The Whanganui electorate is one of the oldest electorates in the country, it was formed in 1860 when the Wanganui-Rangitikei seat was split in two.
Whanganui itself is by far the largest town with a population of around 40,000. From there the electorate reaches north and includes many small towns and settlements including Patea, Manaia, Eltham, Hāwera, right up to Stratford at the foot of Mt Taranaki.
With so many towns in its boundaries, courting votes involves plenty of time on the road.
A boundary shift in 2008 to include the town of Stratford compensated for the electorate's dwindling population. A decline that saw rural towns lambasted by media and economic commentators as "Zombie towns" due to their declining population. However, that trend is now in reverse.
