Auckland Council has spent over half a million dollars and is engaged in a legal battle with itself in a bid to build a controversial seawall in Orewa.
The council had applied to itself, as the consenting authority, to build a 600m seawall in the northern part of the beach.
However an independent panel of commissioners rejected the resource consent application last December.
In its decision the commissioners said a "hard structure", such as a seawall, should only be a "last resort". If built, it would adversely affect coastal processes, public access, natural character and the appearance of the area.
