estuaries are well flushed, with little diversity in the way of intertidal and subtidal habitats.
Sedimentation has a major influence on the region’s estuaries, the factors behind which
include rain fall and modified land use. The large number of rivers and the erosion of
Mount Taranaki generally bring a lot of sediment to the coast. However, the high energy
coastline means this sediment supply does not settle long enough to greatly assist with
the beach building process.

flow past the weir (constructed in 2002). The remaining residual flow passes through an old (and mostly
ineffective) fish pass on the true left bank of the weir.
Much of the scheme is monitored and operated remotely by the Company. Through a computerised water
level sensor system, Trustpower can monitor the residual flows in the Manganui River and Mangaotea
Stream, water levels in the race and lake and how much rain is falling locally. This has allowed Trustpower to
manage race flows to

the Stage 2 irrigation area. This is consistent with rapid wastewater infiltration through approximately 2 m of
sandy soil to the underlying water table. The levels of ammonia present are very low, indicating almost
complete nitrification in aerobic soil. The significant fall in nitrate concentration during the 2010-2011
monitoring period in MP2, was in response to reduced irrigation volumes, and since has ranged between
about 10 and 20 g/m³N. During

includes mahoe (Melicytus ramiflorus subsp. ramiflorus), wineberry
(Aristotelia serrata), raukawa (Raukaua edgerleyi), rangiora (Brachyglottis
repanda), pigeonwood (Hedycarya arborea), mountain cabbage tree
(Cordyline indivisa) and hangehange (Geniostoma ligustrifolium var.

seedlings and saplings are also common. The area falls within the ‘Less
