# West Coast-Tasman

West Coast-Tasman is a New Zealand parliamentary electorate, currently held by Maureen Pugh of the New Zealand National Party as of the 2023 general election. West Coast-Tasman is the largest general electorate in the entire country, with an area larger than the entirety of Belgium. It comprises the entirety of Te Tai Poutini and the Tasman District, as well as Brightwater in suburban Nelson.
Historically it has often been regarded as one of the safest New Zealand Labour Party seats in the entire country. From its creation for the 1996 election until 2023, it was held by Damien O'Connor of the Labour Party, with the exception of one parliamentary term under National's Chris Auchinvole (between 2008 and 2011). Pugh's narrow victory in 2023 (915 votes) was considered a major upset, with the third-place independent candidacy of Patrick Phelps splitting the vote in her favour.

## Population centres

West Coast-Tasman is the largest general electorate in New Zealand, covering 32,758 km$^2$ (12,648 sq mi). It is one of the longest. The Representation Commission last adjusted the boundaries in the 2007 review, which first applied at the 2008 election, when the northern boundary moved closer to Nelson, and Wakefield, Foxhill and Belgrove were added. The electorate was not changed in the 2013/14 review. Brightwater was added from Nelson at the 2020 redistribution.
The electorate includes the following population centres:
* Collingwood
* Tākaka
* Motueka
* Tapawera
* Brightwater
* Wakefield
* Westport
* Reefton
* Greymouth
* Hokitika
* Ross
* Hari Hari
* Whataroa
* Franz Josef / Waiau
* Fox Glacier
* Haast

## History

The electorate was formed in 1996 for the mixed-member proportional (MMP) voting system by combining the former Tasman and West Coast electorates.
Damien O'Connor was the first representative and he held the electorate until the 2008 general election, when he was beaten by National candidate Chris Auchinvole, who had previously been a list MP. Auchinvole's majority was 971. His position on the Labour Party list meant that O'Connor couldn't return to Parliament immediately. When the list MP Michael Cullen retired in May 2009, O'Connor regained his position as Member of the House of Representatives because he was the highest-ranked candidate on the list not already an MP. In contrast to the overall trend, he regained the electorate in the 2011 election.
Auchinvole retired from politics at the end of the 2011–2014 parliamentary term, and former Mayor of Westland District, Maureen Pugh, gained the nomination for the National Party. O'Connor was once again successful. Based on preliminary results for the 2014 election, Pugh was the lowest-ranked National Party list member who was returned to Parliament, but when the final results were released two weeks later, National had lost one list seat and Pugh did not get returned to Parliament.
