History and culture

European settlement

J. S. Cotterell surveyed the Wairau Valley in November 1842, and reported it contained rich land.^[7] Settlers from 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.^[8]

In November 1846, Nelson farmers Nathaniel Morse and John Cooper drove sheep into the Wairau valley^[9] 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.^[10]

In the 1855 Wairarapa earthquake, the eastern end of the Wairau valley subsided by over a metre.^[11]

Marae

Parerarua Marae is located in Wairau Valley. It is a marae (meeting ground) of Ngāti Rārua and includes the Parerarua wharenui (meeting house).^[12][13]

In October 2020, the Government committed $246,418 from the Provincial Growth Fund towards renovating the marae, creating an estimated 7 jobs.^[14]
