Tuamarina

Tuamarina (often spelled Tua Marina) is a small town just north of the Wairau River and a few kilometres from the Cloudy Bay coast in Marlborough, New Zealand. The Tuamarina River flows south through the settlement and joins the Wairau River. State Highway 1 runs through the town, with Blenheim 10 km to the south and Picton 18 km to the north.

The name is a corruption of the Māori word Tuamarino, which means 'the calm beyond'. The Wairau Affray, with 26 deaths, occurred in the area in 1843.

Dairy farming is the major economic activity. The original factory was the Waitohi Co-op, which amalgamated with the Koromiko cheese factory and the Rai Valley Co-op to form the Marlborough Cheese Company in 1981. The new company continued Waitohi's long history, winning a number of awards. It was taken over by Fonterra Dairy Company in 1999 and the factory destroyed by fire in 2004.

The Wairau Plain is prone to flooding, and river conservation is necessary to keep the river under control. Significant floods have occurred in the area, such as one in December 1939.
