The future of the Ban 1080 Party, which draws most of its votes from the West Coast-Tasman electorate, will be reassessed after an abysmal result at the ballot box on Saturday.
Nationally, the party vote fell to just 2440 - down from 5113 when Ban 1080 made its political debut at the 2014 general election.
West Coast-Tasman candidate Peter Salter, of Pukekura, again won the lion's share of their party vote, but it was nowhere near enough.
Even so, his own vote plummeted from 2318 last election to 1316, while the party vote collapsed from 942 to just 306.
Party founder Bill Wallace, of Golden Bay said the only party candidate to show an increase at the polls was well known anti-1080 campaigner Clyde Graf, in Coromandel.
