5.2.5 Economics of the Work
The costs associated with this restoration project of a 150-m length of foredune
included NZ$ 2,400 in consultancy fees, NZ$ 1,700 in heavy machinery hire, and
planting and fencing at a cost of NZ$ 40 per linear meter (year 2000 prices).
5.3 Case Study 2: Foredune Restoration, East End Beach
East End Beach (New Plymouth, Taranaki Region, North Island, New Zealand) is
a moderate- to high-energy coastal system that also has a very limited sediment
supply. It comprises a wide, rocky, predominantly sub-tidal reef thinly overlain
with sand in the surf zone and on the beach. Prior to restoration, the dune system
comprised one erosional, relatively low, narrow foredune (Fig. 5.6). The foredune
regularly displayed an erosion scarp along its length and had been significantly
altered in the past by widening, leveling, and filling. It had been impacted by port
works (to the south) and subsequent loss of sediment from the littoral drift system.
Following the short-term success of the Oakura restoration works, the New
Plymouth District Council undertook to reshape and restore the foredune with the
