruit insurance. The challenge is that PSA is a biological disease, and most standard named perils policies explicitly exclude disease coverage. This reflects the fundamental difficulty insurers have in distinguishing between natural disease events and management failures. However, several meaningful options exist:

Business interruption cover is arguably the most important disease-related protection available to kiwifruit growers. If a PSA outbreak — or another significant disease event — forces a material reduction in your orchard's productivity over one or more seasons, business interruption cover can compensate for lost revenue during the recovery period. This type of cover does not require the cause to be a named peril; it responds to the financial impact of an operational disruption.

Re-establishment costs are covered under some specialist policies. If PSA or another disease forces vine removal, soil treatment, and replanting, the cost of this remediation work can reach $40,000–$80,000 per hectare. Select policies will contribute to these costs, particularly if the outbreak is confirmed as an incursion from outside your property.

Specialist disease cover is available from select international markets accessed through brokers like Gallagher and Aon. These products are typically structured as standalone disease covers with specific trigger definitions, waiting periods, and significant sub-limits. They are not cheap, but for large gold kiwifruit operations they can provide meaningful protection.

Weather Events: The Bigger Annual Risk

While PSA grabs headlines, weather remains the most consistent annual threat to kiwifruit orchards in the Bay of Plenty and other growing regions:

Hailstorms

Hailstorm damage is the single most commonly claimed weather event across NZ's kiwifruit sector. A hailstorm at flowering — typically September to October — can shred petals and prevent fruit set. Hail during vine growth scars the developing fruit, rendering it unfit for Zespri's fresh market export grades even if the fruit is otherwise healthy.

Hail netting provides meaningful physical protection but is itself an expensive asset — installation costs typically run $30,000–$80,000 per hectare depending on system type and terrain. The netting itself must be insured, and hail events can cause significant net damage that requires repair or replacement before the following season.

Late Frosts

Frosts in the Bay of Plenty are infrequent by NZ standards, but when they occur during budburst or flowering they can destroy 80–100% of a crop in a single night. The risk is particularly acute in lower-lying orchard sites where cold air pools overnight. Active frost protection — helicopter contracts, sprinkler systems — is common on the most frost-exposed Bay of Plenty sites.

Cyclone and Wind Events

Cyclone Gabrielle in February 2023 caused significant damage to Bay of Plenty kiwifruit orchards. Wind damage to infrastructure — hail nets, trellis wires, packing sheds — was widespread, and some low-lying orchards suffered flood and silt damage. This event reinforced the importance of ensuring that cyclone and windstorm perils are explicitly included in your kiwifruit insurance programme, and that sum insured values include all infrastructure at replacement cost.

Waterlogging and Flooding

Kiwifruit vines are highly sensitive to waterlogged soils. Extended flooding can cause vine death that is not immediately apparent — the visible damage may only emerge weeks after the water recedes. Policies need to be clear about the timing of damage assessment for flood events to ensure valid claims are not declined on a technicality.

What a Good Kiwifruit Policy Looks Like

A comprehensive kiwifruit orchard insurance programme typically includes:

1. Standing crop cover — hail, frost, wind, fire, flood. The core of any kiwifruit policy.

2. Orchard infrastructure — hail nets, irrigation systems, trellis, packing shed. Often held under a separate farm or commercial property policy but should be coordinated with crop cover.

3. Business interruption — loss of orchard income during recovery from a covered event. Critical for events that damage the vine itself rather than just the current season's crop.

4. Post-harvest quality cover — losses from cool store failures, temperature excursions, or handling failures after harvest. Complements crop cover for the post-harvest period.

5. Public and product liability — essential for any commercial operation with employees, contractors, or visitors on-site, and for product liability exposure.

Understanding Zespri Quality Standards and Their Insurance Implications

Kiwifruit insurance claims are assessed against Zespri's grading standards for the relevant variety. A key point for growers: the difference between Class 1 (export grade) and Class 2 or processing-grade kiwifruit is the difference between $8/tray and $1–2/tray. Hail-scarred fruit that cannot meet Class 1 standards creates a significant revenue loss even if 100% of the physical crop is harvested.

Your insurance policy should be structured to compensate for this downgrade — not just physical crop loss. Discuss how the policy handles quality downgrade losses with your broker before you purchase.

Getting a Quote

Given the complexity of kiwifruit insurance — with its combination of disease risk, high infrastructure value, post-harvest exposure, and Zespri grading standards — we strongly recommend working with a specialist horticulture insurance broker.
