farther in the interior into conglomeratic clays, together with dikes of 
anamesite and basalt. 
b) South of Manukau Harbour on both sides of the Waikato and thence as 
far as Aotea Harbour basaltic conglomerates and basalt; without any 
distinct cone and crater formation. 
c) The volcanic table-land between the Upper and Middle Waikato Basin ;
