The byelection which saw Winston Peters swagger in as the new Northland member of Parliament cost a bomb as well as put a bomb under the National Government.
Of the almost $1 million cost of the recent byelection, over $300,000 was spent informing and educating Northlanders about the voting process itself, according to the Electoral Commission.
A breakdown on how the byelection's $947,000 budget allocation was spent showed public information was the commission's largest single expense, at $307,000.
The next biggest expense was paying staff to operate advanced voting and election booths - a cost of $284,000. About 300 paid staff worked in 84 voting places or electoral headquarters on voting day itself, as well as staff at special polls before the March 28 election day.
Enrolment services, including enrolment publications, EasyVote information packs and local enrolment outreach activity cost $117,000, while leasing and running the electorate headquarters and voting places cost $78,000.
