For something different drive along the coast road out of Kaikoura until you come to the end of the road at DOC carpark.  Leave your car and go for a walk on the wave platform.  A bit restricted at high tide but other wise a wide range of rock pools,fish, birds  and seals just doing their thing on the edge of the sea.  Arriving in the evening allows for the light to be fantastic as the sun sets behind the mountains.
