Westland Boroughs was a parliamentary electorate in the West Coast of New Zealand from 1866 to 1870.
The enabling legislation allowed for further boroughs to be added as needed, but this did not happen.
Waimea lost some area, but continued to exist as a landlocked electorate.
A new electorate (Westland Boroughs) was established, and the Act stipulated that the sitting member (William Sefton Moorhouse) was transferred to it.
Moorhouse resigned on 20 February 1868,[4] and William Henry Harrison won the resulting by-election.
