This plain slopes back to thebase of the low downs near Amberley, where it reaches^a height of about150 ft However, on looking up the coast to the north from the mouthof the Waipara, decided remnants of a shore platform can be seen at anestimated height of 250 ft. above the sea, and fronting the plain thereTre several small remnants at lower levels marking stationary periodsduring the prolonged elevation. It is therefore certain that a long stretchof coast-line has experienced the effect of this movement. That the useif ofdecent date is Ly clear from the species of shells found at Motunau,and also from the forms of the stream-valleys that have been esta-blished on the elevated marine shelf. With few exceptions the streamswhich run across it have very short courses, and are little more thanextended sullies or washouts. Through the somewhat loose Motunaumark
