The Waikawa Stream flows west towards the sea but then turns south across the beach. A 1991 rock groyne has submerged and a 2012 rock groyne at almost right angles has had bad results. Today two diggers excavated rock from the ‘bad’ groyne and piled it up on the ‘good' groyne.

Two diggers side by side excavating rocks and piling them up nearby. Wide view showing river and diggers.
