I re-visited Waiwera today after checking out the foreshore at Shoal Bay.
That sign at Waiwera read that in the 2013 breeding season out of 21 eggs only 12 chicks were hatched and then only one chick survived.
They put the low survival rate down to human and dog disturbance. Constant disturbance of the birds from their nests to lead people away from the nests so reducing successful chick production is the problem.
This area will now become a No Dogs area. They are waiting for the signs to go up.
