Rangitaiki Drainage Scheme

The Rangitaiki Drainage Scheme provides benefits of gravity drainage to much of the land on the Rangitaiki Plains.

The Rangitaiki Plains covers an area of 27,000 ha between Matata and Whakatane, extending from the coast to Kawerau and covers the lower flood plains of the Rangitaiki, Tarawera and Whakatane Rivers.

The predominant land use is dairying, horticulture and grain cropping. There are also small areas of wetland reserve and urban development. Prior to European settlement in 1890 the Rangitaiki Plains consisted mostly of wetlands.

The total value of the scheme is approximately $4.4 million (scheduled for review). The costs of capital works and scheme maintenance is solely provided by the scheme ratepayers. The Rangitaiki Drainage Scheme Asset Management Plan sets out the management guidelines of scheme assets.

The scheme consists of:

  • 328 kilometres of major canals and drains servicing 27,000 hectares
  • Culvert and flapgate structures at 22 locations
  • 1100 metres of low stopbanks
  • Four erosion control structures

This does not include assets of the Rangitaiki-Tarawera or Whakatane-Waimana Rivers Schemes or the 34 separate communal pumping schemes, which also service the Rangitaiki Plains. Significant issues facing the scheme are subsidence, conservation values and weed control.
