Ōhau River (Canterbury)
river in Canterbury Region, New Zealand
The Ōhau River is a river in the Mackenzie Basin of New Zealand's South Island. It is the primary outflow of Lake Ōhau, from which it flows in a roughly eastward direction until reaching the artificial Lake Benmore after a distance of roughly 27 kilometres (17 mi). In 1981, the artificial Lake Ruataniwha was created along the river's length to power a small hydroelectric power station as part of the Waitaki hydro scheme. Prior to the creation of the Waitaki hydro scheme, the river flowed directly into the Waitaki River rather than through a series of lakes. The river forms part of the traditional boundary between Otago and Canterbury regions.
Prior to European settlement of the region, the river was a traditional mahinga kai (food gathering site) for Māori travelling through the Mackenzie Basin, providing valuable food sources such as weka, tuna (eels), and pora (Brassica rapa subsp. sylvestris).
This brief starts where responsible research should: with the source description of “Ōhau River (Canterbury)” as river in Canterbury Region, New Zealand. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as river in Canterbury Region, New Zealand. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Mar 23, 2025. The linked authority identifier is Q7080632. Authority coordinates are -44.350, 170.200. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1981.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
