"And we need to remind voters that the election for the Whanganui District Health Board is on the Single Transferable Voting (STV) system which requires voters to number the candidates in order of preference. They must not be ticked. Any voting paper that is ticked immediately becomes invalid," she said.
In 2007, nearly 7 per cent of votes - 1747 of them - were disallowed because voters had incorrectly filled in the voting papers. Three years later it was 5.7 per cent, or 1363 votes.
Candidates for the Wanganui mayoralty, Wanganui District Council and the Horizons Regional Council are elected through the First Past the Post (FPP) system. Under FPP voters tick only one preferred candidate out of three for the mayoralty, 12 candidates out of 36 for the district council and two out of three for the regional council.
