This district covers the area which, before drainage, contained the swamplands of the Hauraki Plains. Its eastern boundary is generally the Waihou River, and its western boundary is the boundary of the Waikato Confiscation District. To the south the district encompasses a number of Crown purchases known as the Hangawera and Waitoa purchases, plus some purchases by private individuals on the drier lands. This places the district boundary just to the north of Matamata.
Blocks in this district that have not been researched are primarily a series immediately fronting on to the Waihou River, most of which were purchased by private individuals.
