Following the 2008 election a rule change allowed advance voting for virtually any reason.
Almost a fifth of those likely to vote in this year's election have already done so with through advance voting, with two days still to go - a result that is likely to force a rethink of electoral advertising rules.
The Electoral Commission yesterday confirmed a total of 434,197 advance votes had been cast so far. Assuming a similar turnout this election to that in 2011, that works out about 19 per cent of the total vote.
The figure has already easily topped the 334,558 advance votes or 15 per cent of the total cast in 2011 which was the first election held under rules that meant anybody could advance vote. But with most parties promoting early voting, this year's total appears all but certain to top the 500,000 mark.
Laila Harre who led the union sponsored Get out and Vote campaign before becoming internet Party Leader this year said she was "very, very happy to see the massive increase".
