Tom and Wiremu have been reading an article abut st Clair's sand dune loss. Since the 24th of July 2015 the dunes have lost approximately 5 metres of sand. The sand sausages that were placed in the sand dunes have been dug up by erosion. The worry for the sand dunes are the spring king tides. They come when it is a new full moon at the same time the moon is at its closest to the earth.
