The Wairau Valley is the heart of Marlborough’s wine country — and Marlborough produces about 75% of New Zealand’s wine and is the country’s most internationally recognised wine region, particularly for sauvignon blanc. From Blenheim, the established sub-zones at Rapaura and Renwick (just 12 km west) put you within easy driving or cycling distance of more than 30 cellar doors. This page covers the practical side of a Wairau Valley wine day — where to start, how to move between wineries, and what’s distinctive about the region.

About Marlborough Wine
Marlborough is by a significant margin New Zealand’s largest wine region, producing about 75% of the country’s total wine output. The region’s reputation rests overwhelmingly on Sauvignon Blanc — Marlborough Sauvignon Blanc is one of the few NZ products with genuine international brand recognition, characterised by tropical fruit, grapefruit and gooseberry notes coming from the well-drained, stony soils of the Wairau Valley and the moderating influence of sea breezes off Cloudy Bay.
While sauvignon dominates planted area, Marlborough also produces significant volumes of Pinot Noir, Chardonnay, Pinot Gris, Riesling and small amounts of aromatic varieties. Some of the most established Pinot Noir comes from the Awatere Valley to the south rather than the Wairau Valley, but Wairau remains the production heart of the region.
The Wairau Sub-Zones
Within the Wairau Valley, two named sub-zones are the most established and have the most concentrated cellar door clusters:
Rapaura — to the north of Blenheim, with the gravel-rich free-draining soils that produce some of the most characteristic Marlborough sauvignon. Many of the largest wineries are based here.
Renwick — 12 km west of Blenheim, the small village that has become Marlborough’s most concentrated cellar door cluster. Renwick is also the standard base for self-guided cycling tours — bike hire is available locally and most cellar doors in the village are within 5-10 minutes of each other by bike.
The wider Wairau Valley extends west of Renwick into the upper valley, with vineyards and a few cellar doors stretching toward the foothills, but the visitor density drops off the further west you go.
How to Visit
The two practical approaches are: drive yourself with a designated driver, or book a wine tour. For visiting on your own steam, basing from Renwick and using bikes between cellar doors works well — the 5-10 minute spacing between most Renwick wineries makes for an easy half-day or full-day loop. For larger groups or anyone wanting to taste at multiple Rapaura wineries (which are more spread out), guided tour vans are more practical.
Most cellar doors open from late morning to mid-afternoon (typically 10am to 4 or 5pm). Tasting fees vary — many are now small charges that are waived with purchase. The peak season runs through spring and summer (October to April).
