All branches align with electorate boundaries with the exception of Wairarapa Branch, which excludes Central Hawke's Bay District which is part of Hawke's Bay Branch, Central Province. This region includes Wellington Province's portions of Ikaroa-Rāwhiti, Te Tai Hauāuru and Te Tai Tonga Electorates.
Errata: The Te Tai Tonga and Rongotai Electorates, as well as Wellington Province, all include the Chatham Islands. Crossing longitude 180 is not properly supported by mapping software, so these maps will appear odd/broken until you zoom in close enough to a feature to exclude longitude 180 from the frame.
