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
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
- 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.
