Nelson is a New Zealand parliamentary electorate, returning one Member of Parliament to the House of Representatives of New Zealand. From 1853 to 1860, the electorate was called Town of Nelson. From 1860 to 1881, it was City of Nelson. The electorate is the only one that has continuously existed since the 1st Parliament in 1853.
The current MP for Nelson is Nick Smith of the National Party. He has held this position since 1996.
Nelson is based around the city of Nelson, with the dormitory town of Richmond and the smaller communities of Hope and Brightwater drafted in to bring the electorate up to the required population quota.
A significant adjustment to the electorate's boundaries was carried out ahead of the change to Mixed Member Proportional (MMP) voting in 1996; the decrease in South Island electorates from 25 to 16 lead to the abolition of one western South Island electorate; Tasman was split between West Coast and the then (geographically) much smaller Nelson electorate.
The Representation Commission last adjusted the boundaries in the 2007 review, which first applied at the 2008 election; the electorate was not changed in the 2013/14 review.
An electorate based on the Nelson has been contested at every election since the first Parliament in 1853. Two of the original 24 electorates from the 1st Parliament still exist (New Plymouth is the other one), but Nelson is the only original electorate that has existed continuously.
