The commercial hub of Marlborough (population 42,300) is Blenheim (population 28,200). Originally a provincial service town to the farming community, it is increasingly geared towards urban lifestyle, visitor needs and the dominant wine industry, a meld of modern sophistication and relaxed ambience. North is Picton (population 3,700), seaport gateway to the stunning Marlborough Sounds.
Blenheim is the focal point for the Marlborough wine growing region. A number of wineries are located on the towns edges, with many more just a short drive away.
