Information on the settlement times, location, growth rates, and density, etc., of more than 40 species was tabulated. Settlement was found to occur at all seasons although numbers and species varied. Serpulids and some polyzoa settled in the summer, and algal species mostly in the winter. At each station one barnacle species settled throughout the year #(Chamaesipho columna# at Piha, #Elminius modestus# at Narrow Neck and West Tamaki Head), other species settling over a more limited season. Settlement of individual species differed on the two coasts; certain animals which settled throughout the year on the west coast (Piha) settled mainly in the spring on the east coast (#Perma canaliculus#, #Chamaesipho columna#). On the east coast mussels settled during winter and spring, oysters in summer and autumn. Most of the organisms settled and grew on bare rock, either on newly cleared surfaces, or on bare areas on surfaces cleared up to 2 years before. #Perna canaliculus# settled only when there was protection from desiccation. The general pattern of seasonal settlement was similar each year, but the actual time and amount of settlement of any one organism varied from one year to the next. Time of settlement of one species at different levels on the same shore also varied
