'''Wairau Valley''' is the valley of the [[Wairau River]] in [[Marlborough District|Marlborough]], New Zealand and also the name of the main settlement in the upper valley. [[New Zealand State Highway 63|State Highway 63]] runs through the valley. The valley opens onto the Wairau Plain, where [[Renwick, New Zealand|Renwick]] and [[Blenheim, New Zealand|Blenheim]] are sited.<ref>{{cite book|title=Reed New Zealand Atlas|year=2004|isbn=0-7900-0952-8|editor=Peter Dowling |publisher=Reed Books|pages=map 59}}</ref><ref>{{cite book|title=The Geographic Atlas of New Zealand|year=2005|isbn=1-877333-20-4|author=Roger Smith, GeographX|publisher=Robbie Burton|pages=map 138}}</ref> The [[Alpine Fault|Alpine]]–[[Wairau Fault]] runs along the length of the valley.<ref>{{cite book|title=Click - A Captured Moment - Marlborough's Early Heritage|author=Marlborough Historical Society|year=2005|isbn=0-473-10475-X|pages=16}}</ref>

==History and culture==

===European settlement===

J. S. Cotterell surveyed the Wairau Valley in November 1842, and reported it contained rich land.<ref>{{cite encyclopedia|url=http://www.teara.govt.nz/TheBush/UnderstandingTheNaturalWorld/EuropeanExploration/5/en|title=Thomas Brunner, Nelson and the West Coast|encyclopedia=[[Te Ara: The Encyclopedia of New Zealand]]}}</ref> Settlers from [[Nelson, New Zealand|Nelson]], led by [[Arthur Wakefield]], tried to take possession of the land but the [[Ngāti Toa]], led by [[Te Rauparaha]] and [[Te Rangihaeata]] objected. The dispute escalated into the [[Wairau Affray]] at [[Tuamarina]] on 23 June 1843, in which 22 settlers and four Māori were killed. An enquiry held in 1844 by Governor [[Robert FitzRoy]] decided that the settlers were in the wrong.<ref>{{cite encyclopedia|url=http://www.teara.govt.nz/Places/Wellington/Wellington/7/en|title=The struggle to survive: 1840–1865|encyclopedia=[[Te Ara: The Encyclopedia of New Zealand]]|access-date=28 May 2008|archive-date=1 May 2009|archive-url=https://web.archive.org/web/20090501155308/http://www.teara.govt.nz/Places/Wellington/Wellington/7/en|url-status=dead}}</ref>

In November 1846, Nelson farmers [[Nathaniel Morse]] and John Cooper drove sheep into the Wairau valley<ref>{{cite web| title=Marlborough region - Grazing and farming |first=Malcolm |last=McKinnon |url= http://www.teara.govt.nz/en/marlborough-region/page-6 |publisher=[[Te Ara: The Encyclopedia of New Zealand]] |access-date=21 August 2013 |date=13 July 2012}}</ref> and established settlements. Governor Sir [[George Grey]] purchased the land in the same year, but legal title to the land for the settlers was sorted out later.<ref>{{cite book|title=Marlborough - A Provincial History|editor=A. D. McIntosh|year=1940|pages=93, 131–134}}</ref>

In the [[1855 Wairarapa earthquake]], the eastern end of the Wairau valley subsided by over a metre.<ref>{{cite encyclopedia|url=http://www.teara.govt.nz/EarthSeaAndSky/NaturalHazardsAndDisasters/HistoricEarthquakes/3/en|title=The 1855 Wairarapa earthquake|encyclopedia=[[Te Ara: The Encyclopedia of New Zealand]]|access-date=28 May 2008|archive-date=21 February 2009|archive-url=https://web.archive.org/web/20090221195734/http://www.teara.govt.nz/EarthSeaAndSky/NaturalHazardsAndDisasters/HistoricEarthquakes/3/en|url-status=dead}}</ref>
