Seddon is a small town in Marlborough, New Zealand. It is located on State Highway 1, 25 kilometres (16 mi) south of Blenheim and 20 km (12 mi) north of Ward. Seddon is located close to the mouths of the Awatere and Blind Rivers, and also close to the Lake Grassmere salt works.[1][2]

Salt and lime[3] are major local industries, and the Awatere Valley is a developing wine region.[4]

The population was 510 in the 2006 Census, an increase of 36 from 2001.[5]

The town's best known structure is a joint single-lane road-rail bridge spanning the Awatere River which was in service until October 2007. A two lane road bridge has replaced the road bridge component.[6] The railway line continues over the old historic bridge which is the Main North Line and a daily service in each direction of the TranzCoastal passenger express stops in Seddon.

A train derailment at Blind River, south of Seddon, on 25 February 1948, killed six people and injured 40 others.[7]

The town was named for a former Prime Minister of New Zealand, Richard Seddon.


Seddon has been close to the epicentres of several significant earthquakes.

On the morning of 16 October 1848, Marlborough was struck by a damaging earthquake later estimated to be between magnitude 7.4 and 7.7.[8] The epicentre of this earthquake was 45 km southeast of Seddon.[9]

On 23 April 1966, a magnitude 5.8 earthquake with an epicenter in Cook Strait, 40 km east of Seddon[10] was most strongly felt in the town, damaging the chimney on almost every house in town.[11]

In July and August 2013 Seddon was closest settlement to the epicentres of a doublet earthquake event.[12] First, in late July, a series of sizeable earthquakes struck the region over a period of a few days being felt strongly in Blenheim, Wellington and the rest of Central New Zealand, the strongest being a magnitude 6.5 and having its epicentre in Cook Strait.[13] Then on 16 August 2013 a magnitude 6.6 earthquake with its epicentre under Lake Grassmere struck about 2:30 PM [14] and was followed by a series of aftershocks over the next few hours, one of which was above magnitude 6 and several others above magnitude 5. This came just a few years after devastating earthquakes affected Christchurch, 285 km away.[15]


Seddon School is the sole school in the town. It is a coeducational full primary (year 1–8) school with a roll of approximately 119.[16] The nearest state secondary schools are Marlborough Boys' College and Marlborough Girls' College in Blenheim.

Trains use the upper level of the bridge. Road transport used the lower level until a new bridge was opened in November 2007.
