Marlborough Crop Insurance

Crop Insurance in Marlborough

Marlborough is New Zealand's largest and most internationally celebrated wine region, accounting for approximately 75% of NZ's total wine grape production. The Wairau and Awatere valleys produce Sauvignon Blanc, Pinot Gris, Riesling, and Pinot Noir sought after by wine lovers globally.

Frost Risk in Marlborough Vineyards

Frost is the dominant crop insurance risk for Marlborough growers. The Wairau Plain's relatively flat topography and cold, clear spring nights create significant radiation frost risk from budburst (typically August–September) through to November. A severe frost event can cause near-total crop loss across multiple properties in a single night.

Frost protection infrastructure — wind machines, helicopters, overhead irrigation — reduces risk but is expensive and imperfect. Insurance is the backstop.

Hail Risk in Marlborough

Convective hailstorms occur across Marlborough during the growing season and can cause severe localised damage to grape clusters. Hail at berry development stage punctures skins, leading to botrytis infection and complete loss of affected bunches.

Marlborough Insurance Market

Marlborough has a well-developed viticulture insurance market, with FMG, Aon, and AJG all active in the region. Frost cover is standard; hail cover for vineyards is also widely available. Following recent significant frost events, premiums for frost-exposed sites have increased but remain available.
